Subject: [PATCH] ARM: Exynos4: Turn off clocks for NAND, OneNAND and TSI controllers
Date: Fri, 24 Aug 2012 20:22:16 +0530	[thread overview]
Message-ID: <1345819936-6503-1-git-send-email-chander.kashyap@linaro.org> (raw)

The clocks for NAND, OneNAND and Transport Stream Interface(TSI)
controllers could be either enabled or disabled at boot. To ensure
that these are turned off until used, add them to the list of clocks
to be turned off during boot.
