Subject: [PATCH v2 3/5] clk: tegra20: init NDFLASH clock to sensible rate
Date: Wed, 8 Apr 2015 21:46:08 +0200 [thread overview]
Message-ID: <1428522370-18035-4-git-send-email-dev@lynxeye.de> (raw)
In-Reply-To: <1428522370-18035-1-git-send-email-dev@lynxeye.de>
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.
