// SSDT-BATC.dsl
//
// Based on https://github.com/RehabMan/OS-X-ACPI-Battery-Driver/blob/master/SSDT-BATC.dsl
//
// An SSDT to combine two batteries into one
// initial work/testing by ag6952563 (with assistance by RehabMan)
// finalize into generic SSDT by RehabMan
// some code cleanup/optimization/and bug fixing by RehabMan
// modifications to work VirtualSMC SMCBatteryManager by armenio
// add _BIX (easy, following the original code from RehabMan) by armenio
//
// OS X support for multiple batteries is a bit buggy.
// This SSDT can be used to combine two batteries into one,
// avoiding the bugs.
//
// It may need modification depending on the ACPI path of your
// existing battery objects.
//
// IMPORTANT:
//
// To use this SSDT, you must also patch any Notify for either BAT0 or BAT1
// objects.
//
// The Notify is used to tell the system when a battery is removed or added.
//
// Any code:
// Notify (...BAT0, ...)
// -or
// Notify (...BAT1, ...)
//
// Must be changed to:
// Notify (...BATC, ...)
//
// Refer to Dual Battery Support.md for patching details
