[PATCH v4 0/5] vc4/hdmi: Support TV margin props

[Boris Brezillon]

Hello,

As suggested by Ville, this version uses the already available TV
margin props to define left/right/top/bottom margins insted of adding
new underscan props.

This works pretty well for what we want to do in VC4: allow one to
define the visible area on a TV.

The first 2 patches are fixing the existing doc, patch 3 is allowing
one to create and attach TV margins independently of the TV connector
props. Finally, patch 4 and 5 add support for those props to the VC4
driver.

Regards,

Boris
