3.5.2.6 SerialIo Configuration
I2C2 Controller

Enable/Disable SerialIo Controller.
If a given device's Function 0 PSF disabling is skipped, the PSF default will remain
and device PCI CFG Space will still be visible. This is needed to allow PCI enu-
merator 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)
I2C4 Controller

Enable/Disable SerialIo Controller. For I2C5 and UART2 to work, this device has
to be enabled.
SPIO Controller

Enable/Disable SerialIo Controller.
If a given device's Function 0 PSF disabling is skipped, the PSF default will remain
and device PCI CFG Space will still be visible. This is needed to allow PCI enu-
merator 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

1. Child device is enabled like CNVi Bluetooth (\_SB.PC00.UA00.BTH0)
