drm/amd/display: Set vsc pack revision when DPCD revision is >= 1.2

2018-05-30T06:17:42+00:00

[ Upstream commit 3b94a4007dcfd4ac5780cd3d8a2d99979c966073 ] Brightness couldn't change when booting up in DC mode. It was because "psr_enabled" flag was not set to true before setting vsc packet revision, causing packet rev setup was skipped. Now instead of checking the psr flag, it checks if the DPCD_REV >= 1.2 and set the vsc packet revision.

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: 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.
