Ah, if it's fixed by the board that's exactly the sort of thing that should be in DT - the DT describes the board so if some other system has a different configuration then it will have a different DT. With supply properties you can just leave them missing in the DT, you're not supposed to but so many systems do it that the framework will handle it. Otherwise if you want to represent VSYS you can have a fixed voltage regulator with no control and hook them up to it. --6Nae48J/T25AfBN4 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAl9E4wMACgkQJNaLcl1U h9Co+wf/Xf8KbC9/vFFir2BN6SL1tFkB0IvZMWZj1u+U08sPmTCIh2KRaC8xDJxI y6HF+I7FRWlcaj9ozuuNedPeXJi29wZC7BkgExRo31AMpx+SWE3blPoJit/M/YnI zk7ZAQKh63RF/Zaqk+drtruqz4w1yQ5vLXTLoQcbzk8YMTqfnUiBaNkFv1TCL1bq 0Qp6/LyejmL4sHZ2SF8WF0TvepxuR9EXGMB3cabyE+J8nw68QBisaHVFk99pVhul QIqvJOTMLq/XZeHklnt1rXdmHcIFzp0FUQyx6eek6b2nMjsSPlAtozQjFxZBl9Uw 1fiHa/CwqrgxU5Iv3JIuf+WM1tMNdw== =M9CH -----END PGP SIGNATURE----- --6Nae48J/T25AfBN4-- --===============7445152196278117848== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Linux-mediatek mailing list Linux-mediatek@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-mediatek --===============7445152196278117848==--
