STRUCT I2C_CLIENT(9) I2C and SMBus Subsystem STRUCT I2C_CLIENT(9)NAMEstruct_i2c_client - represent an I2C slave device
SYNOPSIS
struct i2c_client {
unsigned short flags;
unsigned short addr;
char name[I2C_NAME_SIZE];
struct i2c_adapter * adapter;
struct i2c_driver * driver;
struct device dev;
int irq;
struct list_head detected;
};
MEMBERS
flags
I2C_CLIENT_TEN indicates the device uses a ten bit chip address;
I2C_CLIENT_PEC indicates it uses SMBus Packet Error Checking
addr
Address used on the I2C bus connected to the parent adapter.
name[I2C_NAME_SIZE]
Indicates the type of the device, usually a chip name that´s
generic enough to hide second-sourcing and compatible revisions.
adapter
manages the bus segment hosting this I2C device
driver
device´s driver, hence pointer to access routines
dev
Driver model device node for the slave.
irq
indicates the IRQ generated by this device (if any)
detected
member of an i2c_driver.clients list or i2c-core´s
userspace_devices list
DESCRIPTION
An i2c_client identifies a single device (i.e. chip) connected to an
i2c bus. The behaviour exposed to Linux is defined by the driver
managing the device.
