[linux-sunxi] [PATCH] drm/sun4i: hdmi: Implement I2C adapter for A10s DDC bus

The drm_get_edid function should be used instead of drm_do_get_edid by exposing the DDC bus as an I2C adapter. Implement this for A10s. Signed-off-by: Jonathan Liu <net...@gmail.com> --- drivers/gpu/drm/sun4i/Makefile | 1 + drivers/gpu/drm/sun4i/sun4i_hdmi.h | 11 ++- drive
