Re: [PATCH v23 02/16] leds: multicolor: Introduce a multicolor class definition

Dan,
I've converted drivers/leds/leds-an30259a.c to LED mc framework
and tested it on Samsung Galaxy S3 (exysnos4412-trats2 board).
Works as expected. And now the framework usability is indeed neater.
One thing to improve: LED mc based drivers' entries in Kconfig should 
have this dependency:
depends on LEDS_CLASS_MULTI_COLOR || !LEDS_CLASS_MULTI_COLOR
It is required to enforce building driver as a module if
LED mc framework is configured as such.
With this (and DT bindings nits) addressed, for patches 1-6:

It's been a long journey. Thank you for your determination to drive
this work to the end.
Best regards,
Jacek Anaszewski

Introduce a multicolor class that groups colored LEDs
within a LED node.
The multi color class groups monochrome LEDs and allows controlling two
aspects of the final combined color: hue and lightness. The former is
controlled via the intensity file and the latter is controlled
via brightness file.
