Subject: [PATCH 2/4] clk: tegra20: init NDFLASH clock to sensible rate
Date: Sun,  4 Jan 2015 21:39:18 +0100	[thread overview]
Message-ID: <1420403960-26626-2-git-send-email-dev@lynxeye.de> (raw)
In-Reply-To: <1420403960-26626-1-git-send-email-dev-8ppwABl0HbeELgA04lAiVw@public.gmane.org>

Set up the NAND Flash controller clock to run at 150MHz
instead of the rate set by the bootloader. This is a
conservative rate which also yields good performance.
