Overview
The superio set of functions are used for managing Super I/O devices. The functions provide support for raw configuration access, locating devices, device information, and device configuration.
The controller interface
The superio_vendor() function is used to get a vendor of the Super I/O controller dev. Possible return values are SUPERIO_VENDOR_ITE and SUPERIO_VENDOR_NUVOTON.
The superio_devid() function is used to get a device ID of the Super I/O controller dev.
The superio_revid() function is used to get a revision ID of the Super I/O controller dev.
The superio_find_dev() function is used to find a device on the superio(4) bus, specified by dev, that has the requested type and logical device number. Either of those, but not both, can be a wildcard. Supported types are SUPERIO_DEV_GPIO, SUPERIO_DEV_HWM, and SUPERIO_DEV_WDT. The wildcard value for type is SUPERIO_DEV_NONE. The wildcard value for ldn is -1.
The device interface
The superio_read() function is used to read data from the Super I/O configuration register of the device dev.
The superio_write() function is used to write data to the Super I/O configuration register of the device dev.
The superio_dev_enable(), superio_dev_disable(), and superio_dev_enabled() functions are used to enable, disable, or check status of the device dev. The mask parameter selects sub-functions of a device that supports them. For devices that do not have sub-functions, mask should be set to 1.
The accessor interface
The superio_get_dma() is used to get a DMA channel number configured for the device dev.
The superio_get_iobase() is used to get a base I/O port configured for the device dev. The device may expose additional or alternative configuration access via the I/O ports.
The superio_get_irq() is used to get an interrupt number configured for the device dev.
The superio_get_ldn() is used to get a Logical Device Number of the device dev.
The superio_get_type() is used to get a type of the device dev.
