- 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.
