Bluetooth: btintel: Set Per Platform Antenna Gain(PPAG)
Antenna gain is defined as the antenna’s ability to
increase the Tx power in a given direction. Intel
is certifying its products with fixed reference
antenna peak gain values (3/5dBi). The feature takes
into account the actual antenna gain, and increases
output power values, which results in a performance
improvement.
After firmware download is completed, driver reads from
ACPI table and configures PPAG as required. ACPI table
entry for PPAG is defined as below.
Name (PPAG, Package (0x02)
{
0x00000001,
Package (0x02)
{
0x00000012, /* Bluetooth Domain */
0x00000001 /* 1 - Enable PPAG, 0 - Disable PPAG */
}
})
