If anyone has any objections, please let me know. ------------------ From: Chen-Yu Tsai [ Upstream commit 2ba776f903cb7157e80b5f314fb0b4faf6ea6958 ] The DRM DP code has macros for the DP power sequencing commands. Use them in the anx7625 driver instead of raw numbers. Fixes: 548b512e144f ("drm/bridge: anx7625: send DPCD command to downstream") Fixes: 27f26359de9b ("drm/bridge: anx7625: Set downstream sink into normal status") Signed-off-by: Chen-Yu Tsai Reviewed-by: Nícolas F.
