2016-04-14drm/vc4: Add DPI driverEric Anholt
The DPI interface involves taking a ton of our GPIOs to be used as outputs, and routing display signals over them in parallel. v2: Use display_info.bus_formats[] to replace our custom DT properties. v3: Rebase on V3D documentation changes. v4: Fix rebase detritus from V3D documentation changes.

2015-10-21drm/vc4: Add devicetree bindings for VC4.Eric Anholt
VC4 is the GPU (display and 3D) subsystem present on the 2835 and some other Broadcom SoCs. This binding follows the model of msm, imx, sti, and others, where there is a subsystem node for the whole GPU, with nodes for the individual HW components within it. v2: Extend the commit message, fix several nits from Stephen Warren. v3: Rename the compatibility strings, clean up node names, drop the unnecessary lists of components. Use compatibility strings for choosing CRTC HVS channel numbers. Document the HDMI clock usage. v4: Whitespace fix, expand acronyms, move to display/ instead of gpu/, rename "hpd-gpio" to "hpd-gpios". Signed-off-by: Eric Anholt <eric@anholt.net>
