Subject: [v1] drm/msm/dpu: update bandwidth threshold check
Date: Mon, 4 May 2020 19:01:03 +0530 [thread overview]
Message-ID: <1588599063-15754-1-git-send-email-mkrishn@codeaurora.org> (raw)
Maximum allowed bandwidth has no dependency on the type
of panel used. Hence, cleanup the code to use max_bw_high
as the threshold value for bandwidth checks.
Update the maximum allowed bandwidth as 6.8Gbps for
SC7180 target.
