      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.

      Included in this set are:
      - an update from Jean-Francois to add the missing reg documentation entry
        to the device tree documentation.
      - conversion of the tda998x driver to the component helpers.

      Merge branch 'msm-next' of git://people.freedesktop.org/~robclark/linux into drm-next · eceb55a0
      Dave Airlie authored
      This time around we have a mix of new hw enablement (mdp5 v1.3 /
      apq8084), plus devicetree and various upstream changes (mostly
      adapting to CCF vs downstream clk driver differences) for mdp4 /
      apq8064.  With these drm/msm patches plus a few other small patchsets
      (from linaro qcom integration branch.. mostly stuff queued up for
      3.17) we have the inforce ifc6410 board working, with gpu.  Much nicer
      to work with than ancient vendor android branch :-)
