Actually this "color-bpp" should come from crtc driver, maybe should
come from
"struct drm_crtc {".
Like rockchip stuffs, analogix_dp-rockchip call an mode_config from
rockchip_drm_vop
driver and set output mode to RGB[10:10:10], then vop driver just store
the output mode
type to the private struct "vop->connecot_out_mode". do think that this
outmode should
store into crtc, not just come from DT prop.
