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 .../hwmon/aspeed,ast2600-pwm-tachometer.yaml | 137 ++++ .../hwmon/aspeed2600-pwm-tachometer.rst | 27 + Documentation/hwmon/index.rst | 1 + arch/arm/boot/dts/aspeed-ast2600-evb.dts | 152 ++++ arch/arm/boot/dts/aspeed-g6.dtsi | 10 + drivers/hwmon/Kconfig | 10 + drivers/hwmon/Makefile | 1 + drivers/hwmon/aspeed2600-pwm-tacho.c | 756 ++++++++++++++++++ 8 files changed, 1094 insertions(+) create mode 100644 Documentation/devicetree/bindings/hwmon/aspeed,ast2600-pwm-tachometer.yaml create mode 100644 Documentation/hwmon/aspeed2600-pwm-tachometer.rst create mode 100644 drivers/hwmon/aspeed2600-pwm-tacho.c -- 2.25.1
