Well, it does happen from time to time; for example when moving from forcing some GPIOs on to making them software managed. It's only going to affect boards which were previously using regulators but not the fixed one, I'm not sure if that is common for these systems... > Well, I suspect, other boards must have had the same exact problem, as=20 > they added regulator support. It seems some boards to that, but not all... Handling this really needs some kind of "set on upgrade" thing but I'm not sure that's worth the trouble, especially since it's not that common. --yxUjl2uTvAeSG6i1 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAEBAgAGBQJP80kDAAoJEBus8iNuMP3dCZwQAIi7ymGcwtq5leQkBfU7Xovq mkn3abDpoC1qoxCLkQIhXcwOCVLzHQsJu8NGm7MT0Ye/dskSsmtdduB9CSm1dE5V u9TGtczjYHRwCsacM4OYQipvh+Js9uU9U/JM5SzyZe8IYNL+RnKdtWPvdqAv8K3b mYfAiRA7Y/JZdrG++sJK+JA3itrHmovSdZxvaJdljevuA2ZcPRP+QOXZE7A2Mwk0 E3eMCpAsx4J+Ol8FDlmyrexOpntMTO8UBV39zjsKtYbEsZj+2RxYKS6xWhPBExSN OzIpskxNoBH+EJwXUSbQ0ht9b/G9gqsNnH7clb5MM1Tvle2AF+qJWJjesBJBEiVT u5Ab9iH2n2HprlqRVmfg3IC05QaQP7DMlwnYmxk+6VC90FD28kzQ2iQaONl/0pbp ohkCTXMfl66oL7ZF4MuUtr7ZfZUotlIR0o1r77bDzTyPR6OU9SIK6qfF6MUQArIg x7d30lpj1QZTC8ZeSzeVRQ4DwMRu6xOf2FNGEBqcyWUjEvOLve1r3/vkZUrLByjE 9PsrLdqU5LwtnsOWf06iuJ8G923+NMHWbhsL/phanw4cmrIwtw3/DSTZgzkwkJCd nF6iM43OvFfx808635kPS0xtoCrurNJac1+6evrBxBjaBVewWDtItI7xJUCdXUul A3i30movw7XXl4cYqxeQ =V0vm -----END PGP SIGNATURE----- --yxUjl2uTvAeSG6i1--
