[PATCH v3 0/4] rtc: convert multiple bindings into dtschema

[Javier Carrasco <javier.carrasco.cruz@gmail.com>]

This series converts the following bindings into dtschema, moving them
to trivial-rtc whenever possible:

- google,goldfish-rtc: trivial-rtc, referenced in mips arch.
- lpc32xx-rtc: trivial-rtc, referenced in arm arch.
- maxim,ds1742: trivial-rtc, not referenced in arch, cheap conversion.
- orion-rtc: trival-rtc, referenced in arm arch.
- pxa-rtc: add missing properties and convert. Referenced in arm arch.
- rtc-aspeed: 3 devices to trivial-rtc, all referenced in arm arch.
- st,spear600-rtc: trivial-rtc, referenced in arm arch.
- stmp3xxx-rtc: add compatibles and convert, referenced in arm arch.
- via,vt8500-rtc: trivial-rtc, referenced in arm arch.

The only reference to the lpc32xx RTC makes use of a 'clocks' property
that does not describe a controllable signal (it is in fact a fixed
32768 Hz crystal, the input clock of the SoC). Remove this property to
better describe the device and avoid errors when checking the dts
against the RTC binding.

Changes in v3:
- Fix typo in commit description (rtc-aspeed).
- Move lpc32xx-rtc to trivial-rtc again.
- Remove 'clocks' property from the rtc node in lpc32xx.dtsi.
- Link to v2: https://lore.kernel.org/r/20240410-rtc_dtschema-v2-0-d32a11ab0745 at gmail.com

Changes in v2:
- General: squash all moves to trivial-rtc into a single patch.
- MAINTAINERS: remove reference to google,goldfish-rtc.txt
- lpc32xx-rtc: create own binding to add the undocumented 'clocks'
  property.
- fsl,stmp3xxx-rtc.yaml: document missing compatibles.
- Link to v1: https://lore.kernel.org/r/20240408-rtc_dtschema-v1-0-c447542fc362 at gmail.com
