* rtc: Fix module autoload for OF platform driversJavier Martinez Canillas2015-09-051-0/+1
| | | | | | | | | These platform drivers have a OF device ID table but the OF module alias information is not created so module autoloading won't work.

* rtc: mt6397: enable wakeup before registering rtc deviceWei-Ning Huang2015-07-181-2/+2
| | | | | | | | | | rtc_sysfs_add_device checks if device can wakeup before creating the wakealarm file in sysfs. Thus the driver must set wakeup capability before registering the rtc device.

* rtc: mt6397: fix build on some 32bits platformsAlexandre Belloni2015-06-251-2/+3
| | | | | | | | | | | | | | | On some !ARM 32bits platforms, the following compilation error happens because of the division on a 64bits value in mtk_rtc_read_time(): drivers/built-in.o: In function `mtk_rtc_read_time': rtc-mt6397.c:(.text+0x265d13f): undefined reference to `__divdi3' rtc-mt6397.c:(.text+0x265d150): undefined reference to `__moddi3' Use div_s64() as done in rtc_time64_to_tm() to solve that.
