leds: Add LED1202 I2C driver

The output current can be adjusted separately for each channel by 8-bit
analog (current sink input) and 12-bit digital (PWM) dimming control. The
LED1202 implements 12 low-side current generators with independent dimming
control.
Internal volatile memory allows the user to store up to 8 different patterns,
each pattern is a particular output configuration in terms of PWM
duty-cycle (on 4096 steps). Analog dimming (on 256 steps) is per channel but
common to all patterns. Each device tree LED node will have a corresponding
entry in /sys/class/leds with the label name. The brightness property
corresponds to the per channel analog dimming, while the patterns[1-8] to the
PWM dimming control.

leds: leds-lp5569: Add support for Texas Instruments LP5569

Add support for Texas Instruments LP5569 LED driver.

Texas Instruments LP5569 is 9 channels chip with programmable engines.

It almost a copy of LP5523 with fundamental changes to regs order and
regs content.

Has difference in how the clock is handled and doesn't support detecting
clock time automatically, different handling for selftest and different
scheme for the status regs.

LED chip supports ENGINE and MUX to group LED and run precompiled code
with magic values to run patterns. This is loaded via the sysfs entry
and it's passed as a string of ASCII HEX char.

One some devices using this LED Controller (a NBG7815 Router) it was
found loading big precompiled pattern with up to 96 bytes of code. To
have support for this "extended" scenario, hardcode each engine to
support 4 pages of precompiled pattern (128 bytes of code) and 1 page
for each MUX. This gives plenty of space for any kind precompiled
pattern keeping simple logic for page handling of each engine and mux.

leds: Introduce ExpressWire library

The ExpressWire protocol is shared between at least KTD2692 and KTD2801
with slight differences such as timings and the former not having a
defined set of pulses for enabling the protocol (possibly because it
does not support PWM unlike KTD2801). Despite these differences the
ExpressWire handling code can be shared between the two, so in
preparation for adding KTD2801 support introduce a library implementing
this protocol.

leds: Add Intel Cherry Trail Whiskey Cove PMIC LED driver

Add support for LEDs connected to the Intel Cherry Trail Whiskey Cove
PMIC. Charger and general-purpose LEDs are supported. Hardware blinking
is implemented, breathing is not.

This driver was tested with Lenovo Yoga Book notebook.

Changes by Hans de Goede (in response to review of v2):
- Since the PMIC is connected to the battery any changes we make to
the LED settings are permanent, even surviving reboot / poweroff.
Save LED1 register settings on probe() and if auto-/hw-control was
enabled on probe() restore the settings on remove() and shutdown().
- Delay switching LED1 to software control mode to first brightness write.
- Use dynamically allocated drvdata instead of a global drvdata variable.
- Ensure the LED is on when activating blinking.
- Fix CHT_WC_LED_EFF_BREATHING val ((3 << 1) rather then BIT(3)).

leds: Add driver for Qualcomm LPG

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.
