Subject: [RESEND] venus: fix calculating mbps in calculate_inst_freq()
Date:   Mon,  2 Nov 2020 16:01:37 +0530
Message-Id: <1604313097-2178-1-git-send-email-mansur@codeaurora.org>
Precedence: bulk

Currently in calculate_inst_freq(), video driver is calculating
macro blocks per frame in stead of macro blocks per second(mpbs).
Which results frequency is always setting to lower frequency (150MB)
as per frequency table for sc7180. Hence the playback is not smooth.

Corrected this by correcting the mbps calculation in calculate_inst_freq().
