STRUCT I2C_BUS_RECOV(9)	    I2C and SMBus Subsystem    STRUCT I2C_BUS_RECOV(9)

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_bus_recovery_info *bri);
	 void (* unprepare_recovery) (struct i2c_bus_recovery_info *bri);
	 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.
