Use the mtk_pwm_data struction to define different registers
and add MT8183 specific register operations, such as MT8183
doesn't have commit register, needs to disable double buffer
before writing register, and needs to select commit mode
and use PWM_PERIOD/PWM_HIGH_WIDTH.

There is no difference compared to (implicit) v1 sent a few minutes
earlier, right? There was another patch sent with the same Subject last
week, so I assume the mail from today without "v2" in the Subject was a
mistake?

Adding a paragraph below the tripple dash that points out what was
changed compared to the previous submission is a good idea to help
reviewers to more easily see what was changed. I guess you only adapted
the commit log as a reaction to Matthias Burgger's review?

Best regards
Uwe

Yes, I miss the "V2" and fine tune the commit message.
