[GIT PULL] RTC for 5.6
From: Alexandre Belloni
Date: Mon Feb 03 2020 - 17:32:48 EST
Hello Linus,
Here is the pull-request for the RTC subsystem for 5.6.
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.
The following changes since commit e42617b825f8073569da76dc4510bfa019b1c35a:
Linux 5.5-rc1 (2019-12-08 14:57:55 -0800)

RTC for 5.6
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
