No, don't do this - introducing special snowflake bindings just makes things more complex at the system level and tells everyone else that they too can have special snowflake bindings. Someone should be able to connect up the regulators based purely on a schematic. Just describe the hardware, it's just one extra line in the DT per regulator. --ymtzczvnu5o364vi Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAlhGjVwACgkQJNaLcl1U h9Deuwf9EMNBFSbkQpzBHz80U/ptNcKxmD1CVN1JVpIH/Z16EA+Byjvvz/Vz8jwe HzHJEUZuf4//nlLy8M9XJdY0kUELdRncYGssm+7ZjJOJRw/zMtbuQ5u4d/GpvZTQ 7eOGiiXVSaPD+Fc93OJUuXD18jwazmaa1WWsOMIX895nH573XWhl2LfWBlHayxrw zCGn5i8bIMtmELfTqNI/V4D6TFnyz0OyB+Xkq7TzfMIEaEXOSuElxtVSpkx9cokD uemMRakYeenw5MV3Ln2ZMwbAgePZDzvuQ8B+3iBuG9ivnJjJ9LfX7aPV5KkeSP8w JEvu5aN6ZRLHDrsm2k5niCbuPF7R3Q== =0sZb -----END PGP SIGNATURE----- --ymtzczvnu5o364vi-- --===============1226658924== Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: base64 Content-Disposition: inline X19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX18KZHJpLWRldmVs IG1haWxpbmcgbGlzdApkcmktZGV2ZWxAbGlzdHMuZnJlZWRlc2t0b3Aub3JnCmh0dHBzOi8vbGlz dHMuZnJlZWRlc2t0b3Aub3JnL21haWxtYW4vbGlzdGluZm8vZHJpLWRldmVsCg== --===============1226658924==--
