Merge tag 'rtc-4.6' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux

Pull RTC updates from Alexandre Belloni:
 "Core:
   - New sysfs interface to set and read clock offset
   - Drivers can now be both I2C and SPI (see pcf2127 and ds3232)

  New drivers:
   - Alphascale ASM9260
   - Epson RX6110SA
   - Maxim max20024 and max77620 (in max77686)
   - Microchip PIC32
   - NXP pcf2129 (in pcf2127)

  Subsystem wide cleanups:
   - remove IRQF_EARLY_RESUME when unecessary

  Drivers:
   - ds1307: clock output, temperature sensor and wakeup-source support
   - ds1685: actually spin forever in poweroff error path
   - ds3232: many cleanups
   - ds3234: merged in ds3232
   - hym8563: fix invalid year calculation
   - max77686: many cleanups
   - max77802 merged in max77686
   - pcf2123: cleanups and offset support
   - pcf85063: cleanups
   - pcf8523: propely handle oscillator stop bit
   - rv3029: many cleanups, trickle charger and temperature sensor support
   - rv8803: convert spin_lock to mutex_lock
   - rx8025: many fixes
   - vr41xx: restore alarm_irq_enable"
