Subject: [PATCH 14/33] drm/amd/display: Allow PHY state update between same states
Date: Sat, 27 Aug 2022 06:50:34 +0800	[thread overview]
Message-ID: <20220826225053.1435588-15-Brian.Chang@amd.com> (raw)
In-Reply-To: <20220826225053.1435588-1-Brian.Chang@amd.com>

From: Taimur Hassan <Syed.Hassan@amd.com>

[Why & How]
In some cases, there are calls to transition from TX_ON to TX_ON, such as
when using MST or during resolution change. This is expected, so allow HW
programming to continue.
