STRUCT UIO_MEM(9) Device drivers infrastructure STRUCT UIO_MEM(9)NAME
struct_uio_mem - description of a UIO memory region
SYNOPSIS
struct uio_mem {
const char * name;
phys_addr_t addr;
unsigned long size;
int memtype;
void __iomem * internal_addr;
struct uio_map * map;
};
MEMBERS
name
name of the memory region for identification
addr
address of the device's memory (phys_addr is used since addr can be logical, virtual, or physical & phys_addr_t should always be large
enough to handle any of the address types)
size
size of IO
memtype
type of memory addr points to
internal_addr
ioremap-ped version of addr, for driver internal use
map
for use by the UIO core only.

STRUCT I2C_BOARD_INF(9) I2C and SMBus Subsystem STRUCT I2C_BOARD_INF(9)NAME
struct_i2c_board_info - template for device creation
SYNOPSIS
struct i2c_board_info {
char type[I2C_NAME_SIZE];
unsigned short flags;
unsigned short addr;
void * platform_data;
struct dev_archdata * archdata;
int irq;
};
MEMBERS
type[I2C_NAME_SIZE]
chip type, to initialize i2c_client.name
flags
to initialize i2c_client.flags
addr
stored in i2c_client.addr
platform_data
stored in i2c_client.dev.platform_data
archdata
copied into i2c_client.dev.archdata
irq
stored in i2c_client.irq
DESCRIPTION
I2C doesn't actually support hardware probing, although controllers and devices may be able to use I2C_SMBUS_QUICK to tell whether or not
there's a device at a given address. Drivers commonly need more information than that, such as chip type, configuration, associated IRQ,
and so on.
i2c_board_info is used to build tables of information listing I2C devices that are present. This information is used to grow the driver
model tree. For mainboards this is done statically using i2c_register_board_info; bus numbers identify adapters that aren't yet available.
For add-on boards, i2c_new_device does this dynamically with the adapter already known.
