[PATCH 2/2] drm/vc4: Add DSI driver

2017-01-23 Thread Eric Anholt
The DSI0 and DSI1 blocks on the 2835 are related hardware blocks. Some registers move around, and the featureset is slightly different, as DSI1 (the 4-lane DSI) is a later version of the hardware block. This driver doesn't yet enable DSI0, since we don't have any hardware to test against, but it do
