^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  1) LED connected to PWM
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  2) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  3) Required properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4) - compatible : should be "pwm-leds".
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) Each LED is represented as a sub-node of the pwm-leds device.  Each
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) node's name represents the name of the corresponding LED.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) LED sub-node properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) - pwms : PWM property to point to the PWM device (phandle)/port (id) and to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11)   specify the period time to be used: <&phandle id period_ns>;
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) - pwm-names : (optional) Name to be used by the PWM subsystem for the PWM device
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13)   For the pwms and pwm-names property please refer to:
