However, rtc wake support on OMAP1 is broken. Hence the device_init_wakeup() was removed from rtc-omap driver and moved to platform board files that supported it (DA850/OMAP-L138). [1] However, recently [2] it was suggested that driver should always do a device_init_wakeup(dev, true). Platforms that don't want/need wakeup support can disable it from userspace via: echo disabled > /sys/devices/.../power/wakeup Also, with the new DT boot-up, board file doesn't exist and hence there is no way to have device wakeup support rtc. The fix for above issues, is to hard code device_init_wakeup() inside driver and let platforms that don't need this, handle it through the sysfs power entry. Also, update Davinci & AM335x files to above changes.
