Add Nuvoton BMC NPCM750/730/715/705 Pulse Width Modulation (PWM) and Fan tacho driver. The Nuvoton BMC NPCM750/730/715/705 supports 8 PWM controller outputs and 16 Fan controller inputs. The driver provides a sysfs entries through which the user can configure the duty-cycle value from 0(off) and 255(full speed) and read the fan tacho rpm value.

Description:
|
|
------------
|
|
This driver implements support for NUVOTON NPCM7XX PWM and Fan Tacho
|
|
controller. The PWM controller supports up to 8 PWM outputs. The Fan tacho
|
|
controller supports up to 16 tachometer inputs.
|
|
|
|
The driver provides the following sensor accesses in sysfs:
|
|
|
|
fanX_input ro provide current fan rotation value in RPM as reported
|
|
by the fan to the device.
|
|
|
|
pwmX rw get or set PWM fan control value. This is an integer
|
|
value between 0(off) and 255(full speed).
