Aspeed AST2600 is a server management SoC which has 16 PWM channels and
16 fan tacho channel.

This series of patch provides AST2600 PWM/Fan tacho support in hwmon
class.

The driver provides a sysfs interface, and user can configure PWM duty
cycle and read current FAN speed in RPM.

Change since v1:
- dt-binding rewrote with dt schema format
- register hwmon driver with devm_hwmon_device_register_with_info()
- moving default configurations to device tree

*** BLURB HERE ***

Troy Lee (4):
dt-bindings: hwmon: Add Aspeed AST2600 PWM/Fan
hwmon: Add Aspeed AST2600 support
ARM: dts: aspeed: Add Aspeed AST2600 PWM/Fan node in devicetree
hwmon: Support Aspeed AST2600 PWM/Fan tachometer
