Subject: [PATCH] omap: Enable GPMC clock in gpmc_init
Date: Wed, 20 Jan 2010 22:39:29 +0000 [thread overview]
Message-ID: <mailman.157.1264039704.2170.linux-arm-kernel@lists.infradead.org> (raw)
Don't assume that gpmc_l3_clk is on, enable it before touching
configuration registers.
Note that the current code assumes that this clock is always
enabled. We are already setting smart idle and L3 autogating
for GPMC clock in gpmc_init.
