^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  1) Device Tree Bindings for Register Bit LEDs
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  2) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  3) Register bit leds are used with syscon multifunctional devices
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4) where single bits in a certain register can turn on/off a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) single LED. The register bit LEDs appear as children to the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) syscon device, with the proper compatible string. For the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) syscon bindings see:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) Documentation/devicetree/bindings/mfd/syscon.yaml

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) Each LED is represented as a sub-node of the syscon device. Each
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) node's name represents the name of the corresponding LED.
