^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  1) Marvell PWM controller
^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 one or more of:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5)   - "marvell,pxa250-pwm"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6)   - "marvell,pxa270-pwm"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7)   - "marvell,pxa168-pwm"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8)   - "marvell,pxa910-pwm"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) - reg: Physical base address and length of the registers used by the PWM channel
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10)   Note that one device instance must be created for each PWM that is used, so the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11)   length covers only the register window for one PWM output, not that of the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12)   entire PWM controller.  Currently length is 0x10 for all supported devices.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) - #pwm-cells: Should be 1.  This cell is used to specify the period in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14)   nanoseconds.
