Merge tag 'rtc-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux

Pull RTC updates from Alexandre Belloni:
 "Subsystem wide cleanups:
   - Use IS_ENABLED() instead of checking for built-in or module
   - remove useless DRV_VERSION
   - remove CLK_IS_ROOT
   - remove UIE signaling

  Drivers:
   - ds1302: rewritten to be a proper SPI device driver
   - m41t80: huge cleanup, alarm, wakelarm ans oscialltor failure
     detection support
   - rv3029: switch to regmap to handle rv3049, alarm support, fixes
   - zynqmp: enable switching to battery power, fixes
   - small fixes for at91sam9, da9053, ds1307, ds1685, ds3232, r2025,
     sa1100, snvs, stmp3xxx, tps6586x"
