From: Javier Martinez Canillas Date: Sat, 24 Jan 2015 04:25:01 +0000 (+0900) Subject: clk: exynos5420: Add IDs for clocks used in DISP1 power domain X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=8856010029985ba4d63a8942deb7f9e780285dd2;p=deliverable%2Flinux.git clk: exynos5420: Add IDs for clocks used in DISP1 power domain When a power domain is powered off on Exynos5420 SoC, the input clocks of the devices attached to this power domain are re-parented to oscclk and restored to the original parent after powering on the power domain. So a reference to the input and parent clocks for the devices attached to a power domain are needed to be able to do the re-parenting. The DISP1 pd includes modules which uses the following clocks: ACLK_200_DISP1 (MIXER and HDMILINK) ACLK_300_DISP1 (FIMD1) ACLK_400_DISP1 (Internal Buses) Each of these clocks are generated as the output of a clock mux so add an ID for all of these clock muxes and their parents to be referenced in the DISP1 power domain device node.
