Subject: [PATCH] drm/vc4: Fix VIC usage with Broadcast RGB
|
|
|
|
Adding the Broadcast RGB range selection broke the VIC
|
|
field of the AVI infoframes on HDMI, zeroing them for all
|
|
modes on an HDMI monitor.
|
|
|
|
Correct this so that it is only zeroed if the range is
|
|
contrary to the standard range of the mode.
