| Kernel driver lineage-pem | ||
| ========================= | ||
|
|
||
| Supported devices: | ||
| * Lineage Compact Power Line Power Entry Modules | ||
| Prefix: 'lineage-pem' | ||
| Addresses scanned: - | ||
| Documentation: | ||
| http://www.lineagepower.com/oem/pdf/CPLI2C.pdf | ||
|
|
||
| Author: Guenter Roeck <guenter.roeck@ericsson.com> | ||
|
|
||
|
|
||
| Description | ||
| ----------- | ||
|
|
||
| This driver supports various Lineage Compact Power Line DC/DC and AC/DC | ||
| converters such as CP1800, CP2000AC, CP2000DC, CP2100DC, and others. | ||
|
|
||
| Lineage CPL power entry modules are nominally PMBus compliant. However, most | ||
| standard PMBus commands are not supported. Specifically, all hardware monitoring | ||
| and status reporting commands are non-standard. For this reason, a standard | ||
| PMBus driver can not be used. | ||
|
|
||
|
|
||
| Usage Notes | ||
| ----------- | ||
|
|
||
| This driver does not probe for Lineage CPL devices, since there is no register | ||
| which can be safely used to identify the chip. You will have to instantiate | ||
| the devices explicitly. | ||
|
|
||
| Example: the following will load the driver for a Lineage PEM at address 0x40 | ||
| on I2C bus #1: | ||
| $ modprobe lineage-pem | ||
| $ echo lineage-pem 0x40 > /sys/bus/i2c/devices/i2c-1/new_device | ||
|
|
||
| All Lineage CPL power entry modules have a built-in I2C bus master selector | ||
| (PCA9541). To ensure device access, this driver should only be used as client | ||
| driver to the pca9541 I2C master selector driver. | ||
|
|
||
|
|
||
| Sysfs entries | ||
| ------------- | ||
|
|
||
| All Lineage CPL devices report output voltage and device temperature as well as | ||
| alarms for output voltage, temperature, input voltage, input current, input power, | ||
| and fan status. | ||
|
|
||
| Input voltage, input current, input power, and fan speed measurement is only | ||
| supported on newer devices. The driver detects if those attributes are supported, | ||
| and only creates respective sysfs entries if they are. | ||
|
|
||
| in1_input Output voltage (mV) | ||
| in1_min_alarm Output undervoltage alarm | ||
| in1_max_alarm Output overvoltage alarm | ||
| in1_crit Output voltage critical alarm | ||
|
|
||
| in2_input Input voltage (mV, optional) | ||
| in2_alarm Input voltage alarm | ||
|
|
||
| curr1_input Input current (mA, optional) | ||
| curr1_alarm Input overcurrent alarm | ||
|
|
||
| power1_input Input power (uW, optional) | ||
| power1_alarm Input power alarm | ||
|
|
||
| fan1_input Fan 1 speed (rpm, optional) | ||
| fan2_input Fan 2 speed (rpm, optional) | ||
| fan3_input Fan 3 speed (rpm, optional) | ||

| Kernel driver ltc4151 | ||
| ===================== | ||
|
|
||
| Supported chips: | ||
| * Linear Technology LTC4151 | ||
| Prefix: 'ltc4151' | ||

|
|
||
| Description | ||
| ----------- | ||
|
|
||
| The LTC4151 is a High Voltage I2C Current and Voltage Monitor. | ||
|
|
||
|
|
||
| Usage Notes | ||
| ----------- | ||
|
|
||
| This driver does not probe for LTC4151 devices, since there is no register | ||
| which can be safely used to identify the chip. You will have to instantiate | ||
| the devices explicitly. | ||
|
|
||
| Example: the following will load the driver for an LTC4151 at address 0x6f | ||
| on I2C bus #0: | ||
| # modprobe ltc4151 | ||
| # echo ltc4151 0x6f > /sys/bus/i2c/devices/i2c-0/new_device | ||
|
|
||
|
|
||
| Sysfs entries | ||
| ------------- | ||
|
|
||
| Voltage readings provided by this driver are reported as obtained from the ADIN | ||
| and VIN registers. | ||
|
|
||
| Current reading provided by this driver is reported as obtained from the Current | ||
| Sense register. The reported value assumes that a 1 mOhm sense resistor is | ||
| installed. | ||
