On some platforms, the sda/scl pins are muxed with gpio functions, so
they could be used for recovery. Select the gpio/default pin function
when prepare/unprepare recovery.
patch1 adds the missing scl-gpios, sda-gpios properties binding doc.
patch2 adds the pintrl property for i2c bus recovery.
patch3 selects gpio/default pin when prepare/unprepare recovery.
Since v2:
- add missing property dt-binding
Since v1:
- use IS_ERR_OR_NULL
