[sashiko-bot@kernel.org]

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Medium] The `#pwm-cells` property is defined but omitted from the `required` list in the device tree binding, violating subsystem guidelines for hardware with provider capabilities.

dt-bindings: hwmon: add adi,adt7470

This commit adds the device tree binding documentation for the Analog Devices
ADT7470 multichannel temperature sensor and PWM fan controller. It defines
support for the thermal framework and models fan control lines as PWM
channels.

[Severity: Medium]
Should "#pwm-cells" be included in this required list?

When a hardware variant has provider capabilities like a PWM output, the
corresponding properties are typically expected to be present in the required
list. Without it, incomplete device tree nodes lacking the "#pwm-cells"
property might pass schema validation but fail at runtime when dependent
subsystems attempt to use the device as a PWM provider.
