[GIT PULL v3] MT8173 DRM support

[Philipp Zabel]

Hi Dave,

third try and last minute pull request for v4.7. I have addressed
Daniel's comment about drm_dev_register()/drm_connector_register_all(),
but I've missed his request to use gem_free_object_unlocked() until just
now. If that can be fixed up afterwards, please consider merging this
tag with initial MediaTek MT8173 DRM support.

Changes since v16:
 - Call drm_dev_register() after mtk_drm_kms_init() in mtk_drm_drv
 - Call drm_connector_register_all() in mtk_drm_drv
 - Drop drm_connector_(un)register calls from mtk_dsi

regards
Philipp

  clk: mediatek: remove hdmitx_dig_cts from TOP clocks (2016-05-06 17:47:42 +0200)

----------------------------------------------------------------
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
- export mtk-smi functions used by mediatek-drm
