Are not enough for some SoCs to have a working recovery.
Some need:

scl-gpio = <>;
sda-gpio = <>;
pinctrl-names = "default", "recovery";
pinctrl-0 = <&i2c_pins_hw>;
pinctrl-1 = <&i2c_pins_gpio>;

The driver was not filling rinfo->pinctrl with the device node
pinctrl data which is needed by generic recovery code.

V3 -> V4:
* Replace `else if` by simply `if`.
You forgot my tag. Why?
Woops sorry, I am not used to sending patches upstream. I didn't know I had to add the ack tag. Will do it!
Also I think this will generate more code and more noise in debug case.
So, I admit I gave a bad suggestion in previous round.
Ah yes you are right in case of dbg+CONFIG_PINCTRL not set it will print both messages but just one is enough.

Please, go for v3 with my tag (as v5).

Ok, I'll also add `i2c: designware: ` to $subject as Mika Westerberg suggested.

Thanks,
