Subject: [PATCH v2 4/6] clk: tegra20: init NDFLASH clock to sensible rate
Date: Sun, 27 May 2018 23:54:40 +0200 [thread overview]
Message-ID: <20180527215442.14760-5-stefan@agner.ch> (raw)
From: Lucas Stach <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.
