From: Troy Lee
Date: Wed Dec 09 2020 - 03:02:39 EST
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
