From c07c1a0f68d0f2f7ca9aff924e2772526027b019 Mon Sep 17 00:00:00 2001 From: Andrzej Pietrasiewicz Date: Fri, 29 Sep 2017 09:32:53 +0200 Subject: clk: samsung: Fix m2m scaler clock on Exynos542x The TOP "aclk400_mscl" clock should be kept enabled all the time to allow proper access to power management control for MSC power domain and devices that are a part of it. This change is required for the scaler to work properly after domain power on/off sequence.
