This pull is missing nouveau, Ben has been stuck trying to track down
a very longstanding bug that revealed itself due to some other
changes. I've asked him to send you a direct pull request for nouveau

It has one trivial conflict with your tree in armada_drv.c, and also
the pull request contains some component changes that are already in

Merge branch 'drm_kms_for_next-v8' of git://git.linaro.org/people/benjamin.gaignard/kernel into drm-next

This series of patches add the support of DRM/KMS drivers for STMicroelectronics
chipsets stih416 and stih407.

Hardware is split in two main blocks: Compositor and TVout. Each of them
includes specific hardware IPs and the display timing are controlled by a specific
Video Timing Generator hardware IP (VTG).

Compositor is made of the follow hardware IPs:
- GDP (Generic Display Pipeline) which is an entry point for graphic (RGB)
buffers
- VDP (Video Diplay Pipeline) which is an entry point for video (YUV) buffers
- HQVDP (High Quality Video Display Processor) that supports scaling,
deinterlacing and some miscellaneous image quality improvements.
It fetches the Video decoded buffers from memory, processes them and pushes
them to the Compositor through a HW dedicated bus.
- Mixer is responsible of mixing all the entries depending of their
respective z-order and layout

TVout is divided in 3 parts:
- HDMI to generate HDMI signals, depending of chipset version HDMI phy can
change.
- HDA to generate signals for HD analog TV
- VIP to control/switch data path coming from Compositor

On stih416 compositor and Tvout are on different dies so a Video Trafic Advance
inter-die Communication mechanism (VTAC) is needed.

+-----------------------------------------------------------------+

In addition of the drivers for the IPs listed before a thin I2C driver (hdmiddc) is used
by HDMI driver to retrieve EDID for monitor.

To unify interfaces of GDP and VDP we create a "layer" interface called by
compositor to control both GPD and VDP.

Hardware have memory contraints (alignment, contiguous) so we use CMA drm helpers functions
to allocate frame buffer.

File naming convention is:
- sti_* for IPs drivers
- sti_drm_* for drm functions implementation.
