+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).
