NAME
struct_i2c_bus_recovery_info - I2C bus recovery information
SYNOPSIS
struct i2c_bus_recovery_info {
int (* recover_bus) (struct i2c_adapter *);
int (* get_scl) (struct i2c_adapter *);
void (* set_scl) (struct i2c_adapter *, int val);
int (* get_sda) (struct i2c_adapter *);
void (* prepare_recovery) (struct i2c_adapter *);
void (* unprepare_recovery) (struct i2c_adapter *);
int scl_gpio;
int sda_gpio;
};
MEMBERS
recover_bus
Recover routine. Either pass driver's recover_bus routine, or i2c_generic_scl_recovery
or i2c_generic_gpio_recovery.
get_scl
This gets current value of SCL line. Mandatory for generic SCL recovery. Used
internally for generic GPIO recovery.
set_scl
This sets/clears SCL line. Mandatory for generic SCL recovery. Used internally for
generic GPIO recovery.
get_sda
This gets current value of SDA line. Optional for generic SCL recovery. Used
internally, if sda_gpio is a valid GPIO, for generic GPIO recovery.
prepare_recovery
This will be called before starting recovery. Platform may configure padmux here for
SDA/SCL line or something else they want.
unprepare_recovery
This will be called after completing recovery. Platform may configure padmux here for
SDA/SCL line or something else they want.
scl_gpio
gpio number of the SCL line. Only required for GPIO recovery.
sda_gpio
gpio number of the SDA line. Only required for GPIO recovery.
