[PATCH 22/26] drm/rockchip: vop: test for P{H,V}SYNC

Show all headers | View raw

When connected to the MIPI DSI output, we need to use N{H,V}SYNC for the
internal connection but these flags are meaningless for DSI panels.
Switch the test so that we do not set the P{H,V}SYNC bits unless the
mode requires it.
