REGMAP is a hidden (not user visible) symbol. Users cannot set it
directly thru "make *config", so drivers should select it instead of
depending on it if they need it.
Consistently using "select" or "depends on" can also help reduce
Kconfig circular dependency issues.
Therefore, change the use of "depends on REGMAP" to "select REGMAP".

The Light Pulse Generator (LPG) is a PWM-block found in a wide range of
PMICs from Qualcomm. These PMICs typically comes with 1-8 LPG instances,
with their output being routed to various other components, such as
current sinks or GPIOs.
Each LPG instance can operate on fixed parameters or based on a shared
lookup-table, altering the duty cycle over time. This provides the means
for hardware assisted transitions of LED brightness.
A typical use case for the fixed parameter mode is to drive a PWM
backlight control signal, the driver therefor allows each LPG instance
to be exposed to the kernel either through the LED framework or the PWM
framework.
A typical use case for the LED configuration is to drive RGB LEDs in
smartphones etc, for which the driver supports multiple channels to be
ganged up to a MULTICOLOR LED. In this configuration the pattern
generators will be synchronized, to allow for multi-color patterns.
The idea of modelling this as a LED driver ontop of a PWM driver was
considered, but setting the properties related to patterns does not fit
in the PWM API. Similarly the idea of just duplicating the lower bits in
a PWM and LED driver separately was considered, but this would not allow
the PWM channels and LEDs to be configured on a per-board basis. The
driver implements the more complex LED interface, and provides a PWM
interface on the side of that, in the same driver.

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.

Update the Kconfig to be consistent in the case of using
"LED" in the Kconfig. LED is an acronym and should be
capitalized.

Since commit ebc278f15759 ("ARM: mvebu: remove static LED setup for
netxbig boards"), no one in upstream passes in the platform data to
this driver.
Squash leds-kirkwood-netxbig.h into the driver, and remove the legacy
board-file support.

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 LM36274 LED driver. This driver uses the ti-lmu
MFD driver to probe this LED driver. The driver configures only the
LED registers and enables the outputs according to the config file.
The driver utilizes the TI LMU (Lighting Management Unit) LED common
framework to set the brightness bits.

Create a TI LMU common framework for TI LMU devices that share
common features.
Currently the runtime ramp and brightness setting have
been identified as common features with common register settings.
This work is derived from Milo Kims TI LMU MFD code.
