The LM3697 is a single function LED driver. The single function LED
driver needs to reside in the LED directory as a dedicated LED driver
and not as a MFD device. The device does have common brightness and ramp
features and those can be accomodated by a TI LMU framework.
The LM3697 dt binding needs to be moved from the ti-lmu.txt and a dedicated
LED dt binding needs to be added. The new LM3697 LED dt binding will then
reside in the Documentation/devicetree/bindings/leds directory and follow the

Add the lm3532 device tree documentation.
Remove lm3532 device tree reference from the ti_lmu devicetree
documentation.
With the addition of the dedicated lm3532 documentation the device
can be removed from the ti_lmu.txt.
The reason for this is that the lm3532 dt documentation now defines
the ability to control LED output strings against different control
banks or groups multiple strings to be controlled by a single control
bank.
Another addition was for ALS lighting control and configuration. The
LM3532 has a feature that can take in the ALS reading from 2 separate
ALS devices and adjust the brightness on the strings that are configured
to support this feature.
Finally the device specific properties were moved to the parent node
as these properties are not control bank configurable. These include
the runtime ramp and the ALS configuration.

Use integers (reg property) to tell the number of the LED to the driver
instead of the node name. While both of these approaches are currently
used by the LED bindings, using integers will require less driver changes
for ACPI support. Additionally, it will make possible LED naming using
chip and LED node names, effectively making the label property most useful
for human-readable names only.

On Baseboard Management Controller (BMC) systems it's sometimes
necessary for a LED to retain its state across a BMC reset (which is
independent of the host system state). Add a devicetree property to
describe this behaviour. The property would typically be used in
conjunction with 'default-state = "keep"'.

"This time we're removing more than adding:
Removed drivers:
leds-versatile:
- all users of the Versatile LED driver are deleted and replaced
with the very generic leds-syscon
leds-sead3:
- SEAD3 is using the generic leds-syscon & regmap based
register-bit-led driver
LED class drivers improvements:
ledtrig-gpio:
- use threaded IRQ, which both simplifies the code because we can
drop the workqueue indirection, and it enables using the trigger
for GPIOs that work with threaded IRQs themselves
- refresh LED state after GPIO change since the new GPIO may have
a different state than the old one
leds-lp55xx:
- make various arrays static const
leds-pca963x:
- add bindings to invert polarity"

Some LEDs can be related to a specific device(s) described in the DT.
This property allows specifying such relations. E.g. USB LED should
usually be used to indicate some USB port(s) state.
Please note this binding is designed to be generic and not influenced by
any operating system design. Linux developers may find "trigger" part a
bit confusing since in Linux triggers are separated drivers. It
shouldn't define the binding though (we shouldn't add an extra level of
indirection).
