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.
