Why did you drop this GPIO? Isn't this the GPIO that the RTC uses to wakeup the system? If so, this should be included as part of this patch. It probably still works because the bootloader configures this GPIO as input, but the kernel should not rely on the booloader for that, so please include as part of this patch. Other than that, this is looking OK. Curious how you're testing this? When I tested with rtcwake (from buildroot), I'm getting this: / # rtcwake -d rtc0 -m mem -s4 rtcwake: RTC_RD_TIME: Invalid argument Kevin
