DESCRIPTION

The bus_set_resource function sets the start address of the resource type, rid pair to be count long. Typically, client drivers do not use this interface. Bus drivers, however, often use it to set up the resources a client driver uses.

The arguments are as follows:

dev The device to set the resource on.
type The type of resource you want to allocate. It is one of:

SYS_RES_IRQ for IRQs
SYS_RES_DRQ for ISA DMA lines
SYS_RES_IOPORT for I/O ports
SYS_RES_MEMORY for I/O memory
rid A bus-specific handle that identifies the resource being allocated.
start The start address of this resource.
count The length of the resource. For example, the size of the memory in bytes.

RETURN VALUES

Zero is returned on success, otherwise an error is returned.
