Subject: [PATCH] arm64: dts: qcom: sc7280: Update gpu opp table
Date:   Mon, 29 Aug 2022 01:10:55 +0530
Message-ID: <20220829011035.1.Ie3564662150e038571b7e2779cac7229191cf3bf@changeid>
MIME-Version: 1.0

Precedence: bulk

On the lite sku where GPU Fmax is 550Mhz, voting for a slightly higher
bandwidth at the highest gpu opp helps to improve "Manhattan offscreen"
score by 10%. Update the gpu opp table such that this is applicable only
on SKUs which has 550Mhz as GPU Fmax.
