[PATCH v3] drm/mxsfb: use bus_format to determine LCD bus width

2016-12-14 Thread Stefan Agner
The LCD bus width does not need to align with the pixel format. The LCDIF controller automatically converts between pixel formats and bus width by padding or dropping LSBs. The DRM subsystem has the notion of bus_format which allows to determine what bus_formats are supported by the display.
