[PATCH 2/4] leds: qcom-lpg: Add PM660L configuration and compatible

[Marijn Suijten]

Inherit PM660L PMIC LPG/triled block configuration from downstream

[PATCH 3/4] arm64: dts: qcom: pm660l: Add LPG node

[Marijn Suijten]

The Light Pulse Generator describes a hardware block responsible for
displaying colors and patterns on an RGB LED (usually used for [battery]
status and notifications), and drive PWM signals for general-purpose
(ie. backlight) LEDs.  The availability and usage of the individual
channels differ per board and is hence left for individual platform DTs
to configure.

Bjorn's patches got pulled into Pavel's linux-leds tree just yesterday:

    https://git.kernel.org/pub/scm/linux/kernel/git/pavel/linux-leds.git/log/?h=for-next

Specifically, this file got added in:

    https://git.kernel.org/pub/scm/linux/kernel/git/pavel/linux-leds.git/commit/?h=for-next&id=a8e53db46f19f67be6a26488aafb7d10c78e33bd

They don't seem to be in next-20220504 yet either, but should probably
show up in next-20220505.  This shouldn't prevent the patch from being
picked up for linux-leds though, now that everone is scrambling to send
additional LPG configs in hopes of landing for 5.19 all at once.

Thank you, but I could not apply it. Can you collect reviews and
resend? I'll only be able to apply first two.

Thank you for notifying me.  It seems the diff-context changed a little
when the pm8350c-pwm patches were applied, the series is now rebased on
linux-leds and re-sent as [1] (I may have forgotten to pass -v2 to git
format-patch, apologies for that).

> Can you collect reviews

Unless I missed something there only seems to be one Acked-by from Rob,
on the dt-bindings patch - I hope that's enough and otherwise Bjorn may
want to chime in on the LPG code part.

> I'll only be able to apply first two.

No worries about that, I expect Bjorn to pick up the latter two through
the arm-msm tree.  Is it okay if I send all patches as a unified series
going forward, or should it rather be split per sub-tree/maintainer?

Last but not least, a friendly reminder to look at patch [2] (resent as
[3]) to complement Bjorn's LPG patches.
