[GIT PULL] LED updates for 4.19-rc1

[Jacek Anaszewski]

Hi Linus,

Please pull LED updates for 4.19-rc1.

LED triggers improvements make the biggest part of this pull request.
The most striking ones, that allowed for nice cleanups in the triggers are:
	- centralized handling of creation and removal of trigger sysfs
	  attributes via attribute group
        - addition of module_led_trigger() helper

The other things that need to be mentioned:

New features and improvements to existing LED class drivers:
	- lt3593: add DT support, switch to gpiod interface
	- lm3692x: support LED sync configuration, change OF calls to fwnode calls
	- apu: modify PC Engines apu/apu2 driver to support apu3

Change in the drivers/net/can/led.c:
	- mark led trigger as broken since it's in the way for the further
          cleanups. It implements a subset of the netdev trigger and an Ack
	  is needed from someone who can actually test and confirm that the netdev
	  trigger works for can devices.

Thanks,
Jacek Anaszewski
