[PATCH] dt-bindings: rtc: isl12026: convert to YAML schema

[Piyush Patle]

Convert the ISL12026 RTC binding to DT schema format.

The binding was previously documented in text format.
This converts it to YAML and enables dtbs_check validation.

+  The RTC and control registers respond at address 0x6f, while the EEPROM
+  array responds at address 0x57. The "reg" property refers to the RTC
+  portion of the device.

Best regards,

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:
./Documentation/devicetree/bindings/rtc/isil,isl12026.yaml:4:6: [error] string value is redundantly quoted with any quotes (quoted-strings)

doc reference errors (make refcheckdocs):

See https://patchwork.kernel.org/project/devicetree/patch/20260218190213.429892-1-piyushpatle228@gmail.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

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 after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
