Add support for grouping individual PCA963x channels into a multicolor
LED by introducing a multi-led@N node pattern. This follows the
convention established by other multicolor LED drivers such as
kinetic,ktd202x.
This is necessary to support and model hardware setups where multiple
PWM channels drive a single physical RGB LED.

The pca9635 supports 16 LED channels, unlike the pca9634 which only
supports 8. The allOf conditional grouped both chips under a single
else branch capping reg at a maximum of 7.
Give pca9634 its own if/then block and set maximum: 15 unconditionally
in the top-level led@ node, making it the default for pca9635 and any
future compatible. Also tighten the node name regex from [0-9a-f]+ to
[0-9a-f] to match the single-digit hardware limit.

Convert the Texas Instruments TPS65217 bindings to DT schema.
During the conversion, the following updates were made:
- Documented the 'regulators', 'charger' and 'pwrbutton' child nodes,
which are used by the boards but were missing from the old txt
binding.
- Documented the 'interrupts', 'interrupt-controller', '#interrupt-cells'
and 'ti,pmic-shutdown-controller' properties, which are used by the
am335x boards and read by the driver.
The regulator/tps65217.txt binding documented the same 'ti,tps65217'
compatible and is superseded by this schema, so remove it as well.

referenced by the trigger-sources property. This is already documented
in the trigger-sources property description and is used in at least one

There is no use of double colon '::' in YAML. OTOH, the literal style
block, e.g. using '|' treats all characters as content [1] therefore
single use of ':' in descriptions is perfectly fine, whenever '|' is
used.
Cleanup existing code, so the confusing style won't be re-used in new
contributions.

Pull LED updates from Lee Jones:
"New Support & Features:
- Add support for the TI LP5812 4x3 matrix RGB LED driver, including
autonomous animation engine control and extensive scan multiplexing
modes
- Add a new driver for the ams Osram AS3668 4-channel I2C LED
controller
- Extend the is31fl32xx driver to support the is31fl3293 variant,
which features 3 channels and 12-bit PWM resolution
Improvements & Fixes:
- Prevent the ExpressWire KTD2801 chip from entering an undefined
state by disabling interrupts during time-sensitive communication
- Ensure the Qualcomm LPG driver detects hardware write failures by
checking the return value of regmap_bulk_write() during LUT
programming
- Fix kernel-doc warnings in the lm3692x driver by documenting
missing struct members and standardizing the comment style
- Update the ExpressWire library to use fsleep() and unexport
internal-only functions
- Improve the is31fl32xx driver by reordering code to eliminate
unnecessary forward declarations
Cleanups & Refactoring:
- Simplify the LP55XX common LED driver by utilizing the
for_each_available_child_of_node_scoped() macro for more concise
node iteration
Device Tree Bindings Updates:
- Add new YAML bindings for the TI LP5860 and LP5812 LED controllers,
and the ams Osram AS3668
- Convert the TI LM3697 white LED driver binding to DT schema format
- Allow multicolor LED nodes to be named with numeric suffixes (e.g.,
multi-led-0) to handle multiple instances without unit addresses
- Document support for the PMH0101 variant in the Qualcomm LPG PWM
and SPMI Flash LED bindings
- Add the issi,is31fl3293 compatible string to the is31fl32xx
binding"

In some cases, for example when using multiple instances of
leds-group-multicolor, a board may have multiple multi-leds which can't
be distinguished by unit address. In such cases it should be possible to
name them differently, for example multi-led-0 and multi-led-1. This
patch adds another node name pattern to leds-class-multicolor.yaml to
allow such names.
