# struct\_i2c\_algo\_dp\_aux\_data(9)

driver interface structure for i2c over dp aux algorithm

## NAME

struct\_i2c\_algo\_dp\_aux\_data - driver interface structure for i2c over dp aux algorithm

## SYNOPSIS

```
struct i2c_algo_dp_aux_data {
  bool running;
  u16 address;
  int (* aux_ch) (struct i2c_adapter *adapter,int mode, uint8_t write_byte,uint8_t *read_byte);
};
```

## MEMBERS

running

set by the algo indicating whether an i2c is ongoing or whether the i2c bus is quiescent

address

i2c target address for the currently ongoing transfer

aux\_ch

driver callback to transfer a single byte of the i2c payload
