In preparation for working on DSI panel support, I wrote the much simpler support for DPI panels. I've tested it on the 7" DPI panel from Adafruit, with panel-simple support included here.
Eric Anholt (5): of: Add vendor prefix for On Tat Industrial Company. panel-simple: Add the 7" DPI panel from Adafruit. drm: Add an encoder and connector type enum for DPI. drm/vc4: Add DPI driver ARM: bcm2835: Add the DPI hardware to the device tree.
