This man page only documents the hardware-specific features of the
|
|
|
|
|
*asem* driver. For information about the core driver, see

SUPPORTED HARDWARE

|
|
The *asem* driver supports the UPS in ASEM PB1300 embedded PCs. Likely other
|
|
|
|
|
I2C devices from the same manufacturer will work too, since this is a "custom"
|
|
|
|
|
charger.
|
|
|
|
|
|
|
|
|
|
Seems that there are two versions of the charger. Older one is based on
|
|
|
|
|
Max1667, newer one is a custom solution. Both are on I2C address 0x09.
|
|
|
|
|
To be compatible with both versions, the driver just reads bit 15 of address
|
|
|
|
|
0x13 which yields online/on battery status.
|
|
|
|
|
Battery monitor is a BQ2060 at address 0x0B.

EXTRA ARGUMENTS
|
|
|
|
|
---------------
|
|
|
|
|
|
|
|
|
|
The required parameter for this driver is the I2C bus name:
|
|
|
|
|
|
|
|
|
|
*port*='dev-node'::
|
|
|
|
|
On the Asem PB1300, this should be `/dev/i2c-7` for the i801 SMBUS adapter.
|
|
|
|
|
|
|
|
|
|
This driver also supports the following optional settings:
|
|
|
|
|
|
|
|
|
|
*lb*='num'::
|
|
|
|
|
Set the low battery threshold to 'num' volts.

|
|
|
*hb*='num'::
|
|
|
|
|
Set the high battery threshold to 'num' volts.
|
|
|
|
|
|
|
|
|
|
INSTALLATION

|
|
|
This driver is specific to the Linux I2C API, and requires the lm_sensors
|
|
|
|
|
libi2c-dev or its equivalent to compile.
|
|
|
|
|
|
|
|
|
|
Beware that the SystemIO memory used by the I2C controller is reserved by ACPI.
|
|
|
|
|
If only a native I2C driver (e.g. i2c_i801, as of 3.5.X Linux kernels) is
|
|
|
|
|
available, then you'll need to relax the ACPI resources check. For example, you
|
|
|
|
|
can boot with the `acpi_enforce_resources=lax` option.

|
|
|
The driver shutdown function is not implemented, so other arrangements must be
|
|
|
|
|
made to turn off the UPS.
