Hi,
This patchset adds drivers and bindings to the following devices: - Exynos DSI master, - S6E8AA0 DSI panel, - TC358764 DSI/LVDS bridge, - HV070WSA-100 LVDS panel.
It adds also display support in DTS files for the following boards: - Exynos4210/Trats, - Exynos4412/Trats2, - Exynos5250/Arndale.
Things worth mentioning:
1. I have implemented DSI/LVDS bridge using drm_panel framework, ie. the driver exposes drm_panel interface on DSI side, and interact with panels on LVDS side using drm_panel framework. This approach seems to me simpler and more natural than using drm_bridge.
2. I have used video interface bindings to make link between bridge and LVDS panel. Other places where such links can be created are: a) link between DSI master and slave, I wonder if it is always neccessary, DSI bus is also video bus, b) link between FIMD(display controller) and DSI Master, currently Exynos DRM framework uses driver's hardcoded links, converting it to video interface bindings should be done (if required) by separate patches.
The patchset is based on Sean's Paul Exynos refactor patches v4 [1]. To work properly porch calculation should be fixed according to my comment [2].
It is the 2nd iteration of the patches, main changes: - based on v4 refactor patches, - added arndale related stuff. Other changes are described in individual patches.
