SerialIo Configuration
I2C2 Controller
Enables/Disables SerialIo Controller
If given device is Function 0 PSF disabling is skipped. PSF default will remain and
device PCI CFG Space will still be visible. This is needed to allow PCI enumerator
access functions above 0 in a multifunction device.
The following devices depend on each other:
I2C0 and I2C1,2,3
UART0 and UART1,SPI0,1
UART2 and I2C4,5
UART 0 (00:30:00) cannot be disabled when:
1. Child device is enabled like CNVi Bluetooth (\_SB.PC00.UA00.BTH0)
UART 0 (00:30:00) cannot be enabled when:
1. I2S Audio codec is enabled (\_SB.PC00.I2C0.HDAC)
