Subject: [PATCH] drm/amd/display: change FIFO reset condition to embedded display only
Date: Wed, 19 Jan 2022 22:21:36 +0000	[thread overview]
Message-ID: <DM4PR12MB5214E88D148D9643F8CE62199E599@DM4PR12MB5214.namprd12.prod.outlook.com> (raw)

[Public]

[Why]
FIFO reset is only necessary for fast boot sequence, where otg is disabled
and dig fe is enabled when changing dispclk. Fast boot is only enabled
on embedded displays.

[How]
Change FIFO reset condition to "embedded display only".
