asem - Driver for UPS in ASEM PB1300

       Giuseppe Corbelli <giuseppe.corbelli@copanitalia.com>

       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.

       This driver is specific to the Linux I2C API, and requires the libi2c-dev library and headers from
       lm_sensors project, 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.

       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 bit15
       of address 0x13 which yields online/on battery status.

       Battery monitor is a BQ2060 at address 0x0B.
