ARM: S3C2443/S3C2416: add s3c_rtc_setname and rename rtc
From: =?UTF-8?q?Heiko=20St=C3=BCbner?= <heiko@...> Date: Fri, 9 Dec 2011 10:51:38 +0100
Commit-Message
As the S3C24xx SoCs use the same rtc device a renaming capability like in the adc driver is necessary. This patch adds a s3c_rtc_setname function and names the rtc devices for S3C2443 and S3C2416 accordingly. Signed-off-by: Heiko Stuebner <heiko@...>
