Merge tag 'leds-next-6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/leds 

Pull LED updates from Lee Jones:

 - Allow struct bin_attribute instances to be placed in read-only memory
   for enhanced protection

 - Fix a memory leak in the cht-wcove driver by using
   devm_led_classdev_register()

 - Fix an OF node reference leak in the netxbig driver

 - Ensure PWM is disabled properly in pwm-multicolor suspend

 - Add support for Texas Instruments LP8864, LP8864S, LP8866
   LED-backlight drivers

 - Add support for STMicroelectronics's LED1202 12-channel LED driver

 - Convert LP8860 bindings to YAML format

 - Add bindings for the TI LP8864/LP8866 LED drivers

 - Add LED1202 LED controller bindings

 - Fix path to color definitions in leds-class-multicolor.yaml

 - Add pm660l compatible to qcom,spmi-flash-led bindings

 - Extend cznic,turris-omnia-leds binding with interrupts property

 - Add documentation for the STMicroelectronics LED1202 driver

 - Add entry for AAEON UP board FPGA drivers in MAINTAINERS

 - Fix a wrong format specifier in the ledtrig-activity driver

 - Fix a bug in the lp8860 driver where only half of the EEPROM was
   written

* Texas Instruments - lp8860 4-Channel LED Driver



The LP8860-Q1 is an high-efficiency LED

driver with boost controller. It has 4 high-precision

current sinks that can be controlled by a PWM input

signal, a SPI/I2C master, or both.



Required properties:

	- compatible :

		"ti,lp8860"

	- reg : I2C slave address

	- #address-cells : 1

	- #size-cells : 0



Optional properties:

	- enable-gpios : gpio pin to enable (active high)/disable the device.

	- vled-supply : LED supply



Required child properties:

	- reg : 0



Optional child properties:

	- function : see Documentation/devicetree/bindings/leds/common.txt

	- color : see Documentation/devicetree/bindings/leds/common.txt

	- label : see Documentation/devicetree/bindings/leds/common.txt (deprecated)

	- linux,default-trigger :

	   see Documentation/devicetree/bindings/leds/common.txt



Example:



#include <dt-bindings/leds/common.h>



led-controller@2d {

	compatible = "ti,lp8860";

	#address-cells = <1>;

	#size-cells = <0>;

	reg = <0x2d>;

	enable-gpios = <&gpio1 28 GPIO_ACTIVE_HIGH>;

	vled-supply = <&vbatt>;



	led@0 {

		reg = <0>;

		function = LED_FUNCTION_BACKLIGHT;

		color = <LED_COLOR_ID_WHITE>;

		linux,default-trigger = "backlight";

	};

}
