Subject: [PATCH v2 5/5] arm64: dts: qcom: sm8250: Add GPU speedbin support
Date: Fri, 20 Jan 2023 18:22:33 +0100 [thread overview]
Message-ID: <20230120172233.1905761-6-konrad.dybcio@linaro.org> (raw)
In-Reply-To: <20230120172233.1905761-1-konrad.dybcio@linaro.org>
SM8250 has (at least) four GPU speed bins. With the support added on the
driver side, wire up bin detection in the DTS to restrict lower-quality
SKUs from running at frequencies they were not validated at.
Tested-by: Marijn Suijten <marijn.suijten@somainline.org> # On Sony Xperia 5 II (speed bin 0x7)
Reviewed-by: Marijn Suijten <marijn.suijten@somainline.org>
