Subject: [PATCH 1/4] ARM: i.MX53: Fix pll216 setup
Date: Wed,  3 Apr 2013 09:09:37 +0200	[thread overview]
Message-ID: <1364972980-32527-2-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1364972980-32527-1-git-send-email-s.hauer@pengutronix.de>

The value for i.MX53 216MHz is actually 432MHz. Use the same value
as for i.MX51 which really corresponds to 216MHz. These are the same
PLL216 values as U-Boot uses.
