DRM_MIPI_DSI is included via both "select" and "depends on", this is trouble waiting to happen since this will result in different behavior depending on which is used.
As Thierry said 'select' is for DSI controllers, 'depends on' for DSI devices, why is it problematic? What kind of troubles do you expect?
This patch resolves the problem by:
- Converting all inclusion to "select" since DRM_MIPI_DSI is not a menu item.
- Remove "depends on DRM" since "select"ing DRM_MIPI_DSI won't include DRM anyways, so this is misleading.
I suppose "depends on DRM" should mean the code enabled by symbol DRM_MIPI_DSI uses code enabled by symbol DRM, ie maybe removal of this symbol is OK (if dsi framework does not depends on DRM), but the reason is incorrect IMHO.
