+Sharp Microelectronics 10.1" WQXGA TFT LCD panel
+
+This panel requires a dual-channel DSI host to operate. It supports two modes:
+- left-right: each channel drives the left or right half of the screen
+- even-odd: each channel drives the even or odd lines of the screen
+
+Each of the DSI channels controls a separate DSI peripheral. The peripheral
+driven by the first link (DSI-LINK1), left or even, is considered the primary
+peripheral and controls the device. The 'link2' property contains a phandle
+to the peripheral driven by the second link (DSI-LINK2, right or odd).
+
+Note that in video mode the DSI-LINK1 interface always provides the left/even
+pixels and DSI-LINK2 always provides the right/odd pixels. In command mode it
+is possible to program either link to drive the left/even or right/odd pixels
+but for the sake of consistency this binding assumes that the same assignment
+is chosen as for video mode.
+
+Required properties:
+- compatible: should be "sharp,lq101r1sx01"
+- reg: DSI virtual channel of the peripheral
+
+Required properties (for DSI-LINK1 only):
+- link2: phandle to the DSI peripheral on the secondary link. Note that the
+ presence of this property marks the containing node as DSI-LINK1.
+- power-supply: phandle of the regulator that provides the supply voltage
+
+Optional properties (for DSI-LINK1 only):
+- backlight: phandle of the backlight device attached to the panel
+
+Example:
+
+ dsi@54300000 {
+ panel: panel@0 {
+ compatible = "sharp,lq101r1sx01";
+ reg = <0>;
+
+ link2 = <&secondary>;

+ power-supply = <...>;
+ backlight = <...>;

+Analog Device ADV7511(W)/13 HDMI Encoders
+-----------------------------------------
+
+The ADV7511, ADV7511W and ADV7513 are HDMI audio and video transmitters
+compatible with HDMI 1.4 and DVI 1.0. They support color space conversion,
+S/PDIF, CEC and HDCP.
+
+Required properties:
+
+- compatible: Should be one of "adi,adv7511", "adi,adv7511w" or "adi,adv7513"
+- reg: I2C slave address
+
+The ADV7511 supports a large number of input data formats that differ by their
+color depth, color format, clock mode, bit justification and random
+arrangement of components on the data bus. The combination of the following
+properties describe the input and map directly to the video input tables of the
+ADV7511 datasheet that document all the supported combinations.
+
+- adi,input-depth: Number of bits per color component at the input (8, 10 or
+ 12).
+- adi,input-colorspace: The input color space, one of "rgb", "yuv422" or
+ "yuv444".
+- adi,input-clock: The input clock type, one of "1x" (one clock cycle per
+ pixel), "2x" (two clock cycles per pixel), "ddr" (one clock cycle per pixel,
+ data driven on both edges).
+
+The following input format properties are required except in "rgb 1x" and
+"yuv444 1x" modes, in which case they must not be specified.
+
+- adi,input-style: The input components arrangement variant (1, 2 or 3), as
+ listed in the input format tables in the datasheet.
+- adi,input-justification: The input bit justification ("left", "evenly",
+ "right").
+
+Optional properties:
+
+- interrupts: Specifier for the ADV7511 interrupt
+- pd-gpios: Specifier for the GPIO connected to the power down signal
+
+- adi,clock-delay: Video data clock delay relative to the pixel clock, in ps
+ (-1200 ps .. 1600 ps). Defaults to no delay.
+- adi,embedded-sync: The input uses synchronization signals embedded in the
+ data stream (similar to BT.656). Defaults to separate H/V synchronization
+ signals.
+
+Required nodes:
+
+The ADV7511 has two video ports. Their connections are modelled using the OF
+graph bindings specified in Documentation/devicetree/bindings/graph.txt.
+
+- Video port 0 for the RGB or YUV input
+- Video port 1 for the HDMI output
+
+
+Example
+-------
+
+ adv7511w: hdmi@39 {
+ compatible = "adi,adv7511w";
+ reg = <39>;
+ interrupt-parent = <&gpio3>;
+ interrupts = <29 IRQ_TYPE_EDGE_FALLING>;
+
+ adi,input-depth = <8>;
+ adi,input-colorspace = "rgb";
+ adi,input-clock = "1x";
+ adi,input-style = <1>;
+ adi,input-justification = "evenly";

-************************************************************
-* For the very latest on DRI development, please see: *
-* http://dri.freedesktop.org/ *
-************************************************************
-
-The Direct Rendering Manager (drm) is a device-independent kernel-level
-device driver that provides support for the XFree86 Direct Rendering
-Infrastructure (DRI).
-
-The DRM supports the Direct Rendering Infrastructure (DRI) in four major
-ways:
-
- 1. The DRM provides synchronized access to the graphics hardware via
- the use of an optimized two-tiered lock.
-
- 2. The DRM enforces the DRI security policy for access to the graphics
- hardware by only allowing authenticated X11 clients access to
- restricted regions of memory.
-
- 3. The DRM provides a generic DMA engine, complete with multiple
- queues and the ability to detect the need for an OpenGL context
- switch.
-
- 4. The DRM is extensible via the use of small device-specific modules
- that rely extensively on the API exported by the DRM module.
-
-
-Documentation on the DRI is available from:
- http://dri.freedesktop.org/wiki/Documentation
- http://sourceforge.net/project/showfiles.php?group_id=387
- http://dri.sourceforge.net/doc/
-
-For specific information about kernel-level support, see:
-
- The Direct Rendering Manager, Kernel Support for the Direct Rendering
- Infrastructure

-
- Hardware Locking for the Direct Rendering Infrastructure

+ * The primary memory I/O features being added for revisions of gfxip
+ * beyond 7.0 (Kaveri) are:
+ *
+ * Access to ATC/IOMMU mapped memory w/ associated extension of VA to 48b
+ *
+ * “Flat” shader memory access – These are new shader vector memory
+ * operations that do not reference a T#/V# so a “pointer” is what is
+ * sourced from the vector gprs for direct access to memory.
+ * This pointer space has the Shared(LDS) and Private(Scratch) memory
+ * mapped into this pointer space as apertures.
+ * The hardware then determines how to direct the memory request
+ * based on what apertures the request falls in.
+ *
+ * Unaligned support and alignment check
+ *
+ *
+ * System Unified Address - SUA
+ *
+ * The standard usage for GPU virtual addresses are that they are mapped by
+ * a set of page tables we call GPUVM and these page tables are managed by
+ * a combination of vidMM/driver software components. The current virtual
+ * address (VA) range for GPUVM is 40b.
+ *
+ * As of gfxip7.1 and beyond we’re adding the ability for compute memory
+ * clients (CP/RLC, DMA, SHADER(ifetch, scalar, and vector ops)) to access
+ * the same page tables used by host x86 processors and that are managed by
+ * the operating system. This is via a technique and hardware called ATC/IOMMU.
+ * The GPU has the capability of accessing both the GPUVM and ATC address
+ * spaces for a given VMID (process) simultaneously and we call this feature
+ * system unified address (SUA).
+ *
+ * There are three fundamental address modes of operation for a given VMID
+ * (process) on the GPU:
+ *
+ * HSA64 – 64b pointers and the default address space is ATC
+ * HSA32 – 32b pointers and the default address space is ATC
+ * GPUVM – 64b pointers and the default address space is GPUVM (driver
+ * model mode)
+ *
+ *
+ * HSA64 - ATC/IOMMU 64b
+ *
+ * A 64b pointer in the AMD64/IA64 CPU architecture is not fully utilized
+ * by the CPU so an AMD CPU can only access the high area
+ * (VA[63:47] == 0x1FFFF) and low area (VA[63:47 == 0) of the address space
+ * so the actual VA carried to translation is 48b. There is a “hole” in
+ * the middle of the 64b VA space.
+ *
+ * The GPU not only has access to all of the CPU accessible address space via
+ * ATC/IOMMU, but it also has access to the GPUVM address space. The “system
+ * unified address” feature (SUA) is the mapping of GPUVM and ATC address
+ * spaces into a unified pointer space. The method we take for 64b mode is
+ * to map the full 40b GPUVM address space into the hole of the 64b address
+ * space.
+
+ * The GPUVM_Base/GPUVM_Limit defines the aperture in the 64b space where we
+ * direct requests to be translated via GPUVM page tables instead of the
+ * IOMMU path.
+ *
+ *
+ * 64b to 49b Address conversion
+ *
+ * Note that there are still significant portions of unused regions (holes)
+ * in the 64b address space even for the GPU. There are several places in
+ * the pipeline (sw and hw), we wish to compress the 64b virtual address
+ * to a 49b address. This 49b address is constituted of an “ATC” bit
+ * plus a 48b virtual address. This 49b address is what is passed to the
+ * translation hardware. ATC==0 means the 48b address is a GPUVM address
+ * (max of 2^40 – 1) intended to be translated via GPUVM page tables.
+ * ATC==1 means the 48b address is intended to be translated via IOMMU
+ * page tables.
+ *
+ * A 64b pointer is compared to the apertures that are defined (Base/Limit), in
+ * this case the GPUVM aperture (red) is defined and if a pointer falls in this
+ * aperture, we subtract the GPUVM_Base address and set the ATC bit to zero
+ * as part of the 64b to 49b conversion.
+ *
+ * Where this 64b to 49b conversion is done is a function of the usage.
+ * Most GPU memory access is via memory objects where the driver builds
+ * a descriptor which consists of a base address and a memory access by
+ * the GPU usually consists of some kind of an offset or Cartesian coordinate
+ * that references this memory descriptor. This is the case for shader
+ * instructions that reference the T# or V# constants, or for specified
+ * locations of assets (ex. the shader program location). In these cases
+ * the driver is what handles the 64b to 49b conversion and the base
+ * address in the descriptor (ex. V# or T# or shader program location)
+ * is defined as a 48b address w/ an ATC bit. For this usage a given
+ * memory object cannot straddle multiple apertures in the 64b address
+ * space. For example a shader program cannot jump in/out between ATC
+ * and GPUVM space.
+ *
+ * In some cases we wish to pass a 64b pointer to the GPU hardware and
+ * the GPU hw does the 64b to 49b conversion before passing memory
+ * requests to the cache/memory system. This is the case for the
+ * S_LOAD and FLAT_* shader memory instructions where we have 64b pointers
+ * in scalar and vector GPRs respectively.
+ *
+ * In all cases (no matter where the 64b -> 49b conversion is done), the gfxip
+ * hardware sends a 48b address along w/ an ATC bit, to the memory controller
+ * on the memory request interfaces.
+ *
+ * <client>_MC_rdreq_atc // read request ATC bit
+ *
+ * 0 : <client>_MC_rdreq_addr is a GPUVM VA
+ *
+ * 1 : <client>_MC_rdreq_addr is a ATC VA
+ *
+ *
+ * “Spare” aperture (APE1)
+ *
+ * We use the GPUVM aperture to differentiate ATC vs. GPUVM, but we also use
+ * apertures to set the Mtype field for S_LOAD/FLAT_* ops which is input to the
+ * config tables for setting cache policies. The “spare” (APE1) aperture is
+ * motivated by getting a different Mtype from the default.
+ * The default aperture isn’t an actual base/limit aperture; it is just the
+ * address space that doesn’t hit any defined base/limit apertures.
+ * The following diagram is a complete picture of the gfxip7.x SUA apertures.
+ * The APE1 can be placed either below or above
+ * the hole (cannot be in the hole).
+ *
+ *
+ * General Aperture definitions and rules
+ *
+ * An aperture register definition consists of a Base, Limit, Mtype, and
+ * usually an ATC bit indicating which translation tables that aperture uses.
+ * In all cases (for SUA and DUA apertures discussed later), aperture base
+ * and limit definitions are 64KB aligned.
+ *
+ * <ape>_Base[63:0] = { <ape>_Base_register[63:16], 0x0000 }
+ *
+ * <ape>_Limit[63:0] = { <ape>_Limit_register[63:16], 0xFFFF }
+ *
+ * The base and limit are considered inclusive to an aperture so being
+ * inside an aperture means (address >= Base) AND (address <= Limit).
+ *
+ * In no case is a payload that straddles multiple apertures expected to work.
+ * For example a load_dword_x4 that starts in one aperture and ends in another,
+ * does not work. For the vector FLAT_* ops we have detection capability in
+ * the shader for reporting a “memory violation” back to the
+ * SQ block for use in traps.
+ * A memory violation results when an op falls into the hole,
+ * or a payload straddles multiple apertures. The S_LOAD instruction
+ * does not have this detection.
+ *
+ * Apertures cannot overlap.
+ *
+ *
+ *
+ * HSA32 - ATC/IOMMU 32b
+ *
+ * For HSA32 mode, the pointers are interpreted as 32 bits and use a single GPR
+ * instead of two for the S_LOAD and FLAT_* ops. The entire GPUVM space of 40b
+ * will not fit so there is only partial visibility to the GPUVM
+ * space (defined by the aperture) for S_LOAD and FLAT_* ops.
+ * There is no spare (APE1) aperture for HSA32 mode.
+ *
+ *
+ * GPUVM 64b mode (driver model)
+ *
+ * This mode is related to HSA64 in that the difference really is that
+ * the default aperture is GPUVM (ATC==0) and not ATC space.
+ * We have gfxip7.x hardware that has FLAT_* and S_LOAD support for
+ * SUA GPUVM mode, but does not support HSA32/HSA64.
+ *
+ *
+ * Device Unified Address - DUA
+ *
+ * Device unified address (DUA) is the name of the feature that maps the
+ * Shared(LDS) memory and Private(Scratch) memory into the overall address
+ * space for use by the new FLAT_* vector memory ops. The Shared and
+ * Private memories are mapped as apertures into the address space,
+ * and the hardware detects when a FLAT_* memory request is to be redirected
+ * to the LDS or Scratch memory when it falls into one of these apertures.
+ * Like the SUA apertures, the Shared/Private apertures are 64KB aligned and
+ * the base/limit is “in” the aperture. For both HSA64 and GPUVM SUA modes,
+ * the Shared/Private apertures are always placed in a limited selection of
+ * options in the hole of the 64b address space. For HSA32 mode, the
+ * Shared/Private apertures can be placed anywhere in the 32b space
+ * except at 0.
+ *
+ *
+ * HSA64 Apertures for FLAT_* vector ops
+ *
+ * For HSA64 SUA mode, the Shared and Private apertures are always placed
+ * in the hole w/ a limited selection of possible locations. The requests
+ * that fall in the private aperture are expanded as a function of the
+ * work-item id (tid) and redirected to the location of the
+ * “hidden private memory”. The hidden private can be placed in either GPUVM
+ * or ATC space. The addresses that fall in the shared aperture are
+ * re-directed to the on-chip LDS memory hardware.
+ *
+ *
+ * HSA32 Apertures for FLAT_* vector ops
+ *
+ * In HSA32 mode, the Private and Shared apertures can be placed anywhere
+ * in the 32b space except at 0 (Private or Shared Base at zero disables
+ * the apertures). If the base address of the apertures are non-zero
+ * (ie apertures exists), the size is always 64KB.
+ *
+ *
+ * GPUVM Apertures for FLAT_* vector ops
+ *
+ * In GPUVM mode, the Shared/Private apertures are specified identically
+ * to HSA64 mode where they are always in the hole at a limited selection
+ * of locations.
+ *
+ *
+ * Aperture Definitions for SUA and DUA
+ *
+ * The interpretation of the aperture register definitions for a given
+ * VMID is a function of the “SUA Mode” which is one of HSA64, HSA32, or
+ * GPUVM64 discussed in previous sections. The mode is first decoded, and
+ * then the remaining register decode is a function of the mode.
+ *
+ *
+ * SUA Mode Decode
+ *
+ * For the S_LOAD and FLAT_* shader operations, the SUA mode is decoded from
+ * the COMPUTE_DISPATCH_INITIATOR:DATA_ATC bit and
+ * the SH_MEM_CONFIG:PTR32 bits.
+ *
+ * COMPUTE_DISPATCH_INITIATOR:DATA_ATC SH_MEM_CONFIG:PTR32 Mode
+ *
+ * 1 0 HSA64
+ *
+ * 1 1 HSA32
+ *
+ * 0 X GPUVM64
+ *
+ * In general the hardware will ignore the PTR32 bit and treat
+ * as “0” whenever DATA_ATC = “0”, but sw should set PTR32=0
+ * when DATA_ATC=0.
+ *
+ * The DATA_ATC bit is only set for compute dispatches.
+ * All “Draw” dispatches are hardcoded to GPUVM64 mode
+ * for FLAT_* / S_LOAD operations.

+ *
+ * MQD stands for Memory Queue Descriptor which represents the current queue
+ * state in the memory and initiate the HQD (Hardware Queue Descriptor) state.
+ * This structure is actually a base class for the different types of MQDs
+ * structures for the variant ASICs that should be supported in the future.
+ * This base class is also contains all the MQD specific operations.
+ * Another important thing to mention is that each queue has a MQD that keeps

+ * Basically there are a instances of the mqd manager class per MQD type per
+ * ASIC. Currently the kfd driver supports only Kaveri so there are instances
+ * per KFD_MQD_TYPE for each device.

+ * DOC: overview
+ *
+ * This helper library provides implementations of check and commit functions on
+ * top of the CRTC modeset helper callbacks and the plane helper callbacks. It
+ * also provides convenience implementations for the atomic state handling
+ * callbacks for drivers which don't need to subclass the drm core structures to
+ * add their own additional internal state.
+ *
+ * This library also provides default implementations for the check callback in
+ * drm_atomic_helper_check and for the commit callback with
+ * drm_atomic_helper_commit. But the individual stages and callbacks are expose
+ * to allow drivers to mix and match and e.g. use the plane helpers only
+ * together with a driver private modeset implementation.
+ *
+ * This library also provides implementations for all the legacy driver
+ * interfaces on top of the atomic interface. See drm_atomic_helper_set_config,
+ * drm_atomic_helper_disable_plane, drm_atomic_helper_disable_plane and the
+ * various functions to implement set_property callbacks. New drivers must not
+ * implement these functions themselves but must use the provided helpers.

+ * or flushing the work items, depending upon whether the driver can deal with
+ * cancelled updates. Note that it is important to ensure that the framebuffer
+ * cleanup is still done when cancelling.
+ *
+ * For sufficient parallelism it is recommended to have a work item per crtc
+ * (for updates which don't touch global state) and a global one. Then we only
+ * need to synchronize with the crtc work items for changed crtcs and the global
+ * work item, which allows nice concurrent updates on disjoint sets of crtcs.
+ *
+ * 3. The software state is updated synchronously with
+ * drm_atomic_helper_swap_state. Doing this under the protection of all modeset
+ * locks means concurrent callers never see inconsistent state. And doing this
+ * while it's guaranteed that no relevant async worker runs means that async
+ * workers do not need grab any locks. Actually they must not grab locks, for
+ * otherwise the work flushing will deadlock.
+ *
+ * 4. Schedule a work item to do all subsequent steps, using the split-out
+ * commit helpers: a) pre-plane commit b) plane commit c) post-plane commit and
+ * then cleaning up the framebuffers after the old framebuffer is no longer
+ * being displayed.

+ * The CRTC modeset helper library provides a default set_config implementation

+ * the same callbacks which drivers can use to e.g. restore the modeset
+ * configuration on resume with drm_helper_resume_force_mode().
+ *
+ * The driver callbacks are mostly compatible with the atomic modeset helpers,
+ * except for the handling of the primary plane: Atomic helpers require that the
+ * primary plane is implemented as a real standalone plane and not directly tied
+ * to the CRTC state. For easier transition this library provides functions to
+ * implement the old semantics required by the CRTC helpers using the new plane
+ * and atomic helper callbacks.
+ *
+ * Drivers are strongly urged to convert to the atomic helpers (by way of first
+ * converting to the plane helpers). New drivers must not use these functions
+ * but need to implement the atomic interface instead, potentially using the
+ * atomic helpers for that.

+ * DOC: overview
+ *
+ * This helper library has two parts. The first part has support to implement
+ * primary plane support on top of the normal CRTC configuration interface.
+ * Since the legacy ->set_config interface ties the primary plane together with
+ * the CRTC state this does not allow userspace to disable the primary plane
+ * itself. To avoid too much duplicated code use
+ * drm_plane_helper_check_update() which can be used to enforce the same
+ * restrictions as primary planes had thus. The default primary plane only
+ * expose XRBG8888 and ARGB8888 as valid pixel formats for the attached
+ * framebuffer.
+ *
+ * Drivers are highly recommended to implement proper support for primary
+ * planes, and newly merged drivers must not rely upon these transitional
+ * helpers.
+ *
+ * The second part also implements transitional helpers which allow drivers to
+ * gradually switch to the atomic helper infrastructure for plane updates. Once
+ * that switch is complete drivers shouldn't use these any longer, instead using
+ * the proper legacy implementations for update and disable plane hooks provided
+ * by the atomic helpers.
+ *
+ * Again drivers are strongly urged to switch to the new interfaces.

+ * DOC: High Definition Audio over HDMI and Display Port
+ *
+ * The graphics and audio drivers together support High Definition Audio over
+ * HDMI and Display Port. The audio programming sequences are divided into audio
+ * codec and controller enable and disable sequences. The graphics driver
+ * handles the audio codec sequences, while the audio driver handles the audio
+ * controller sequences.
+ *
+ * The disable sequences must be performed before disabling the transcoder or
+ * port. The enable sequences may only be performed after enabling the
+ * transcoder and port, and after completed link training.
+ *
+ * The codec and controller sequences could be done either parallel or serial,
+ * but generally the ELDV/PD change in the codec sequence indicates to the audio
+ * driver that the controller sequence should start. Indeed, most of the
+ * co-operation between the graphics and audio drivers is handled via audio
+ * related registers. (The notable exception is the power management, not

+ * debug display issues, especially watermark settings.
+ *
+ * If an underrun is detected this is logged into dmesg. To avoid flooding logs

+ * occurrence until the next modeset on a given pipe.
+ *
+ * Note that underrun detection on gmch platforms is a bit more ugly since there
+ * is no interrupt (despite that the signalling bit is in the PIPESTAT pipe
+ * interrupt register). Also on some other platforms underrun interrupts are
+ * shared, which means that if we detect an underrun we need to disable underrun
+ * reporting on all pipes.
+ *
+ * The code also supports underrun detection on the PCH transcoder.

+/**
+ * DOC: frontbuffer tracking
+ *
+ * Many features require us to track changes to the currently active
+ * frontbuffer, especially rendering targeted at the frontbuffer.
+ *
+ * To be able to do so GEM tracks frontbuffers using a bitmask for all possible
+ * frontbuffer slots through i915_gem_track_fb(). The function in this file are
+ * then called when the contents of the frontbuffer are invalidated, when
+ * frontbuffer rendering has stopped again to flush out all the changes and when
+ * the frontbuffer is exchanged with a flip. Subsystems interested in
+ * frontbuffer changes (e.g. PSR, FBC, DRRS) should directly put their callbacks
+ * into the relevant places and filter for the frontbuffer slots that they are
+ * interested int.
+ *
+ * On a high level there are two types of powersaving features. The first one
+ * work like a special cache (FBC and PSR) and are interested when they should
+ * stop caching and when to restart caching. This is done by placing callbacks
+ * into the invalidate and the flush functions: At invalidate the caching must
+ * be stopped and at flush time it can be restarted. And maybe they need to know
+ * when the frontbuffer changes (e.g. when the hw doesn't initiate an invalidate
+ * and flush on its own) which can be achieved with placing callbacks into the
+ * flip functions.
+ *
+ * The other type of display power saving feature only cares about busyness
+ * (e.g. DRRS). In that case all three (invalidate, flush and flip) indicate
+ * busyness. There is no direct way to detect idleness. Instead an idle timer
+ * work delayed work should be started from the flush and flip functions and
+ * cancelled as soon as busyness is detected.
+ *
+ * Note that there's also an older frontbuffer activity tracking scheme which
+ * just tracks general activity. This is done by the various mark_busy and
+ * mark_idle functions. For display power management features using these
+ * functions is deprecated and should be avoided.

+/**
+ * DOC: Panel Self Refresh (PSR/SRD)
+ *
+ * Since Haswell Display controller supports Panel Self-Refresh on display
+ * panels witch have a remote frame buffer (RFB) implemented according to PSR
+ * spec in eDP1.3. PSR feature allows the display to go to lower standby states
+ * when system is idle but display is on as it eliminates display refresh
+ * request to DDR memory completely as long as the frame buffer for that
+ * display is unchanged.
+ *
+ * Panel Self Refresh must be supported by both Hardware (source) and
+ * Panel (sink).
+ *
+ * PSR saves power by caching the framebuffer in the panel RFB, which allows us
+ * to power down the link and memory controller. For DSI panels the same idea
+ * is called "manual mode".
+ *
+ * The implementation uses the hardware-based PSR support which automatically
+ * enters/exits self-refresh mode. The hardware takes care of sending the
+ * required DP aux message and could even retrain the link (that part isn't
+ * enabled yet though). The hardware also keeps track of any frontbuffer
+ * changes to know when to exit self-refresh mode again. Unfortunately that
+ * part doesn't work too well, hence why the i915 PSR support uses the
+ * software frontbuffer tracking to make sure it doesn't miss a screen
+ * update. For this integration intel_psr_invalidate() and intel_psr_flush()
+ * get called by the frontbuffer tracking code. Note that because of locking
+ * issues the self-refresh re-enable code is done from a work queue, which
+ * must be correctly synchronized/cancelled when shutting down the pipe."

+ * since on the GT side a lot of the power management is done by the hardware.
+ * But even there some manual control at the device level is required.
+ *
+ * Since i915 supports a diverse set of platforms with a unified codebase and
+ * hardware engineers just love to shuffle functionality around between power
+ * domains there's a sizeable amount of indirection required. This file provides
+ * generic functions to the driver for grabbing and releasing references for

-Missing features (not necessarily for moving out of staging):
-
-- Add support for IC (Image converter)
-- Add support for CSI (CMOS Sensor interface)
-- Add support for VDIC (Video Deinterlacer)
-
-Many work-in-progress patches for the above features exist. Contact
