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.
