If this is multi-led, then you should reference
/schemas/leds/leds-pwm-multicolor.yaml

See other examples using it.

In my opinion, leds-pwm-multicolor.yaml is used for external pwm
signals, and needs to assign an external pwm property.
But our pwm leds use an internal clock to generate the pwm signal. Is
leds-class-multicolor.yaml more appropriate?

Yeah, I meant the latter but pasted wrong file.
/schemas/leds/leds-class-multicolor.yaml#
