Subject: [PATCH 02/21] ARM: s3c: remove s3c24xx specific hacks
From: Arnd Bergmann <arnd@...db.de>
A number of device drivers reference CONFIG_ARM_S3C24XX_CPUFREQ or
similar symbols that are no longer available with the platform gone,
though the drivers themselves are still used on newer platforms,
so remove these hacks.
Signed-off-by: Arnd Bergmann <arnd@...db.de>

interrupt rates from 1Hz to 64Hz for user programs, and
wakeup from Alarm.
- The driver currently supports the common features on all the

This driver can also be build as a module. If so, the module
will be called rtc-s3c.
