drivers: hwmon: Support for ASPEED PWM/Fan tach
The ASPEED AST2400/2500 PWM controller supports 8 PWM output ports. The ASPEED AST2400/2500 Fan tach controller supports 16 tachometer inputs. The device driver matches on the device tree node. The configuration values are read from the device tree and written to the respective registers. The driver provides a sysfs entries through which the user can configure the duty-cycle value (ranging from 0 to 100 percent) and read the fan tach rpm value.
