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.Signed-off-by: Xo Wang

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.Signed-off-by: Chris Packham

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.Signed-off-by: Jaghathiswari Rankappagounder Natarajan

Inform the user that hwmon_device_register() is deprecated,
