From: Jonghwa Lee Date: Mon, 27 Apr 2015 11:36:36 +0000 (+0900) Subject: clk: exynos5433: Add CLK_IGNORE_UNUSED flag to clocks for SMC X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=80e7264c8f1b9b2ca73bc8db327fb3b73e626b7b;p=linux-beck.git clk: exynos5433: Add CLK_IGNORE_UNUSED flag to clocks for SMC This patch adds 'CLK_IGNORE_UNUSED' flag to clocks which is required for operation of secure monitor call (smc). System will hang when it executes 'smc' with one of those clock is gated. All related clocks must be enabled.
