NAME
struct_i2c_client - represent an I2C slave deviceSYNOPSIS
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.
