From ca082355b542710fd07559ee05f6975c2768344b Mon Sep 17 00:00:00 2001 From: Chanwoo Choi Date: Mon, 27 Apr 2015 20:36:28 +0900 Subject: [PATCH 1/6] clk: Use CONFIG_ARCH_EXYNOS instead of CONFIG_ARCH_EXYNOS5433 This patch removes the CONFIG_ARCH_EXYNOS5433 and then use only the CONFIG_ARCH_EXYNOS for ARM-64bit Exynos5433 SoC.

But the clock needs to be ungated prior suspend to allow the system to be suspend and resumed correctly. Add GATE_BUS_TOP register to the list of registers to be restored when the system enters into a suspend state so aclk266_g2d will be ungated. Thanks to Abhilash Kesavan for figuring out that this was the issue.
