H A D | dcn30_hwseq.h | 985faf2c Mon Dec 07 10:53:46 CST 2020 Wesley Chalmers <Wesley.Chalmers@amd.com> drm/amd/display: New sequence for HUBP blank
[WHY] DCN30 has a bug where blanking HUBP blocks pstate allow unless HUBP_DISABLE is toggled afterwards.
[HOW] Create a HW sequence for blanking HUBP. 1. Wait for enter VBLANK 2. Set HUBP_BLANK 3. Make sure HUBP_IN_BLANK = 1 4. Toggle HUBP_DISABLE on and off to perform soft reset
All existing calls to hubp->funcs->set_blank should be replaced with this new sequence. In wait_for_mpcc_disconnect, only blank the pipe being disconnected, and leave all other pipes unmodified.
