From 37bf4ab84be2ae00f116436eb2c876a0ca953a64 Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Fri, 18 Nov 2016 11:04:18 +0100 Subject: [PATCH] clk: exynos5433: Mark some clocks as critical Some parent clocks of the Exynos5433 CMUs must be always enabled to access any register in the given CMU or devices connected to it. For the time being, until a proper solution based on runtime PM is applied, mark those clocks as critical (instead of ignore unused) to prevent disabling them.
