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.
Signed-off-by: Heiko Stuebner heiko@sntech.de --- This depends on Sandy's + mine recent series enabling direct rgb outputs of specific vops.
