Subject: [PATCH 2/8] ARM/Samsung: adapt the generic timer driver to support the S3C6410 SoC
Date: Sat, 21 Jul 2012 12:04:27 +0200	[thread overview]
Message-ID: <1342865073-5209-3-git-send-email-jbe@pengutronix.de> (raw)
In-Reply-To: <1342865073-5209-1-git-send-email-jbe@pengutronix.de>

The S3C64XX SoC has a real 32 bit counter, but almost the same style of
registers. It's enough to change the parameters, to get the routines work on
this SoC.

TODO: what about the S5P SoCs?
