Add PSU PWM sensor to support FSC Add PSU PWM sensor to allow FSC control PSU fan pwm. Tested: Change property Target to 100 in dbus interface xyz.openbmc_project.Control.FanPwm path /xyz/openbmc_project/control/fanpwm/Pwm_PSU1_Fan_1, the value in /sys/class/hwmon/hwmonx/fan1_target also become 100, and value property in interface /xyz/openbmc_project/sensors/fan_pwm/Pwm_PSU1_Fan_1 become 39.2157 Run ipmitool sensor list, bellow sensors will show like: Pwm PSU1 Fan 1 | 39.200 | unspecified | ok | na | na | na | na | na | na Pwm PSU2 Fan 1 | 0.000 | unspecified | ok | na | na | na | na | na | na Signed-off-by: Cheng C Yang <cheng.c.yang@linux.intel.com> Change-Id: I6a4d50912a190297dbcf4a4e5c511607f71cb0c0
dbus-sensors is a collection of sensor applications that provide the xyz.openbmc_project.Sensor collection of interfaces. They read sensor values from hwmon, d-bus, or direct driver access to provide readings. Some advance non-sensor features such as fan presence, pwm control, and automatic cpu detection (x86) are also supported.
runtime re-configurable from d-bus (entity-manager or the like)
isolated: each sensor type is isolated into its own daemon, so a bug in one sensor is unlikely to affect another, and single sensor modifications are possible
async single-threaded: uses sdbusplus/asio bindings
multiple data inputs: hwmon, d-bus, direct driver access
