Subject: [PATCH] arm64: dts: qcom: sdm845: use dispcc AHB clock for mdss node
Date: Tue, 31 May 2022 15:47:35 +0300 [thread overview]
Message-ID: <20220531124735.1165582-1-dmitry.baryshkov@linaro.org> (raw)
It was noticed that on sdm845 after an MDSS suspend/resume cycle the
driver can not read HW_REV registers properly (they will return 0
instead). Chaning the "iface" clock from <&gcc GCC_DISP_AHB_CLK> to
<&dispcc DISP_CC_MDSS_AHB_CLK> fixes the issue.
Fixes: 08c2a076d18f ("arm64: dts: qcom: sdm845: Add dpu to sdm845 dts file")
Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
