Subject: [PATCH 0/4] hwmon: aspeed2600-pwm-tacho: Add driver support

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.

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