Kernel driver lineage-pem

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.

Description
|
||||
-----------
|
||||
|
||||
This driver supports hardware montoring 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.

Sysfs entries

-------------

supported, and determines available sensors from this information.
|
||||
Attribute files only exist if respective sensors are suported by the chip.
|
||||
Labels are provided to inform the user about the sensor associated with
|
||||
a given sysfs entry.

||||
|

|
||||
attributes are read-only.

This driver implements support for the Winbond W83627EHF, W83627EHG,

The chips implement three temperature sensors, five fan rotation

VID (6 pins for the 627EHF/EHG, 8 pins for the 627DHG and 667HG), alarms

The temperature sensor sources on W82677HG-B, NCT6775F, and NCT6776F are
