As not all mach-imx platforms has support for run-time changes of pin configurations (such as LS1021A), a more selective approach to enabling pinctrl infrastructure makes sense, so that an e.g. an LS1021A only kernel could be built without pinctrl support. This is a very late follow up v1 3 years ago [1]. The situation seems to be unchanged since then, and I have tried to incorporate the requested changes.
