If that is indeed the case and you always have either starfive,jh7100-pwm or starfive,jh7110-pwm, you can drop the logic to only use starfive_jh71x0_get_ch_base conditionally. Best regards Uwe

And I need to add the starfive_jh71x0_get_ch_base to compatibility with jh71x0. So even the "opencores,pwm-v1" isn't a valid configuration, but I still need to add it for OpenCores.

This is also meant to be an Ack from me. I imagined the dt patches would go through Conor's riscv-dt-for-next branch, but the pwm tree is certainly also fine by. /Emil

I suppose I could take the binding though, since I am CCed on every binding patch under the sun... I'd rather an explicit ack in that case though. Cheers, Conor.
