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.
