Description
-----------
This driver supports hardware monitoring for various PMBus compliant devices.
It supports voltage, current, power, and temperature sensors as supported
by the device.
Each monitored channel has its own high and low limits, plus a critical
limit.
Fan support will be added in a later version of this driver.
Usage Notes
-----------
This driver does not probe for PMBus devices, since there is no register
which can be safely used to identify the chip (The MFG_ID register is not
supported by all chips), and since there is no well defined address range for
PMBus devices. You will have to instantiate the devices explicitly.
Example: the following will load the driver for an LTC2978 at address 0x60
on I2C bus #1::
$ modprobe pmbus
$ echo ltc2978 0x60 > /sys/bus/i2c/devices/i2c-1/new_device
Platform data support
---------------------
Support for additional PMBus chips can be added by defining chip parameters in
a new chip specific driver file. For example, (untested) code to add support for
Emerson DS1200 power modules might look as follows::
static struct pmbus_driver_info ds1200_info = {
.pages = 1,
/* Note: All other sensors are in linear mode */
.direct[PSC_VOLTAGE_OUT] = true,
.direct[PSC_TEMPERATURE] = true,
.direct[PSC_CURRENT_OUT] = true,
.m[PSC_VOLTAGE_IN] = 1,
.b[PSC_VOLTAGE_IN] = 0,
.R[PSC_VOLTAGE_IN] = 3,
.m[PSC_VOLTAGE_OUT] = 1,
.b[PSC_VOLTAGE_OUT] = 0,
.R[PSC_VOLTAGE_OUT] = 3,
.m[PSC_TEMPERATURE] = 1,
.b[PSC_TEMPERATURE] = 0,
.R[PSC_TEMPERATURE] = 3,
.func[0] = PMBUS_HAVE_VIN | PMBUS_HAVE_IIN | PMBUS_HAVE_STATUS_INPUT
| PMBUS_HAVE_VOUT | PMBUS_HAVE_STATUS_VOUT
| PMBUS_HAVE_IOUT | PMBUS_HAVE_STATUS_IOUT
| PMBUS_HAVE_PIN | PMBUS_HAVE_POUT
| PMBUS_HAVE_TEMP | PMBUS_HAVE_STATUS_TEMP
| PMBUS_HAVE_FAN12 | PMBUS_HAVE_STATUS_FAN12,
};
static int ds1200_probe(struct i2c_client *client)
{
return pmbus_do_probe(client, &ds1200_info);
}
static const struct i2c_device_id ds1200_id[] = {
{"ds1200", 0},
{}
};
MODULE_DEVICE_TABLE(i2c, ds1200_id);
/* This is the driver that will be inserted */
static struct i2c_driver ds1200_driver = {
.driver = {
.name = "ds1200",
},
.probe_new = ds1200_probe,
.id_table = ds1200_id,
};
static int __init ds1200_init(void)
{
return i2c_add_driver(&ds1200_driver);
}
static void __exit ds1200_exit(void)
{
i2c_del_driver(&ds1200_driver);
}
Sysfs entries
-------------
When probing the chip, the driver identifies which PMBus registers are
supported, and determines available sensors from this information.
Attribute files only exist if respective sensors are supported by the chip.
Labels are provided to inform the user about the sensor associated with
a given sysfs entry.
The following attributes are supported. Limits are read-write; all other
attributes are read-only.
