From: Marek Szyprowski Date: Fri, 18 Nov 2016 10:04:18 +0000 (+0100) Subject: clk: exynos5433: Mark some clocks as critical X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=37bf4ab84be2ae00f116436eb2c876a0ca953a64;p=linux-beck.git 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.
