Shrug, just moving the fixed regulator to root also will do the job,
not sure simple-bus much sense here :(

you may be interested in include/dt-bindings/pinctrl/omap.h
OMAP3_CORE1_IOPAD, OMAP3_CORE2_IOPAD as needed here.

&omap3_pmx_core2 and OMAP3_CORE2_IOPAD probably here. and probably see
similar usage in other board dtsi.

I hope you have covered all required regulators here including the
ones you might need for IO.1P8 perhaps?

little curious as to why this. is that to override length 0x200 to
0x400? that belongs to soc.dtsi then.
