struct i2c_client(9)
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 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)
- 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.
