NAME

struct_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 list;
   struct list_head detected;
   struct completion released;
 };

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)

list

list of active/busy clients (DEPRECATED)

detected

member of an i2c_driver.clients list

released

used to synchronize client releases & detaches and references

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.
