[RFC v7 net-next 01/13] pinctrl: ocelot: allow pinctrl-ocelot to be loaded as a module

From: Colin Foster
Date: Sun Mar 06 2022 - 21:12:40 EST


Work is being done to allow external control of Ocelot chips. When pinctrl
drivers are used internally, it wouldn't make much sense to allow them to
be loaded as modules. In the case where the Ocelot chip is controlled
externally, this scenario becomes practical.
