Pull LED updates from Jacek Anaszewski:

 - userspace LED class driver - it can be useful for testing triggers
   and can also be used to implement virtual LEDs

 - LED class driver for NIC78bx device

 - LED core fixes for preventing potential races while setting
   brightness when software blinking is enabled

 - improvements in LED documentation to mention semantics on changing
   brightness while trigger is active

@@ -7,6 +7,9 @@ Optional properties:
- nxp,totem-pole : use totem pole (push-pull) instead of open-drain (pca9632 defaults
to open-drain, newer chips to totem pole)
- nxp,hw-blink : use hardware blinking instead of software blinking
- nxp,period-scale : In some configurations, the chip blinks faster than expected.
This parameter provides a scaling ratio (fixed point, decimal divided
by 1000) to compensate, e.g. 1300=1.3x and 750=0.75x.
Each led is represented as a sub-node of the nxp,pca963x device.
