[PATCH v3 0/2] leds: rgb: lpg: Don't enable TRILED when configuring PWM

[Fenglin Wu via B4 Relay <devnull+fenglin.wu.oss.qualcomm.com@kernel.org>]

The LPG channel can be used for only outputting PWM signal without the
need to enable TRILED. Update the DT binding document to explain that
usage and remove the TRILED enabling register write in the driver for
that use case.

Changes in v3:
- Add a DT binding change to clarify the standalone PWM usage according
  to the suggestion from Bjorn.
- Link to v2: https://lore.kernel.org/r/20251118-lpg_triled_fix-v2-1-6d1e5831333f@oss.qualcomm.com

Changes in v2:
- Check "chan->in_use" flag in lpg_pwm_apply() is not correct, as it
  indicates the channel is being used as a LED and this PWM API would
  never get called. Instead, remove the code line which enables TRILED
  in lpg_pwm_apply() and update the commit text to explain it clearly.
