This addresses all of the issues in driver/pwm

Let me know if you want any of the individual module changes
segregated into separate patches.

Looks good to me, I applied it to
https://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux.git pwm/for-next

MediaTek SoCs have got two different PWM IPs, one of which is used exclusively
for the Display PWM, and it is located in the DDP block.

So, there are two PWM IPs in one SoC:
  - A general purpose PWM IP
  - A DDP PWM IP

This driver is for the general purpose PWM IP.. so, please, can we change this
to "MediaTek general purpose Pulse Width Modulator driver"?

After which,

Looks like a reasonable request.

@Jeff: Can you please resend with the suggested change, I dropped the
patch from for-next now.
