Subject: [PATCH] drm/vc4: Set TV margins on the composite connector state

The Raspberry Pi bootloader can pass a set of margin values to the
|
|
kernel cmdline as part of the video= option. These should result in
|
|
black borders on the output to compensate for TVs where the visible area
|
|
on the screen is smaller than the full extents of the video image.
|
|
|
|
With the VC4 driver this currently works on an HDMI connector, but not
|
|
on a composite video connector.
|
|
|
|
The TV margins from the kernel cmdline are available in the
|
|
drm_cmdline_mode structure of the composite video connector. Apply them
|
|
to the connector state in the connector reset function. This is how it
|
|
is implemented for the VC4 HDMI connector.
