Subject: [PATCH 11/45] drm/amd/display: update bw formula to v252
Date: Tue, 11 Dec 2018 17:57:17 -0500 [thread overview]
Message-ID: <1544569071-7114-12-git-send-email-sunpeng.li@amd.com> (raw)
In-Reply-To: <1544569071-7114-1-git-send-email-sunpeng.li-5C7GfCeVMHo@public.gmane.org>
From: Eric Yang <Eric.Yang2@amd.com>
[why]
There was a recent fix in the BW spreadsheet to allow timing with very
large vblank. Need to be ported into driver.
