drm/rockchip: vop: Fix color for RGB888/BGR888 format on VOP full
[ Upstream commit bb0a05ac ] Use of DRM_FORMAT_RGB888 and DRM_FORMAT_BGR888 on e.g. RK3288, RK3328 and RK3399 result in wrong colors being displayed. The issue can be observed using modetest: modetest -s <connector_id>@<crtc_id>:1920x1080-60@RG24 modetest -s <connector_id>@<crtc_id>:1920x1080-60@BG24 Vendor 4.4 kernel apply an inverted rb swap for these formats on VOP full framework (IP version 3.x) compared to VOP little framework (2.x). Fix colors by applying different rb swap for VOP full framework (3.x) and VOP little framework (2.x) similar to vendor 4.4 kernel.
