^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) - #pwm-cells : 		Number of cells used to specify a PWM. First cell
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) 			specifies the per-chip index of the PWM to use and the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) 			second cell is the period in nanoseconds - fixed to 2
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) 			for STiH41x.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) - reg :			Physical base address and length of the controller's
