Subject: [PATCH 720/725] drm/vc4: Attach margin props to the HDMI connector
|
|
|
|
Commit db999538fdb0679629d90652f8a1437df1e85a7d upstream.
|
|
|
|
Now that the plane code takes the margins setup into account, we can
|
|
safely attach margin props to the HDMI connector.
|
|
|
|
We also take care of filling AVI infoframes correctly to expose the
|
|
top/botton/left/right bar.
|
|
|
|
Note that those margin props match pretty well the
|
|
overscan_{left,right,top,bottom} properties defined in config.txt and
|
|
parsed by the VC4 firmware.
