Merge tag 'rtc-4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux

Pull RTC updates from Alexandre Belloni:
 "Subsystem:
   - remove .open() and .release() RTC ops
   - constify i2c_device_id

  New driver:
   - Realtek RTD1295
   - Android emulator (goldfish) RTC

  Drivers:
   - ds1307: Beginning of a huge cleanup
   - s35390a: handle invalid RTC time
   - sun6i: external oscillator gate support"
