* Controlled by the following preprocessor defines:

|
*
|
|
* SUPERIO_CHIP_NAME The name of the Super I/O chip (unique, required)
|
|
* SUPERIO_UART_LDN The logical device number on the Super I/O
|
|
* chip for this UART (required)
|
|
* SUPERIO_UART_DDN A string literal that identifies the dos device
|
|
* name (DDN) of this uart (e.g. "COM1", optional)
|
|
* SUPERIO_UART_PM_REG Identifier of a 1-bit register to power down
|
|
* the UART (optional)
|
|
* SUPERIO_UART_PM_VAL The value for SUPERIO_UART_PM_REG to power the logical
|
|
* device down (required if SUPERIO_UART_PM_REG is defined)
|
|
* SUPERIO_UART_PM_LDN The logical device number to access the PM_REG
|
|
* bit (required if SUPERIO_UART_PM_REG is defined)
