Inherit PM660L PMIC LPG/triled block configuration from downstream
drivers and DT sources, consisting of a triled block with automatic
trickle charge control and source selection, three colored led channels
belonging to the synchronized triled block and one loose PWM channel.

When reviewing the Qualcomm SPMI PMIC bindings I noticed that this patch
was never picked up by the LEDs maintainer, while the binding and dtsi
changes made it in:

	https://lore.kernel.org/r/20220719211848.1653920-2-marijn.suijten@somainline.org

Looks like it may still apply cleanly, but otherwise, would you mind
rebasing and resending so that Lee can pick this one up?

Coincidentally I haven't touched this device/platform for months... until last
weekend where I noticed the same.  It does not apply cleanly and I had to solve
some conflicts:

https://github.com/SoMainline/linux/commit/8ec5d02eaffcec24fcab6a989ab117a5b72b96b6

I'll gladly resend this!

Note that I have one more unmerged leds patch around, that hasn't been looked
at either.  Would it help to send this once again, perhaps with more reviewers/
testing (Johan, would you mind taking a look too)?

https://lore.kernel.org/linux-leds/20220719213034.1664056-1-marijn.suijten@somainline.org/

Thanks!

Yes, I suggest you resend that one too so that it ends up in Lee's
inbox.

I will rebase, test and resend it too.  Just asking if you notice any glaring
issues with this patch, as it won't be the first time it has been resent after
not being looked at for some time.

I haven't look at this code before and only skimmed it now, but your
patch looks correct to me.

Apologies for taking more time than necessary.  According to b4 the patch should
become available at:

https://lore.kernel.org/r/20240204-pm660l-lpg-v5-1-2f54d1a0894b@somainline.org

I'll continue looking into clarifying this patch before resending it.
