Merge tag 'leds-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/pavel/linux-leds 

Pull LED updates from Pavel Machek:
 "Quite a lot of stuff is going on here. Great cleanups/fixes from Marek
  and others are biggest part.

  I limited CPU LED trigger to 8 LEDs, because it was willing to
  register 1024 'triggers' on machine with 1024 CPUs. I don't believe it
  will cause any problems, but we can raise the limit if it does"

title: LED driver for LP50XX RGB LED from Texas Instruments.



maintainers:

  - Dan Murphy <dmurphy@ti.com>



description: |

  The LP50XX is multi-channel, I2C RGB LED Drivers that can group RGB LEDs into

  a LED group or control them individually.



  The difference in these RGB LED drivers is the number of supported RGB

  modules.

LEDs connected to tca6507



Required properties:

- compatible : should be : "ti,tca6507".

- #address-cells: must be 1

- #size-cells: must be 0

- reg: typically 0x45.



Optional properties:

- gpio-controller: allows lines to be used as output-only GPIOs.

- #gpio-cells: if present, must not be 0.



Each led is represented as a sub-node of the ti,tca6507 device.



LED sub-node properties:

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

- reg : number of LED line (could be from 0 to 6)

- linux,default-trigger : (optional)

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

- compatible: either "led" (the default) or "gpio".



Examples:



tca6507@45 {

	#size-cells = <0>;

	reg = <0x45>;
