Subject: [PATCH] drm/connector: Allow creation of margin props alone
|
|
|
|
Commit 6c4f52dca36f5e3e2354c30591d38e92f4657ed9 upstream.
|
|
|
|
TV margins properties can only be added as part of the SDTV TV
|
|
connector properties creation, but we might need those props for HDMI
|
|
TVs too, so let's move the margins props creation in a separate
|
|
function and expose it to drivers.
|
|
|
|
We also add an helper to attach margins props to a connector.
