/* =================== 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_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 seperated, e.g. `0x02, 0x08`,
 *			optional)
 * SUPERIO_PNP_IO1	The alignment and length of the second PnP i/o
 *			resource (comma seperated, 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
