Merge branch '2016-02-26-st-drm-next' of http://git.linaro.org/people/benjamin.gaignard/kernel into drm-next
Here are sti patches for drm-next.
It brings:
- The support of the atomic_check for the planes and minor fixes for
planes
- The support of the vendor specific infoframe for HDMI and the
support of 2 HDMI properties related to the connector
- The support of the DVO solving panel detection issue and timing issue.
- The support of debugfs for connectors, encoders, crtcs and planes.

+ * irq callers. However, all those calls to us are happening with the

+ * we must let that one pass through in order to not lose vblank counts
+ * during vblank irq off - which would completely defeat the whole

+ *
+ * Whenever we are called from vblank irq, we have to assume concurrent
+ * readers exist or can show up any time during our execution, even if
+ * the refcount is currently zero, as vblank irqs are usually only
+ * enabled due to the presence of readers, and because when we are called

+ * Secure boot is the process by which NVIDIA-signed firmware is loaded into

+ * A Falcon microprocessor supporting advanced security modes can run in one of

+ * - Non-secure (NS). In this mode, functionality is similar to Falcon

+ * disabled (on certain Falcon instances). This is the only possible mode that
+ * can be used if you don't have microcode cryptographically signed by NVIDIA.

+ * not possible to read or write any Falcon internal state or Falcon registers
+ * from outside the Falcon (for example, from the host system). The only way
+ * to enable this mode is by loading microcode that has been signed by NVIDIA.
+ * (The loading process involves tagging the IMEM block as secure, writing the
+ * signature into a Falcon register, and starting execution. The hardware will
+ * validate the signature, and if valid, grant HS privileges.)
+ *
+ * - Light Secure (LS). In this mode, the microprocessor has more privileges
+ * than NS but fewer than HS. Some of the microprocessor state is visible to
+ * host software to ease debugging. The only way to enable this mode is by HS
+ * microcode enabling LS mode. Some privileges available to HS mode are not
+ * available here. LS mode is introduced in GM20x.
+ *
+ * Secure boot consists in temporarily switching a HS-capable falcon (typically
+ * PMU) into HS mode in order to validate the LS firmwares of managed falcons,
+ * load them, and switch managed falcons into LS mode. Once secure boot
+ * completes, no falcon remains in HS mode.
+ *
+ * Secure boot requires a write-protected memory region (WPR) which can only be
+ * written by the secure falcon. On dGPU, the driver sets up the WPR region in
+ * video memory. On Tegra, it is set up by the bootloader and its location and
+ * size written into memory controller registers.
+ *
+ * The secure boot process takes place as follows:
+ *
+ * 1) A LS blob is constructed that contains all the LS firmwares we want to
+ * load, along with their signatures and bootloaders.
+ *
+ * 2) A HS blob (also called ACR) is created that contains the signed HS
+ * firmware in charge of loading the LS firmwares into their respective
+ * falcons.
+ *
+ * 3) The HS blob is loaded (via its own bootloader) and executed on the
+ * HS-capable falcon. It authenticates itself, switches the secure falcon to
+ * HS mode and setup the WPR region around the LS blob (dGPU) or copies the
+ * LS blob into the WPR region (Tegra).
+ *
+ * 4) The LS blob is now secure from all external tampering. The HS falcon
+ * checks the signatures of the LS firmwares and, if valid, switches the
+ * managed falcons to LS mode and makes them ready to run the LS firmware.
+ *
+ * 5) The managed falcons remain in LS mode and can be started.

+ * multiple interfaces.
+ *
+ * 2) The databook does not mention doing more DEPXFERCFG for new
+ * endpoint on alt setting (8.1.6).
+ *
+ * The following simplified method is used instead:
+ *
+ * All hardware endpoints can be assigned a transfer resource and this
+ * setting will stay persistent until either a core reset or
+ * hibernation. So whenever we do a DEPSTARTCFG(0) we can go ahead and
+ * do DEPXFERCFG for every hardware endpoint as well. We are
+ * guaranteed that there are as many transfer resources as endpoints.
