Re: [PATCH 3/3] dt-bindings: rtc: ti,omap-rtc: Convert to DT schema

Thank you for your contribution! Sashiko AI review found 2 potential issue(=
s) to consider:
- [Low] The legacy text binding file `rtc-omap.txt` was not removed during =
the conversion to the new YAML DT schema.
- [Low] The schema unconditionally allows `system-power-controller` and `ex=
t-wakeup` properties for all hardware variants, lacking required conditiona=
l constraints.

dt-bindings: rtc: ti,omap-rtc: Convert to DT schema

Convert the Texas Instruments OMAP Real Time Clock (RTC) binding from
the legacy text format to the DT schema. Mark 'ti,hwmods' as deprecated
as it is no longer used, it is kept to support legacy boards.

[Severity: Low]
Should this conversion also delete the legacy text binding? It appears
Documentation/devicetree/bindings/rtc/rtc-omap.txt was left in the tree,
which leaves duplicate binding documentation.

[Severity: Low]
Does this schema unconditionally allow system-power-controller for all
hardware variants?

For instance, the ti,da830-rtc variant doesn't appear to support PMIC mode.
Should there be an allOf / if-then block restricting this property to
ti,am3352-rtc and ti,am4372-rtc?

[Severity: Low]
Similar to the system-power-controller property, should this subnode also be
restricted to variants that support it?=20

Without an allOf / if-then block, it seems device trees configured with
ext-wakeup for older hardware like ti,da830-rtc will silently pass schema
validation.
