Keep it as is for the moment.

I don't think the API has been defined yet. But what has been
discussed is adding functions to struct phy_driver. The driver can
then implement whatever is needed to select a given page. There will
then be helpers which take the lock, select the page, do the
read/write, select page 0, and unlock.

Supporting this funny toggle should not be a problem.
