Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Medium] The devicetree binding schema misses standard fan cooling properties (`#cooling-cells` and `cooling-levels`), breaking thermal zone integration.

dt-bindings: hwmon: add Axiado AX3000 and AX3005 PWM fan controller

This commit adds a devicetree binding for the PWM fan controller on Axiado
AX3000 and AX3005 SoCs, which uses a hardware tachometer and external PWM
controller. It also updates the MAINTAINERS file.

[Severity: Medium]
Does this strict property check prevent thermal zone integration? 

Setting additionalProperties to false without a reference to fan-common.yaml#
or explicitly allowing #cooling-cells and cooling-levels will cause schema
validation to fail if standard fan cooling properties are added. 

A devicetree node attempting to integrate this fan controller into a thermal
cooling-maps block will fail dtbs_check with a 'node has property not allowed
by schema' error.
