There were lots of times the stability of DT bindings was discussed, and I certainly have told people on the mailing list to keep their dtb updated while we are figuring out things like clock bindings and adding functionality. I'm sorry that it wasn't more clear. As has already been said in this thread, when the DT migration started, we didn't know how it should all look and work. It took time to figure out what was sane and what was not. g. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html From mboxrd@z Thu Jan 1 00:00:00 1970 From: grant.likely@secretlab.ca (Grant Likely) Date: Thu, 21 Nov 2013 18:16:08 +0000 Subject: ACPI vs DT at runtime In-Reply-To: <20131120064056.GB5272@netboy> References: <20131115095717.GC1709@e106331-lin.cambridge.arm.com> <5289A356. 4060004@jonmasters.org> <20131118150052.GC24408@sirena.org.uk> < 20131118191336.GB5886@quad.lixom.net> <20131119091216.GA4412@netboy> < 20131119184827.GD20967@quad.lixom.net> <20131120064056.GB5272@netboy> Message-ID: <20131121181608.1DDDCC406A3@trevor.secretlab.ca> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org On Wed, 20 Nov 2013 07:40:57 +0100, Richard Cochran wrote: > On Tue, Nov 19, 2013 at 10:48:27AM -0800, Olof Johansson wrote: > > > > This is just a tangent and a distraction anyway: You should know by > > now that we've decided to keep backwards compatibility going forward, > > so any argument about why we did it differently before is leading nowhere. > > Yes, I know it is tangent, but the tone in which you address people > (like Jon Masters) who complain about DT quality is really not fair. > > When DT for arm was first proposed, I argued against it in vain. > Since then, I have really, truly tried my best to keep on top of the > DT discussions on the arm list, because everyone working on the arm > platform will have to know DT intimately, whether they want to or not. > > Now, I never saw any proclamation or discussion about "DT is in flux" > on the arm list.
