* hwmon: (pmbus/lm25066) Add support for TI LM5066IXo Wang2017-08-301-2/+7
| | | | | | | | | | The TI LM5066I hotswap controller is a more accurate version of the LM5066 device already supported. It has different measurement conversion coefficients than the LM5066, so it needs to be recognized as a different device.

* hwmon: (adt7475) fan stall preventionChris Packham2017-06-121-0/+5
| | | | | | | | | | | By default adt7475 will stop the fans (pwm duty cycle 0%) when the temperature drops past Tmin - hysteresis. Some systems want to keep the fans moving even when the temperature drops so add new sysfs attributes that configure the enhanced acoustics min 1-3 which allows the fans to run at the minimum configure pwm duty cycle.

| | | | | | | | | | | | | | | 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.
