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 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.
