I can't make use of the feature on the platform I had in mind, sadly. It doesn't really support switching from/to GPIO pinctrl states. If that ever changes, I will add bus recovery for that controller, but I think this is low priority. On the good side, there are patches which make i2c-mv64xxx another user of your new mechanism, so everything is well, I think.
