v2 cover 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

Don't redefine a PWM_SPEC_POLARITY macro with a value identical to PWM_POLARITY_INVERTED, use the PWM DT macro directly.

PATCH v2 3/4 pwm: Update DT bindings to reference pwm.txt for cells documentation

The PWM client cells format is documented in the generic pwm.txt documentation and duplicated in all PWM driver bindings. Remove duplicate information and reference pwm.txt instead.

Reviewed-by Stephen Warren <[email protected]>

I'm (very very) slightly hesitant about patch 3/4, since it's moving towards all PWMs having to use the same specifier format, whereas specifiers are at least potentially binding-specific, not device-type-specific. However, consistency is good; there's no need to do something different just for the heck of it. Equally, there's nothing actually stopping a new binding from defining its own format rather than simply deferring to pwm.txt if it absolutely has to, so I think this will turn out fine.

Exactly, that's why I don't think it's an issue. pwm.txt defines a common format, individual bindings are free to use it or not.

v2 cover Add PWM polarity flag macro for DT

In reply to Laurent Pinchart
Quoted 41 lines · Laurent Pinchart

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: Use the DT macro directly when parsing PWM DT flags
