Pull LED updates from Pavel Machek:
 "Besides the usual fixes and new drivers, we are changing CLASS_FLASH
  to return success to make it easier to work with V4L2 stuff disabled,
  and we are getting rid of enum that should have been plain integer
  long time ago. I'm slightly nervous about potential warnings, but it
  needed to be fixed at some point"

Parallel to serial conversion, which is also called SSO controller,
can drive external shift register for LED outputs, reset or
general purpose outputs.

This driver enables LED support for Serial Shift Output Controller (SSO).

This adds a driver for the Richtek RT8515 dual channel
torch/flash white LED driver.

This LED driver is found in some mobile phones from
Samsung such as the GT-S7710 and GT-I8190.

A V4L interface is added.

We do not have a proper datasheet for the RT8515 but
it turns out that RT9387A has a public datasheet and
is essentially the same chip. We designed the driver
in accordance with this datasheet. The day someone
needs to drive a RT9387A this driver can probably
easily be augmented to handle that chip too.

Sakari Ailus, Pavel Machek and Andy Shevchenko helped
significantly in getting this driver right.

Acer Iconia Tab A500 is an Android tablet device which has two LEDs
embedded into the Power Button. Orange LED indicates "battery charging"
status and white LED indicates "wake-up/charge-done" status. The new LED
driver provides control over both LEDs to userspace.

Introduce the LP5036/30/24/18/12/9 RGB LED driver.
The difference in these parts are the number of
LED outputs where the:

LP5036 can control 36 LEDs
LP5030 can control 30 LEDs
LP5024 can control 24 LEDs
LP5018 can control 18 LEDs
LP5012 can control 12 LEDs
LP5009 can control 9 LEDs

The device has the ability to group LED outputs into control banks
so that multiple LED banks can be controlled with the same mixing and
brightness. Or the LED outputs can also be controlled independently.

This adds basic support for LEDs on the front side of CZ.NIC's Turris
Omnia router.

There are 12 RGB LEDs. The controller supports HW triggering mode for
the LEDs, but this driver does not support it yet, and sets all the LEDs
defined in device-tree into SW mode upon probe.

This driver uses the multicolor LED framework.

Introduce a multicolor class that groups colored LEDs
within a LED node.

The multicolor 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.

Add a driver for the SGMICRO SGM3140 Buck/Boost Charge Pump LED driver.

This device is controlled by two GPIO pins, one for enabling and the
second one for switching between torch and flash mode.
