Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] The subnode for the LED under `pwm-leds` is named `status`, which violates the `leds-pwm` device tree binding schema.

arm64: dts: amlogic: t7: khadas-vim4: add PWM-driven status LED

This commit enables the pwm_ao_cd controller and adds a pwm-leds node with a
heartbeat trigger to expose the status LED on the VIM4 board.

Does this subnode name trigger a device tree schema validation error?

The leds-pwm binding schema in
Documentation/devicetree/bindings/leds/leds-pwm.yaml specifies
additionalProperties: false and expects child node names to match the
regular expression ^led(-[0-9a-f]+)?$.

Using status as a node name is also confusing since it is commonly used as a
standard device tree property.

Should this be renamed to something like led-status or led-0 to comply with
the schema?
