It looks like there is an I2C operation region that the AML code uses to
handle the battery specific things:
Scope (_SB.I2C1)
{
Name (UMPC, ResourceTemplate ()
{
I2cSerialBus (0x0048, ControllerInitiated, 0x000186A0,
AddressingMode7Bit, "\\_SB.I2C1",
0x00, ResourceConsumer, ,
)
})
Name (AVBL, Zero)
Method (_REG, 2, NotSerialized) // _REG: Region Availability
{
If (LEqual (Arg0, 0x09))
{
Store (Arg1, AVBL)
}
}
OperationRegion (DVUM, GenericSerialBus, Zero, 0x0100)
...
Unfortunately this is not supported in Linux yet.
