+ * Include this file into a mainboard's DSDT _SB device tree and it will

+ *
+ * LDN State
+ * 0x1 UARTA Implemented, partially tested

+ * 0x4 HWM Not implemented
+ * 0x5 KBC Not implemented
+ * 0x6 GPIO6 Not implemented
+ * 0x7 WDT0&PLED Not implemented
+ * 0xa ACPI/PME/ERP Partially implemented
+ *
+ * Controllable through preprocessor defines:
+ * SUPERIO_DEV Device identifier for this SIO (e.g. SIO0)
+ * SUPERIO_PNP_BASE I/o address of the first PnP configuration register
+ * F81803A_SHOW_UARTA If defined, UARTA will be exposed.
+ * F81803A_SHOW_UARTB If defined, UARTB will be exposed.
+ * F81803A_SHOW_HWMON If defined, the hardware monitor will be exposed.
+ * F81803A_SHOW_PME If defined, the PME/EARP/ACPI will be exposed.
+ *
+ * Known issue:
+ * Do not enable UARTA and UARTB simultaneously, Linux boot will crash.
+ * Select one or the other.
