Add support for drm_bridge On 8MQ and 8MM, the LCDIF block is not directly connected to a parallel display connector, where an LCD panel can be attached, but instead it is connected to DSI controller. Since this DSI stands between the display controller (eLCDIF) and the physical connector, the DSI can be implemented as a DRM bridge. So, in order to be able to connect the mxsfb driver to the DSI driver, the support for a drm_bridge was needed in mxsfb DRM driver (the actual driver for the eLCDIF block). 2. Add support for additional pixel formats Some of the pixel formats needed by Android were not implemented in this driver, but they were actually supported. So, add support for them. 3. Few minor features and bug-fixing The addition of max-res DT property was actually needed in order to limit the bandwidth usage of the eLCDIF block. This is need on systems where multiple display controllers are presend and the memory bandwidth is not enough to handle all of them at maximum capacity (like it is the case on 8MQ, where there are two display controllers: DCSS and eLCDIF). The rest of the patches are bug-fixes.
