[ 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 wenst@chromium.org Reviewed-by: Nícolas F.
