Sorry to hear about that, maybe imx_pinctrl_probe_dt() should be
called before devm_pinctrl_register_and_init()?

Things got moved around a bit with e566fc11ea76 ("pinctrl: imx: use
generic pinctrl helpers for managing groups") it seems. But maybe that
was done because we did not have commit 950b0d91dc10 ("pinctrl: core:
Fix regression caused by delayed work for hogs") when the imx_pinctrl
changes got merged.

Gary, are you able to reproduce this? Seems it should happen with
any imx with hogs configured in the dts.

Regards,

Tony
