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.

drm/amd/display: Fix takover from VGA mode

2018-03-07T21:28:32+00:00

HW Engineer's Notes:
 During switch from vga->extended, if we set the VGA_TEST_ENABLE and then
 hit the VGA_TEST_RENDER_START, then the DCHUBP timing gets updated correctly.
 Then vBIOS will have it poll for the VGA_TEST_RENDER_DONE and unset
 VGA_TEST_ENABLE, to leave it in the same state as before.

drm/amd/display: Fix memleaks when atomic check fails.

2018-03-07T21:28:22+00:00

While checking plane states for updates during atomic check, we create
dc_plane_states in preparation. These dc states should be freed if
something errors.

Although the input transfer function is also freed by
dc_plane_state_release(), we should free it (on error) under the same
scope as where it is created.
