.PP
recover_bus
.RS 4
Recover routine\&. Either pass driver\*(Aqs
\fBrecover_bus\fR
routine, or
\fBi2c_generic_scl_recovery\fR
or
\fBi2c_generic_gpio_recovery\fR\&.
.RE
.PP
get_scl
.RS 4
This gets current value of SCL line\&. Mandatory for generic SCL recovery\&. Used internally for generic GPIO recovery\&.
.RE
.PP
set_scl
.RS 4
This sets/clears SCL line\&. Mandatory for generic SCL recovery\&. Used internally for generic GPIO recovery\&.
.RE
.PP
get_sda
.RS 4
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\&.
.RE
.PP
prepare_recovery
.RS 4
This will be called before starting recovery\&. Platform may configure padmux here for SDA/SCL line or something else they want\&.
.RE
.PP
unprepare_recovery
.RS 4
This will be called after completing recovery\&. Platform may configure padmux here for SDA/SCL line or something else they want\&.
.RE
.PP
scl_gpio
.RS 4
gpio number of the SCL line\&. Only required for GPIO recovery\&.
.RE
.PP
sda_gpio
.RS 4
gpio number of the SDA line\&. Only required for GPIO recovery\&.
