PCF2127 is an SPI device, thus its binding should reference
spi-peripheral-props.yaml.

Add a reference to spi-peripheral-props.yaml to fix the following
dt-schema warning:

imx7d-flex-concentrator.dtb: rtc@0: 'spi-max-frequency' does not match any of the regexes: 'pinctrl-[0-9]+'

Qualcomm x1e80100 firmware sets the ownership of the RTC alarm to ADSP.
Thus writing to RTC alarm registers and receiving alarm interrupts is not
possible.

Add a qcom,no-alarm flag to support RTC on this platform.

imx31.dtsi uses the following RTC compatible:

compatible = "fsl,imx31-rtc", "fsl,imx21-rtc";

Document 'fsl,imx31-rtc' to fix the following dt-schema warning:

'fsl,imx31-rtc' is not one of ['fsl,imx1-rtc', 'fsl,imx21-rtc']

Convert the Spreadtrum SC27xx PMIC bindings to DT schema. Adjust the
filename to match the compatible of the only in-tree user, SC2731.
Change #interrupt-cells value to 1, as according to [1] that is the
correct value.
Move partial examples of child nodes in the child node schemas to this new
MFD schema to have one complete example.

just add its name and use the R329 as a fallback.

Lewis hasn't worked at Microchip for a while, and IIRC never actually
worked on the RTC in the first place. Remove him from the maintainers
list in the binding, leaving Daire.

Document the RTC IP (RTCA-3) available on the Renesas RZ/G3S SoC.
The RTC IP available on Renesas RZ/V2H is almost identical with the
one found on Renesas RZ/G3S (it misses the time capture functionality
which is not yet implemented on proposed driver). For this, added also a
generic compatible that will be used at the moment as fallback for both
RZ/G3S and RZ/V2H.
