Notable changes:
- ROM child nodes use dashes instead of underscores; the driver
  reads all child nodes regardless of their names, so this doesn't
  break ABI.
- pwm-period argument is deprecated, as it effectively duplicates
  the period value provided in pwms. The driver continues to accept
  the property, so this should not break ABI.
