+ MFP Configuration for PXA2xx/PXA3xx Processors
+
+ Eric Miao <eric.miao@marvell.com>
+
+MFP stands for Multi-Function Pin, which is the pin-mux logic on PXA3xx and
+later PXA series processors. This document describes the existing MFP API,
+and how board/platform driver authors could make use of it.
+
+ Basic Concept
+===============
+
+Unlike the GPIO alternate function settings on PXA25x and PXA27x, a new MFP
+mechanism is introduced from PXA3xx to completely move the pin-mux functions
+out of the GPIO controller. In addition to pin-mux configurations, the MFP
+also controls the low power state, driving strength, pull-up/down and event
+detection of each pin. Below is a diagram of internal connections between
+the MFP logic and the remaining SoC peripherals:
+
+ +--------+
+ | |--(GPIO19)--+
+ | GPIO | |
+ | |--(GPIO...) |
+ +--------+ |
+ | +---------+
+ +--------+ +------>| |
+ | PWM2 |--(PWM_OUT)-------->| MFP |
+ +--------+ +------>| |-------> to external PAD
+ | +---->| |
+ +--------+ | | +-->| |
+ | SSP2 |---(TXD)----+ | | +---------+
+ +--------+ | |
+ | |
+ +--------+ | |
+ | Keypad |--(MKOUT4)----+ |
+ +--------+ |
+ |
+ +--------+ |
+ | UART2 |---(TXD)--------+
+ +--------+
+
+NOTE: the external pad is named as MFP_PIN_GPIO19, it doesn't necessarily
+mean it's dedicated for GPIO19, only as a hint that internally this pin
+can be routed from GPIO19 of the GPIO controller.
+
+To better understand the change from PXA25x/PXA27x GPIO alternate function
+to this new MFP mechanism, here are several key points:
+
+ 1. GPIO controller on PXA3xx is now a dedicated controller, same as other
+ internal controllers like PWM, SSP and UART, with 128 internal signals
+ which can be routed to external through one or more MFPs (e.g. GPIO<0>
+ can be routed through either MFP_PIN_GPIO0 as well as MFP_PIN_GPIO0_2,
+ see arch/arm/mach-pxa/mach/include/mfp-pxa300.h)
+
+ 2. Alternate function configuration is removed from this GPIO controller,
+ the remaining functions are pure GPIO-specific, i.e.
+
+ - GPIO signal level control
+ - GPIO direction control
+ - GPIO level change detection
+
+ 3. Low power state for each pin is now controlled by MFP, this means the
+ PGSRx registers on PXA2xx are now useless on PXA3xx
+
+ 4. Wakeup detection is now controlled by MFP, PWER does not control the
+ wakeup from GPIO(s) any more, depending on the sleeping state, ADxER
+ (as defined in pxa3xx-regs.h) controls the wakeup from MFP
+
+NOTE: with such a clear separation of MFP and GPIO, by GPIO<xx> we normally
+mean it is a GPIO signal, and by MFP<xxx> or pin xxx, we mean a physical
+pad (or ball).
+
+ MFP API Usage
+===============
+
+For board code writers, here are some guidelines:
+
+1. include ONE of the following header files in your <board>.c:
+
+ - #include <mach/mfp-pxa25x.h>
+ - #include <mach/mfp-pxa27x.h>
+ - #include <mach/mfp-pxa300.h>
+ - #include <mach/mfp-pxa320.h>
+ - #include <mach/mfp-pxa930.h>
+
+ NOTE: only one file in your <board>.c, depending on the processors used,
+ because pin configuration definitions may conflict in these file (i.e.
+ same name, different meaning and settings on different processors). E.g.
+ for zylonite platform, which support both PXA300/PXA310 and PXA320, two
+ separate files are introduced: zylonite_pxa300.c and zylonite_pxa320.c
+ (in addition to handle MFP configuration differences, they also handle
+ the other differences between the two combinations).
+
+ NOTE: PXA300 and PXA310 are almost identical in pin configurations (with
+ PXA310 supporting some additional ones), thus the difference is actually
+ covered in a single mfp-pxa300.h.
+
+2. prepare an array for the initial pin configurations, e.g.:
+
+ static unsigned long mainstone_pin_config[] __initdata = {
+ /* Chip Select */
+ GPIO15_nCS_1,
+
+ /* LCD - 16bpp Active TFT */
+ GPIOxx_TFT_LCD_16BPP,
+ GPIO16_PWM0_OUT, /* Backlight */
+
+ /* MMC */
+ GPIO32_MMC_CLK,
+ GPIO112_MMC_CMD,
+ GPIO92_MMC_DAT_0,
+ GPIO109_MMC_DAT_1,
+ GPIO110_MMC_DAT_2,
+ GPIO111_MMC_DAT_3,
+
+ ...
+
+ /* GPIO */
+ GPIO1_GPIO | WAKEUP_ON_EDGE_BOTH,
+ };
+
+ a) once the pin configurations are passed to pxa{2xx,3xx}_mfp_config(),
+ and written to the actual registers, they are useless and may discard,
+ adding '__initdata' will help save some additional bytes here.
+
+ b) when there is only one possible pin configurations for a component,
+ some simplified definitions can be used, e.g. GPIOxx_TFT_LCD_16BPP on
+ PXA25x and PXA27x processors
+
+ c) if by board design, a pin can be configured to wake up the system
+ from low power state, it can be 'OR'ed with any of:
+
+ WAKEUP_ON_EDGE_BOTH
+ WAKEUP_ON_EDGE_RISE
+ WAKEUP_ON_EDGE_FALL
+ WAKEUP_ON_LEVEL_HIGH - specifically for enabling of keypad GPIOs,
+
+ to indicate that this pin has the capability of wake-up the system,
+ and on which edge(s). This, however, doesn't necessarily mean the
+ pin _will_ wakeup the system, it will only when set_irq_wake() is
+ invoked with the corresponding GPIO IRQ (GPIO_IRQ(xx) or gpio_to_irq())
+ and eventually calls gpio_set_wake() for the actual register setting.
+
+ d) although PXA3xx MFP supports edge detection on each pin, the
+ internal logic will only wakeup the system when those specific bits
+ in ADxER registers are set, which can be well mapped to the
+ corresponding peripheral, thus set_irq_wake() can be called with
+ the peripheral IRQ to enable the wakeup.
+
+
+ MFP on PXA3xx
+===============
+
+Every external I/O pad on PXA3xx (excluding those for special purpose) has
+one MFP logic associated, and is controlled by one MFP register (MFPR).
+
+The MFPR has the following bit definitions (for PXA300/PXA310/PXA320):
+
+ 31 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
+ +-------------------------+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
+ | RESERVED |PS|PU|PD| DRIVE |SS|SD|SO|EC|EF|ER|--| AF_SEL |
+ +-------------------------+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
+
+ Bit 3: RESERVED
+ Bit 4: EDGE_RISE_EN - enable detection of rising edge on this pin
+ Bit 5: EDGE_FALL_EN - enable detection of falling edge on this pin
+ Bit 6: EDGE_CLEAR - disable edge detection on this pin
+ Bit 7: SLEEP_OE_N - enable outputs during low power modes
+ Bit 8: SLEEP_DATA - output data on the pin during low power modes

+ Bit 14: PULLUP_EN - enable the internal pull-up resistor on this pin
+ Bit 15: PULL_SEL - pull state controlled by selected alternate function
+ (0) or by PULL{UP,DOWN}_EN bits (1)
+
+ Bit 0 - 2: AF_SEL - alternate function selection, 8 possibilities, from 0-7

+
+ MFP Design for PXA2xx/PXA3xx
+==============================
+
+Due to the difference of pin-mux handling between PXA2xx and PXA3xx, a unified
+MFP API is introduced to cover both series of processors.
+
+The basic idea of this design is to introduce definitions for all possible pin
+configurations, these definitions are processor and platform independent, and
+the actual API invoked to convert these definitions into register settings and
+make them effective there-after.
+

+
+ Pin Configuration
+ -----------------
+
+ The following comments are copied from mfp.h (see the actual source code
+ for most updated info)
+
+ /*
+ * a possible MFP configuration is represented by a 32-bit integer
+ *
+ * bit 0.. 9 - MFP Pin Number (1024 Pins Maximum)
+ * bit 10..12 - Alternate Function Selection
+ * bit 13..15 - Drive Strength
+ * bit 16..18 - Low Power Mode State
+ * bit 19..20 - Low Power Mode Edge Detection
+ * bit 21..22 - Run Mode Pull State
+ *
+ * to facilitate the definition, the following macros are provided
+ *
+ * MFP_CFG_DEFAULT - default MFP configuration value, with
+ * alternate function = 0,
+ * drive strength = fast 3mA (MFP_DS03X)
+ * low power mode = default
+ * edge detection = none
+ *
+ * MFP_CFG - default MFPR value with alternate function
+ * MFP_CFG_DRV - default MFPR value with alternate function and
+ * pin drive strength
+ * MFP_CFG_LPM - default MFPR value with alternate function and
+ * low power mode
+ * MFP_CFG_X - default MFPR value with alternate function,
+ * pin drive strength and low power mode
+ */
+
+ Examples of pin configurations are:
+
+ #define GPIO94_SSP3_RXD MFP_CFG_X(GPIO94, AF1, DS08X, FLOAT)
+
+ which reads GPIO94 can be configured as SSP3_RXD, with alternate function
+ selection of 1, driving strength of 0b101, and a float state in low power
+ modes.
+
+ NOTE: this is the default setting of this pin being configured as SSP3_RXD
+ which can be modified a bit in board code, though it is not recommended to
+ do so, simply because this default setting is usually carefully encoded,
+ and is supposed to work in most cases.
+
+ Register Settings
+ -----------------
+
+ Register settings on PXA3xx for a pin configuration is actually very
+ straight-forward, most bits can be converted directly into MFPR value
+ in a easier way. Two sets of MFPR values are calculated: the run-time
+ ones and the low power mode ones, to allow different settings.
+
+ The conversion from a generic pin configuration to the actual register
+ settings on PXA2xx is a bit complicated: many registers are involved,
+ including GAFRx, GPDRx, PGSRx, PWER, PKWR, PFER and PRER. Please see
+ mfp-pxa2xx.c for how the conversion is made.

+Overlay Support for PXA27x and later LCD controllers
+====================================================
+
+ PXA27x and later processors support overlay1 and overlay2 on-top of the
+ base framebuffer (although under-neath the base is also possible). They
+ support palette and no-palette RGB formats, as well as YUV formats (only
+ available on overlay2). These overlays have dedicated DMA channels and
+ behave in a similar way as a framebuffer.
+
+ However, there are some differences between these overlay framebuffers
+ and normal framebuffers, as listed below:
+
+ 1. overlay can start at a 32-bit word aligned position within the base
+ framebuffer, which means they have a start (x, y). This information
+ is encoded into var->nonstd (no, var->xoffset and var->yoffset are
+ not for such purpose).
+
+ 2. overlay framebuffer is allocated dynamically according to specified
+ 'struct fb_var_screeninfo', the amount is decided by:
+
+ var->xres_virtual * var->yres_virtual * bpp
+
+ bpp = 16 -- for RGB565 or RGBT555
+ = 24 -- for YUV444 packed
+ = 24 -- for YUV444 planar
+ = 16 -- for YUV422 planar (1 pixel = 1 Y + 1/2 Cb + 1/2 Cr)
+ = 12 -- for YUV420 planar (1 pixel = 1 Y + 1/4 Cb + 1/4 Cr)
+
+ NOTE:
+
+ a. overlay does not support panning in x-direction, thus
+ var->xres_virtual will always be equal to var->xres
+
+ b. line length of overlay(s) must be on a 32-bit word boundary,
+ for YUV planar modes, it is a requirement for the component
+ with minimum bits per pixel, e.g. for YUV420, Cr component
+ for one pixel is actually 2-bits, it means the line length
+ should be a multiple of 16-pixels
+
+ c. starting horizontal position (XPOS) should start on a 32-bit
+ word boundary, otherwise the fb_check_var() will just fail.
+
+ d. the rectangle of the overlay should be within the base plane,
+ otherwise fail
+
+ Applications should follow the sequence below to operate an overlay
+ framebuffer:
+
+ a. open("/dev/fb[1-2]", ...)
+ b. ioctl(fd, FBIOGET_VSCREENINFO, ...)
+ c. modify 'var' with desired parameters:
+ 1) var->xres and var->yres
+ 2) larger var->yres_virtual if more memory is required,
+ usually for double-buffering
+ 3) var->nonstd for starting (x, y) and color format
+ 4) var->{red, green, blue, transp} if RGB mode is to be used
+ d. ioctl(fd, FBIOPUT_VSCREENINFO, ...)
+ e. ioctl(fd, FBIOGET_FSCREENINFO, ...)
+ f. mmap
+ g. ...
+
+ 3. for YUV planar formats, these are actually not supported within the
+ framebuffer framework, application has to take care of the offsets
+ and lengths of each component within the framebuffer.
+
+ 4. var->nonstd is used to pass starting (x, y) position and color format,
+ the detailed bit fields are shown below:
+
+ 31 23 20 10 0
