> Add PWM fan controller driver for StarFive JHB100 SoC.
>
> Fan speed is controlled through up to 8 PWM channels supplied by an
> external PWM controller and exposed as pwm[1-8], and one PWM channel can
> drive up to two fans. The tachometer block supports 16 independent
> inputs and reports fan speed in RPM through the hwmon sysfs interface,
> along with stall and low-speed alarms.

> For this controller, the special clock and reset operation sequence is:
> probe: clk_prepare_enable() then reset_control_deassert()
> remove: clk_disable_unprepare() then reset_control_assert()
