[v6,0/7] leds: pwm: Make automatic labels work

Message

Alexander Dahl Sept. 30, 2020, 11:46 p.m. UTC

Hei hei,

for leds-gpio you can use the properties 'function' and 'color' in the
devicetree node and omit 'label', the label is constructed
automatically.  This is a common feature supposed to be working for all
LED drivers.  However it did not yet work for the 'leds-pwm' driver.

This series removes platform_data support for the leds-pwm driver and
takes the opportunity to update the leds-pwm dt-bindings accordingly.

After myself being one week on vacation patch 2/3 was already picked by
Pavel and I gathered some more feedback on the remaining issues.

v6 was compile tested and dt_bindings_check and dtbs_check were run.

Note: I added some patches to fix DT schema warnings, but I did not put
every reviewer/supporter/maintainer printed by get_maintainers in Cc to
keep that list reasonable small.

Series changelog below …
