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 fixes the driver and takes the opportunity to update the
dt-bindings accordingly.

v1: based on v5.9-rc2, backport on v5.4.59 tested and working

v2: based on v5.9-rc3, added the dt-bindings update patch

For both patches:

Acked-by: Jacek Anaszewski <jacek.anaszewski@xxxxxxxxx>

I'd like to make a v3 and change the license of the .yaml file to "(GPL-2.0-
only OR BSD-2-Clause)" as suggested by checkpatch and [1]. Can I keep your
Acked-by for that?

Go ahead.

Besides: those suggestions are obviously valid for new bindings. What about
old bindings (.txt), which had no explicit SPDX tag or license note before?
What license would apply there? Is the .yaml file technically new, when it
was mostly just converted from .txt?

I don't know what was the rationale behind adding license to
DT bindings, probably Rob will be able to share some details.

Possibly the fact that DT examples can be now compile-tested
makes some difference here.
