[PATCH 3/3] rtc: Disable RTC_DRV_CMOS on Atari

From: Geert Uytterhoeven
Date: Sun Dec 08 2013 - 04:50:51 EST


On ARAnyM (emulating an Atari Falcon, which doesn't have an RTC IRQ, as the
Second Multi Function Peripheral MFP 68901 is available on Atari TT only),
rtc-cmos doesn't work well:
- The date is of by 32 years (2045 instead of 2013):

rtc_cmos rtc_cmos: setting system clock to 2045-12-02 10:56:17 UTC (2395824977)

- The hwclock utility doesn't work:

hwclock: ioctl() to /dev/rtc to turn on update interrupts failed unexpectedly, errno=5: Input/output error.

As rtc-generic works fine for the RTC part, and nvram works for the NVRAM
part, we'll continue on using that.
