[PATCH] drm/rockchip: vop: add rk3188 vop definitions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The rk3188 has 2 vops not using iommus which only output directly
to a rgb interface per vop. So all other output modes like hdmi
are provided by external brige chips.

This depends on Sandy's + mine recent series enabling direct
rgb outputs of specific vops.
