[Axel Lin]

The implementation of .config(), .enable() and .disable() operations in this
driver may sleep, thus set pwm_chip can_sleep flag.

@Thierry,

There are still 4 patches before this one, and I'd like to know the status of
them: 
	[PATCHv2 0/4] FTM PWM adds regmap and endianness support.

Thanks,

I was holding off on those because I thought I had seen some discussion
about how to represent endianness support in DT and I'm not aware that
there were any conclusions yet.

  pwm: ftm-pwm: Clean up the code.
  pwm: ftm-pwm: Convert to direct regmap API usage.

Well, how about the above two patches? And that discussion is mostly about 
The following ones:

  Documentation: Add 'big-endian' property for FTM PWM.
  pwm: ftm-pwm: Add big-endian support
