Subject: [PATCH 09/21] drm/amd/display: removed unnecessary check when dpp clock increasing
Date: Fri,  8 Jan 2021 16:49:55 -0500	[thread overview]
Message-ID: <20210108215007.851249-10-Rodrigo.Siqueira@amd.com> (raw)
In-Reply-To: <20210108215007.851249-1-Rodrigo.Siqueira@amd.com>

From: Chiawen Huang <chiawen.huang@amd.com>

[Why]
When switching single pipe to split pipe, the bandwidth check is just
for first pipe.  The 2nd pipe with abnormal(or zero) dpp clock when pipe
ready and unlock leads the garbage on display.

[How]
Removed external increasing dpp clock check, the internal function
already loops all of pipes to check whether update dpp clock.
