[PATCH v3 0/4] dt-bindings: rtc: convert multiple devices to dtschema

[PATCH v3 0/4] dt-bindings: rtc: convert multiple devices to dtschema

[Javier Carrasco]

This series converts the following existing bindings to dtschema:

- armada-380-rtc
- alphascale,asm9260-rtc
- digicolor-rtc (moved to trivial-rtc)
- nxp,lpc1788-rtc

All bindings include at least one compatible that is referenced in the
existing dts (arch/arm). Those dts could be tested against the new
bindings.

It might be worth mentioning that the reference to nxp,lpc1788-rtc in
arch/arm/boot/dts/nxp/lpc/lpc18xx.dtsi also includes another compatible
called nxp,lpc1850-rtc, which is not documented or supported by existing
drivers. That generates a warning when testing against nxp,lpc1788-rtc.
