Subject: [PATCH 1/5] clk: samsung: exynos5250: Add CLK_IGNORE_UNUSED flag for the sysreg clock
Date: Wed, 11 Dec 2013 17:27:05 +0530	[thread overview]
Message-ID: <1386763029-8516-2-git-send-email-a.kesavan@samsung.com> (raw)
In-Reply-To: <1386763029-8516-1-git-send-email-a.kesavan@samsung.com>

The sysreg (system register) generates control signals for various blocks
like disp1blk, i2c, mipi etc. However, it gets disabled as an unused clock
at boot-up.
