This series converts the Texas Instruments OMAP Real Time Clock (RTC)
binding from the legacy format to dt-schema.
The am3352-rtc is compatible with the da830-trc. Update the compatible
string to include the ti,da830-rtc fallback
Two legacy, undocumented properties were discovered in the upstream
device trees:
- 'ext-clk-src' in am57xx-idk-common.dtsi
- 'ti,no-init' in am335x-shc.dts
Both properties are completely unhandled by the rtc-omap driver. Patches
1 and 2 remove them from the device trees. Patch 3 then introduces the
new YAML schema.

Changes in v3:
- fixed dts where only am3352-rtc was used without da830-rtc
- fixed compatible where am3352 is only compatible with da830
- simplified clock-output-names property and pins property
- Link to v2: https://lore.kernel.org/r/20260725-ti-omap-rtc-v2-0-13f765ca96b3@gmail.com
Changes in v2:
- Patch 1: unchanged
- Patch 2: unchanged
- Patch 3: Removed left out legacy text binding and Added constraint
block restricting 'system-power-controller' and 'ext-wakeup' subnodes
strictly to hardware variants that support PMIC mode
