This patch adds the 'mediatek,alarm-sta-supported' property to the RTC
node in the MediaTek MT6359 device tree source file. This property
indicates that the RTC supports alarm status functionality, which is
essential for proper power management and wake-up events.

Please do not use "This commit/patch/change", but imperative mood. See

NAK, there is no such ABI.

Test your code BEFORE you send it.

It does not look like you tested the DTS against bindings. Please run
`make dtbs_check W=1` (see
Documentation/devicetree/bindings/writing-schema.rst or
https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/
for instructions).
Maybe you need to update your dtschema and yamllint. Don't rely on
distro packages for dtschema and be sure you are using the latest
released dtschema.


Best regards,
Krzysztof

Dir sir,
  Thanks for comments; I will check the DTS file again according to the
method you posted. It will be revised in the next version.
