From cfc7588a310254b659cb0a6fcca1fffd3f223090 Mon Sep 17 00:00:00 2001 From: Alim Akhtar Date: Wed, 26 Aug 2015 09:00:42 +0530 Subject: [PATCH] clk: samsung: exynos7: Fix CMU TOP1 block As per UM, sclk_mmc2 is bit 16 of SEL_TOP1_FSYS0. Also the DIV and the GATE clocks are at bit 16 in their respective registers. For mmc1 and mmc0 clock MUXs are in TOP1_FSYS11 instead of TOP1_FSYS1. And their DIV and GATE clks are in xxx_TOP1_FSYS11 instead of TOP1_FSYS1. This patch corrects it. This also adds xxx_FSYS11 to be saved/restore during s2r cycles.
