From 9caf2d956cfa254c6d89c5f4d7b3f8235d75b28f Mon Sep 17 00:00:00 2001 From: Georgi Djakov Date: Mon, 9 Nov 2020 14:45:12 +0200 Subject: [PATCH] interconnect: qcom: msm8974: Don't boost the NoC rate during boot It has been reported that on Fairphone 2 (msm8974-based), increasing the clock rate for some of the NoCs during boot may lead to hangs. Let's restore the original behavior and not touch the clock rate of any of the NoCs to fix the regression.
