From 2feed5aecf5f367b92bd6b6e92afe9e3de466907 Mon Sep 17 00:00:00 2001 From: Abhilash Kesavan Date: Wed, 11 Dec 2013 17:27:05 +0530 Subject: [PATCH] clk: samsung: exynos5250: Add CLK_IGNORE_UNUSED flag for the sysreg clock The sysreg (system register) generates control signals for various blocks like disp1blk, i2c, mipi, usb etc. However, it gets disabled as an unused clock at boot-up. This can lead to failures in operation of above blocks, because they can not be configured properly if this clock is disabled.
