drm/amd/display: Support long vblank feature [WHY] We want to support low hz case, but the original vtotal/vtotal_min/vtotal_max can't support more than 0x7FFF. [HOW] We use the 2 HW reg to contorl long vblank case. 1. OTG_V_COUNT_STOP_CONTROL -> vcount_stop 2. OTG_V_COUNT_STOP_CONTROL2 -> vcount_stop_timer vcount_stop define from which line we stop using vcount and start using vcount2. vcount_stop_timer define how long we use vcount2. Ex: Vtotal = 7 OTG_V_COUNT_STOP_CONTROL = 4 OTG_V_COUNT_STOP_CONTROL2 = 5 time : 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 vcount : 0, 1, 2, 3, - - - - - 4, 5, 6 vcount2 : 0, 1, 2, 3, 4, Reviewed-by: Jun Lei <jun.lei@amd.com> Acked-by: Alex Hung <alex.hung@amd.com> Signed-off-by: ChunTao Tso <chuntao.tso@amd.com> Signed-off-by: Robin Chen<robin.chen@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
