Hello

For those I have added to this patchset this is a new LED framework that will
group monochrome LEDs into a directory under the parent LED class device. I have
CC'd you on this because you maintain a device tree file that contains one of
the devices affected by this change.  Most notably the change is to add the
reg property to each LED child node to denote the output channel that the node
is to use.  This not only is required for the Multicolor framework but also gives
flexibilty in DT design to be able to not be bound to sequential channel
numbering.

There are many changes from v8 to this patchset from Jacek's comments.
v8 series
https://lore.kernel.org/patchwork/project/lkml/list/?series=411331

Most notably
Removal of get/set_brightness ops
Dereferencing the monochrome LED intensity from the multicolor structure as
opposed to the ops.
Update for LP55xx DT properties to include the reg property to identify the
output channel for multicolor and non-multicolor use cases.  This also allows
HW designers to skip output channels if they desire.
Updated the corresponding affect device tree files to add the reg property
Checkpatch error fixes for the lp55xx common

These changes were tested using the LP50xx evms and LP5523 EVM connected to a
BeagleBone black device.
