MEMBERS

21       recover_bus
22           Recover routine. Either pass driver's recover_bus routine, or
23           i2c_generic_scl_recovery or i2c_generic_gpio_recovery.
24
25       get_scl
26           This gets current value of SCL line. Mandatory for generic SCL
27           recovery. Used internally for generic GPIO recovery.
28
29       set_scl
30           This sets/clears SCL line. Mandatory for generic SCL recovery. Used
31           internally for generic GPIO recovery.
32
33       get_sda
34           This gets current value of SDA line. Optional for generic SCL
35           recovery. Used internally, if sda_gpio is a valid GPIO, for generic
36           GPIO recovery.
37
38       prepare_recovery
39           This will be called before starting recovery. Platform may
40           configure padmux here for SDA/SCL line or something else they want.
41
42       unprepare_recovery
43           This will be called after completing recovery. Platform may
44           configure padmux here for SDA/SCL line or something else they want.
45
46       scl_gpio
47           gpio number of the SCL line. Only required for GPIO recovery.
48
49       sda_gpio
50           gpio number of the SDA line. Only required for GPIO recovery.
