Usage Notes ----------- This driver does not probe for PMBus devices. You will have to instantiate devices explicitly. Example: the following commands will load the driver for an TPS53681 at address 0x60 on I2C bus #1:: # modprobe tps53679 # echo tps53681 0x60 > /sys/bus/i2c/devices/i2c-1/new_device Sysfs attributes ---------------- ======================= ======================================================== in1_label "vin" in1_input Measured input voltage. in1_lcrit Critical minimum input voltage TPS53679, TPS53681, TPS53688 only. in1_lcrit_alarm Input voltage critical low alarm.
