Subject: [PATCH 3/7] Document: dt: fsl: snvs: change support syscon
Date: Fri, 15 May 2015 21:36:26 +0800	[thread overview]
Message-ID: <1431696990-23078-4-git-send-email-Frank.Li@freescale.com> (raw)
In-Reply-To: <1431696990-23078-1-git-send-email-Frank.Li@freescale.com>

From: Frank Li <Frank.Li@freescale.com>

snvs actually is multi fucntion driver.
Change to use syscon to access register.
