.SH "NAME"

|
|
asem \- driver for UPS in ASEM PB1300
|
||
|
|
.SH "NOTE"
|
||
|
|
.sp
|
||
|
|
This man page only documents the hardware\-specific features of the \fBasem\fR driver\&. For information about the core driver, see \fBnutupsdrv\fR(8)\&.
|
||
|
|
.SH "SUPPORTED HARDWARE"
|
||
|
|
.sp
|
||
|
|
The \fBasem\fR 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\&.
|
||
|
|
.sp
|
||
|
|
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\&.
|
||
|
|
.SH "EXTRA ARGUMENTS"
|
||
|
|
.sp
|
||
|
|
The required parameter for this driver is the I2C bus name:
|
||
|
|
.PP
|
||
|
|
\fBport\fR=\fIdev\-node\fR
|
||
|
|
.RS 4
|
||
|
|
On the Asem PB1300, this should be
|
||
|
|
/dev/i2c\-7
|
||
|
|
for the i801 SMBUS adapter\&.
|
||
|
|
.RE
|
||
|
|
.sp
|
||
|
|
This driver also supports the following optional settings:
|
||
|
|
.PP
|
||
|
|
\fBlb\fR=\fInum\fR
|
||
|
|
.RS 4
|
||
|
|
Set the low battery threshold to
|
||
|
|
\fInum\fR
|
||
|
|
volts\&.
|
||
|
|
.RE
|
||
|
|
.PP
|
||
|
|
\fBhb\fR=\fInum\fR
|
||
|
|
.RS 4
|
||
|
|
Set the high battery threshold to
|
||
|
|
\fInum\fR
|
||
|
|
volts\&.
|
||
|
|
.RE
|
||
|
|
.SH "INSTALLATION"
|
||
|
|
.sp
|
||
|
|
This driver is specific to the Linux I2C API, and requires the lm_sensors libi2c\-dev or its equivalent to compile\&.
|
||
|
|
.sp
|
||
|
|
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\(cqll need to relax the ACPI resources check\&. For example, you can boot with the acpi_enforce_resources=lax option\&.
|
||
|
|
.SH "KNOWN ISSUES AND BUGS"
|
||
|
|
.sp
|
||
|
|
The driver shutdown function is not implemented, so other arrangements must be made to turn off the UPS\&.
