[PATCH 0/15] drm: sun4i: Add support for the HDMI controller

Hi, Here is an attempt at getting the HDMI controller running. This HDMI controller is found on a number of old Allwinner SoCs (A10, A10s, A20, A31). This driver only supports for now the A10s because it was an easy target, being very close to the A13 that is already supported by our DRM driver.
