enable_dev()

static void enable_dev ( struct device *  dev )

static

Create device structures and allocate resources to devices specified in the pnp_dev_info array (above).

Parameters

dev	Pointer to structure describing a Super I/O device.

Definition at line 52 of file superio.c.

lpc47n217_init()

static void lpc47n217_init ( struct device *  dev )

static

Initialize the specified Super I/O device.

Devices other than COM ports are ignored. For COM ports, we configure the baud rate.

Parameters

Configure the specified Super I/O device with the resources (I/O space, etc.) that have been allocate for it.

NOTE: Cannot use pnp_set_resources() here because it assumes chip support for logical devices, which the LPC47N217 doesn't have.
