Subject: arm64: dts: qcom: sc7280: Enable MDP turbo mode
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d0d6230aa9652afc2c96a83eb2d217761683cad8;p=linux.git

arm64: dts: qcom: sc7280: Enable MDP turbo mode

The max frequency listed in the DPU opp-table is 506MHz, this is not
sufficient to drive a 4k@60 display, resulting in constant underrun.

Add the missing MDP_CLK turbo frequency of 608MHz to the opp-table to
fix this.
