/* =================== Generic PnP Device =================== */
/*
* Generic setup for PnP devices.
*
* Controlled by the following preprocessor defines:
*
* SUPERIO_CHIP_NAME The name of the Super I/O chip (unique, required)
* SUPERIO_PNP_HID The EisaId string that identifies this device (optional)
* SUPERIO_PNP_LDN The logical device number on the Super I/O
* chip for this device (required)
* SUPERIO_PNP_DDN A string literal that identifies the dos device
* name (DDN) of this device (e.g. "COM1", optional)
* SUPERIO_PNP_PM_REG Identifier of a 1-bit register to power down
* the logical device (optional)
* SUPERIO_PNP_PM_VAL The value for SUPERIO_PNP_PM_REG to power the logical
* device down (required if SUPERIO_PNP_PM_REG is defined)
* SUPERIO_PNP_PM_LDN The logical device number to access the PM_REG
* bit (required if SUPERIO_PNP_PM_REG is defined)
* SUPERIO_PNP_IO0 The alignment and length of the first PnP i/o
* resource (comma separated, e.g. `0x02, 0x08`,
* optional)
* SUPERIO_PNP_IO1 The alignment and length of the second PnP i/o
* resource (comma separated, e.g. `0x02, 0x08`,
* optional)
* SUPERIO_PNP_IO2 The alignment and length of the third PnP i/o
* resource (comma separated, e.g. `0x02, 0x08`,
* optional)
* SUPERIO_PNP_IRQ0 If defined, the first PnP IRQ register is enabled
* SUPERIO_PNP_IRQ1 If defined, the second PnP IRQ register is enabled
* SUPERIO_PNP_DMA If defined, the PnP DMA register is enabled
