Subject: [PATCH 2/3] ARM: dts: imx6: change gpt per clk to gpt_3m on i.mx6qdl and i.mx6sx
Date: Wed, 3 Sep 2014 15:36:44 +0800	[thread overview]
Message-ID: <1409729805-9741-3-git-send-email-b20788@freescale.com> (raw)
In-Reply-To: <1409729805-9741-1-git-send-email-b20788-KZfg59tc24xl57MIdRCFDg@public.gmane.org>

Original gpt per clk parent is from ipg_per clk which
may be scaled when system enter low bus mode, as ipg
clk will be lower in low bus mode, to keep system clk
NOT drift, select gpt per clk parent from OSC which
is at fixed freq always.
