[PATCH v5 0/2] PWM: PXA: add device tree support to PWM driver

[mikedunn@newsguy.com (Mike Dunn)]

This is now a patch set because the changes to pxa27x.dtsi have been moved to a
separate patch.  This was done so that it can go through the arm-soc tree.

Changle log:
v5:
- changes to pxa27x.dtsi moved to a separate patch
- minor changes in phrasing made to bindings documentation
- cast removed from void *
- dummy functions for !CONFIG_OF removed; called only if (IS_ENABLED(CONFIG_OF)
- if-else block in pxa_pwm_get_id_dt() replaced with ternary operator

v4:
- add second "compatible" string to pxa27x.dtsi
- change phrasing in binding doc pxa-pwm.txt to "one or more of"

v3:
- remove support for the polarity flag
- remove per-chip pwm index cell; define custom of_xlate()
   (now #pwm-cells = <1>)
- "compatible" strings for all devices added to OF match table
- various stylistic changes recommended by reviewers

v2:
- of_match_table contains only the "pxa250-pwm" compatible string; require one
  device instance per pwm
- add Documentation/devicetree/bindings/pwm/pxa-pwm.txt
- add support for polarity flag in DT and implement set_polarity() method
  (the treo 680 inverts the signal between pwm out and backlight)
- return -EINVAL instead of -ENODEV if platform data or DT node not found
- output dev_info string if platform data missing
- expanded CC list of patch
