My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'

See https://patchwork.ozlabs.org/patch/1569828

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.

+      The prescaler divides the input frequency to create a time-based strobe (typically 1 Hz) for
+      the calendar counter. The Alarm and Compare Registers, in conjunction with the calendar
+      counter, facilitate time-matched events. To properly operate in Calendar or Binary mode,
+      the 26-bit prescaler must be programmed to generate a strobe to the RTC.
