This series converts the following existing bindings to dtschema:
- armada-380-rtc
- alphascale,asm9260
- 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.

If there is going to be any resend, drop description. It is redundant
and obvious. reg cannot be anything else.
