hwmon: add Axiado AX3000 and AX3005 PWM fan controller driver
Add support for the PWM fan controller found on the Axiado AX3000 and
AX3005 SoCs.
The controller uses a hardware tachometer block and interrupt to measure
fan speed. Fan speed is controlled through a PWM signal supplied by an
external PWM controller.
Register the controller with the hwmon subsystem and expose the standard
fan1_input and pwm1 attributes. The physical fan is represented by a fan
child node containing the PWM specifier and the optional
pulses-per-revolution property. If pulses-per-revolution is not specified,
the driver uses two pulses per revolution.
The driver was tested on AX3000 and AX3005 boards.
