Merge tag 'rtc-5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux

Pull RTC updates from Alexandre Belloni:
 "The VL_READ and VL_CLR ioctls have been reworked to be more useful.
  This will not break userspace as there are very few users and they are
  using the integer value as a boolean.

  Apart from that, two drivers were reworked and a few fixes here and
  there for a net reduction of number of lines.

  Summary:

  Subsystem:
   - the VL_READ and VL_CLR ioctls are now documented and their behavior
     is unified across all the drivers.
   - RTC_I2C_AND_SPI Kconfig option rework to avoid selecting both
     REGMAP_I2C and REGMAP_SPI unecessarily.

  Drivers:
   - at91rm9200: remove deprecated procfs, add sam9x60, sama5d4 and
     sama5d2 compatibles.
   - cmos: solve lost interrupts issue on MS Surface 3
   - hym8563: return proper errno when time is invalid
   - rv3029: many fixes, nvram support"
