Sorry for the OCD, but I would really like for you to capitalize 's' and
'p' in your name.

As you might have seen in v12 I dropped pwm_9bit_mask.

Afaict there's a tri-channel current sink in pm8350c as well, so you
should have:

        .triled_base = 0xef00,

And then associated .triled_mask in the relevant channels.
