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.

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 driver only supports gpio-attached LEDs on apu1/2/3 boards,
but neither gpio's themselves, nor other gpio-attached devices
(eg. front button).
For apu2+ a newer, more complete driver exists, based on a generic
driver for the AMD SOCs gpio-controller, supporting LEDs as well
other devices. Therefore these boards don't need legacy support
from this driver anymore.
Both drivers claim the same device, so only one driver may exist
in a system, putting distros in the position to decide between
either apu2+ keys or apu1 led support.
Therefore drop the apu2+ led support from the old driver, solve
the conflict and reduce unnecessary code.

Introduce the Texas Instruments LM3532 White LED driver.
The driver supports ALS configurability or manual brightness
control.
The driver also supports associating LED strings with specific
control banks in a group or as individually controlled strings.

The only user of this driver in mainline has now moved to DTS, so the pdata
code is no longer in use by anyone. Let's drop some dead code, and make the
driver depend on CONFIG_OF.

AN30259A is a 3-channel LED driver which uses I2C. It supports timed
operation via an internal PWM clock, and variable brightness. This
driver offers support for basic hardware-based blinking and brightness
control.

PC Engines apu3 is an improved version of the apu2, using the same SoC
and almost everything else.
This patch reuses as much as possible from the apu2 definitions, to
avoid redundancy.

Introduce the family of LED devices that can
drive a torch, strobe or IR LED.
The LED driver can be configured with a strobe
timer to execute a strobe flash. The IR LED
brightness is controlled via the torch brightness
register.

LED drivers can be found here:

Driver obtains LED devices according to system configuration and creates
devices in form: "devicename:color:function", like
The full path is to be:
/sys/class/leds/mlxreg\:status\:amber/brightness
After timer trigger activation:
echo timer > /sys/class/leds/mlxreg\:status\:amber/trigger
Attributes for LED blinking will appaer in sysfs infrastructure:
/sys/class/leds/mlxreg\:status\:amber/delay_off
/sys/class/leds/mlxreg\:status\:amber/delay_on
LED setting is controlled through the on-board programmable devices,
which exports its register map. This device could be attached to any
bus type, for which register mapping is supported.

Update the driver to conform with the LED framework:
- use devm_led_classdev_register
- destroy mutex on exit
- remove dependency on CONFIG_OF in the driver and move
to the Kconfig
- update the MODULE_LICENSE to GPL v2
- remove setting of MAX brightness as the LED framework
does this.
