[GIT PULL v2] MT8173 DRM support

[GIT PULL v2] MT8173 DRM support

[Philipp Zabel]

Hi Dave,

second try. Please consider pulling this tag with initial MediaTek
MT8173 DRM support, fixed to allow compiling as modules and without the
device tree changes.

regards
Philipp

MT8173 DRM support

- device tree binding documentation for all MT8173 display
  subsystem components
- basic mediatek drm driver for MT8173 with two optional,
  currently fixed output paths:
- DSI encoder support for DSI and (via bridge) eDP panels
- DPI encoder support for output to HDMI bridge
- necessary clock tree changes for the DPI->HDMI path

The first two are missing symbol exports, it may be due to my config,
the last looks like
somewhere should be using do_div or one of the other div helpers.
possibly in mtk_mipi_tx.c where it does a 64-bit divide.

I've sent a mtk_smi patch to export the missing functions and will
respin the patch series as v15 with the division in mtk_mipi_tx fixed
and Daniel's comments addressed.
