[PATCH v2 0/4] Add PWM polarity flag macro for DT

Hello,

Here's a small patch set that replaces PWM polarity numerical constants with
macros in DT.

The series is the result of splitting the original patch into four patches
that

- add the flag macro (both in a header file and in the PWM DT binding core
  documentation)
- use the macro in the PWM core code
- update existing DT bindings to refer to the PWM DT bindings core
  documentation
- update existing DT sources to use the new macro

I believe I've taken all comments received so far into account. Most notable
changes include

- splitting the original patch
- removing the PWM_POLARITY_NORMAL flag, which wasn't a flag but was defined
  as 0
- renaming the PWM_POLARITY_INVERSED DT flag to PWM_POLARITY_INVERTED
- not relying on DT flags and PWM C flags having identical names and values

Laurent Pinchart (4):
  pwm: Add PWM polarity flag macro for DT
  pwm: Use the DT macro directly when parsing PWM DT flags
  pwm: Update DT bindings to reference pwm.txt for cells documentation
  ARM: dts: Use the PWM polarity flags
