^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) ------------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) This driver implements support for NUVOTON NPCM7XX PWM and Fan Tacho
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) controller. The PWM controller supports up to 8 PWM outputs. The Fan tacho
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) controller supports up to 16 tachometer inputs.
