Subject: [PATCH 3/3] rtc: stmp3xxx: use global stmp_device functionality
Date: Wed, 16 Nov 2011 11:47:39 +0100	[thread overview]
Message-ID: <1321440459-4527-4-git-send-email-w.sang@pengutronix.de> (raw)
In-Reply-To: <1321440459-4527-1-git-send-email-w.sang@pengutronix.de>

The former mach specific reset_block function has been converted to a global
one. Use the new one to remove mach dependency from the driver. Also simplify
code using the new STMP_REG_* macros.

Signed-off-by: Wolfram Sang <w.sang@pengutronix.de>
