Revert "drm/amd/display: disable CRTCs with NULL FB on their primary plane (V2)"

2018-04-24T07:43:03+00:00

commit 1cb19e8267a57c5174da09e0d52d1477baceccca upstream.

Revert until we've found a proper fix for the flickering and lock-ups.

This reverts commit 36cc549d59864b7161f0e23d710c1c4d1b9cf022.

drm/amd/display: Add one to EDID's audio channel count when passing to DC

2018-03-21T05:24:47+00:00

DC takes channel count to mean the actual count. cea_sad's channels
represent it as number of channels - 1.

drm/amd/display: We shouldn't set format_default on plane as atomic driver

2018-03-21T05:23:51+00:00

This is still a leftover from early atomic brinup days.

drm/amd/display: Allow truncation to 10 bits

2018-03-21T05:22:08+00:00

The truncation isn't being programmed if the truncation
depth is set to 2, it causes an issue with dce11.2 asic
using 6bit eDP panel. It required to truncate 12:10 in order to
perform spatial dither 10:6.

This change will allow 12:10 truncation to be enabled.

drm/amd/display: validate plane format on primary plane

2018-03-07T21:31:19+00:00

In dce110, the plane configuration is such that plane 0
or the primary plane should be rendered with only RGB data.

This patch adds the validation to ensure that no video data
is rendered on plane 0.
