From 3ba500dee327e0261e728edec8a4f2f563d2760c Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Tue, 31 May 2022 15:47:35 +0300 Subject: arm64: dts: qcom: sdm845: use dispcc AHB clock for mdss node 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.
