STRUCT I2C_CLIENT(9) | I2C and SMBus Subsystem | STRUCT I2C_CLIENT(9) |
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¶
flagsI2C_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.COPYRIGHT¶
