/*
 * include this file into a mainboard's DSDT _SB device tree and it will expose the
 * W83627HF SuperIO and its functionality.
 *
 * Devices are marked as nonexistant if they got 0x00000000 as I/O base address
 * (compatibility with legacy bios, which disables logical devices that way)
 *
 * It allows the change of IO ports, IRQs and DMA settings on most logical
 * devices, disabling and reenabling logical devices and controlling power
 * saving mode on logical devices or the whole chip.
 *
 * Notes:
 * - ECP mode of parallel port not implemented, DMA settings of parallel port
 *   will be reset on DSDT init
 * - Hardware monitor is only shown as "Motherboard Resource", shows no real
 *   functionality
 *
 * Controllable through preprocessor macros:
 * NO_W83627HF_FDC:      don't expose the floppy disk controller
 * NO_W83627HF_FDC_ENUM: don't try to enumerate the connected floppy drives
 * NO_W83627HF_PPORT:    don't expose the parallel port
 * NO_W83627HF_UARTA:    don't expose the first serial port
 * NO_W83627HF_UARTB:    don't expose the second serial port (already hidden
 *                       if UARTB is configured as IRDA port by firmware)
 * NO_W83627HF_IRDA:     don't expose the IRDA port (already hidden if UARTB is
 *                       configured as serial port by firmware)
 * NO_W83627HF_CIR:      don't expose the Consumer Infrared functionality
 * NO_W83627HF_KBC:      don't expose the keyboard controller
 * NO_W83627HF_PS2M:     don't expose the PS/2 mouse functionality of the
 *                       keyboard controller
 * NO_W83627HF_GAME:     don't expose the game port
 * NO_W83627HF_MIDI:     don't expose the MIDI port
 * NO_W83627HF_HWMON:    don't expose the hardware monitor as
 *                       PnP "Motherboard Ressource"
 * W83627HF_KBC_COMPAT:  show the keyboard controller and the PS/2 mouse as
 *                       enabled if it is disabled but an address is assigned
 *                       to it. This may be neccessary in some cases.
