-Module Parameters
------------------
-
-* vref: int
- Default: 1250 (mV)
- Reference voltage on VREF_ADC pin in mV. It should not be necessary to set
- this parameter unless a non-default reference voltage is used.
-
-
-Description
------------
-
-[From datasheet] The SMM665 is an Active DC Output power supply Controller
-that monitors, margins and cascade sequences power. The part monitors six
-power supply channels as well as VDD, 12V input, two general-purpose analog
-inputs and an internal temperature sensor using a 10-bit ADC.
-
-Each monitored channel has its own high and low limits, plus a critical
-limit.
-
-Support for SMM465, SMM764, and SMM766 has been implemented but is untested.
-
-
-Usage Notes
------------
-
-This driver does not probe for devices, since there is no register which
-can be safely used to identify the chip. You will have to instantiate
-the devices explicitly. When instantiating the device, you have to specify
-its configuration register address.
-
-Example: the following will load the driver for an SMM665 at address 0x57
-on I2C bus #1:
-$ modprobe smm665
-$ echo smm665 0x57 > /sys/bus/i2c/devices/i2c-1/new_device
-
-
-Sysfs entries
--------------
-
-This driver uses the values in the datasheet to convert ADC register values
-into the values specified in the sysfs-interface document. All attributes are
-read only.
-
-Min, max, lcrit, and crit values are used by the chip to trigger external signals
-and/or other activity. Triggered signals can include HEALTHY, RST, Power Off,
-or Fault depending on the chip configuration. The driver reports values as lcrit
-or crit if exceeding the limits triggers RST, Power Off, or Fault, and as min or
-max otherwise. For details please see the SMM665 datasheet.
-
-For SMM465 and SMM764, values for Channel E and F are reported but undefined.
