If adding device tree support breaks existing platforms something is going wrong, while you're pulling things together device tree might not work until all the support makes it in but the old non-DT code should continue to function. > >There's also more than that, there's also at least Tero submitting some > >other stuff separately (and his stuff won't play with DT...) and I think > >Peter also.

Well, in this case everyone's only working on the regulator stuff, or at least only overlapping on that. The twl drivers aren't helping here - the structure is *very* non-standard and seems to make updates more fiddly than they should be as you're not just adding stuff to tables. Every update seems to need explicit code and per-change data adding which is making life harder. If things looked more standard from a code point of view it'd probably reduce the pain a lot. --CD/aTaZybdUisKIc Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAEBAgAGBQJPS5iOAAoJEBus8iNuMP3dVZoP/ips+5GHUCZRaYe3EV5rS4qH QVJf4yJgoqMWriTGXDnfv3AWmYmLyBgpQpQEjlKRxBChIknBd7m9jTp4Hlk/Or+u Qg07xE1Hit9iZtkJLSliiQYHOE1c1uIO+vuqoFNdXCT7HVALsNE+/T97ij2BlA+5 ZnZWDoJKVA0oDVT/I97URALcGdETHEVjtfj95X8bQU62At9Ji8MkaCihIXy18Q61 LQs/nqcApPwFQ6AvMGV0zWX/JkEn7lyFTWhk2Too2tzEr6iOcMKgdX8ZdAQoS2bd khB+SIm+xavebm18WSQmP96OZ1rH5/GnklxVoJc5narNbB2+TUqumeiscwtbeLTw Lmp/2nQMtFgllIoY5BHjOF4nkFOSnclD7ECnbZo6Yy1aaAzCfwk0yUE760MX9CnJ 74eg1sdFAi6Ud8QvxrRjEJd+KPBhFEufZfFS7GNnFJfVZkNhJ8asa/zcj6rENaMe xdP4F0binC47CaVzRak5KeWLAEvPvba0BEvlCQqPLLCoMbAfj5Qa4cf70mDRRCzX Z8eAfDEp4uyYMBnvMmiJAhJl4AJXjdxudSReuzNNMs81vVqpmfXFp6KVzIVZs5Nm 2l6nbNUVLVqEpjuqeorDMgeAFlEewB9RdeD7XHnVbf4i4D+0XhUm4+3m95RK1E/K EqvgMOoGnPZMsJld/UZU =rkNE -----END PGP SIGNATURE----- --CD/aTaZybdUisKIc-- --===============8494180855658223523== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ linaro-dev mailing list linaro-dev-cunTk1MwBs8s++Sfvej+rw@public.gmane.org http://lists.linaro.org/mailman/listinfo/linaro-dev --===============8494180855658223523==--
