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" * tag 'rtc-5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux: (63 commits) dt-bindings: rtc: at91rm9200: document clocks property rtc: i2c/spi: Avoid inclusion of REGMAP support when not needed rtc: Kconfig: select REGMAP_I2C when necessary rtc: Kconfig: properly indent sd3078 entry rtc: cmos: Refactor code by using the new dmi_get_bios_year() helper rtc: cmos: Use predefined value for RTC IRQ on legacy x86 rtc: cmos: Stop using shared IRQ rtc: tps6586x: Use IRQ_NOAUTOEN flag rtc: at91rm9200: use FIELD_PREP/FIELD_GET rtc: at91rm9200: avoid time readout in at91_rtc_setalarm rtc: at91rm9200: move register definitions to C file rtc: at91rm9200: add sama5d4 and sama5d2 compatibles dt-bindings: rtc: at91rm9200: convert bindings to json-schema rtc: at91rm9200: remove procfs information dt-bindings: atmel, at91rm9200-rtc: add microchip, sam9x60-rtc rtc: pcf8563: Use BIT rtc: moxart: Convert to SPDX identifier rtc: ds1343: Remove unused struct spi_device in struct ds1343_priv rtc: rx8025: Remove struct i2c_client from struct rx8025_data rtc: hym8563: Read the valid flag directly instead of caching it ...

-Atmel AT91RM9200 Real Time Clock
-
-Required properties:
-- compatible: should be: "atmel,at91rm9200-rtc" or "atmel,at91sam9x5-rtc"
-- reg: physical base address of the controller and length of memory mapped
- region.
-- interrupts: rtc alarm/event interrupt
-- clocks: phandle to input clock.
-
-Example:
-
-rtc@fffffe00 {
- compatible = "atmel,at91rm9200-rtc";
- reg = <0xfffffe00 0x100>;
- interrupts = <1 4 7>;
- clocks = <&clk32k>;
