The rk3288 MIPI DSI is a Synopsys DesignWare MIPI DSI host controller

controller DRM driver.
The MIPI DSI feature is tested on rk3288 evb board, backport them to
chrome os kernel chrome_v3.14, and it can display normally.
This patchset is base on the patchset from Ying.liu@xxxxxxxxxxxxx.

According to the suggestion from Thierry, I have get rid of the bridge,
and register the encoder & connecter in drm/rockchip/dw-mipi-dsi.c.
I've raised this question too late, but what was the reason to not
implement the DSI block as a bridge driver?
The drm/hisilicon IP seems to use a very similar DSI Designware IP (the
register offsets seems to be the same). There is a good potential of
re-use here by different kms drivers here the way it's already done for
DW HDMI and the analogix DP driver that's in review process.
Archit
After backport below patches from linux-next, I can merge this serial into
Dave's drm-next branch.
