Subject: [Resend Patch 0/9] I2C ACPI operation region handler support 

ACPI 5.0 spec(5.5.2.4.5) defines GenericSerialBus(i2c, spi, uart) operation
region. It allows ACPI aml code able to access such kind of devices to
implement some ACPI standard method.

On the Asus T100TA, Bios use GenericSerialBus operation region to access
i2c device to get battery info. So battery function depends on the I2C
operation region support. Here is the bug link.
