Putting on my U-Boot hat now, it's mostly unintentional and something in general (yes, the initial topic here is not such an example) we try and avoid, or use u-boot, as the prefix on as it's something that had been previously rejected or deemed inappropriate to be in the upstream version of the binding. But perhaps it's time to try and force the issue again, given what Rob and others have said in other parts of the thread. --=20 Tom --Y5U3e7U54RGuQ3mm Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAEBAgAGBQJZ55ZuAAoJEIf59jXTHXZS/zsQALR0lw2OwGhx/6uTExhOCIx5 C7rFyqbUtJayNjXZh5Qp6vGIdVkC7eNTinTyfKJ2Mq5bcv/KGh0kfxDj9CzB/8MA YfEQDxuGUAs4zALiUD6k4kTqWNhM7Sr6gEGUa4dTmZMXOiIwBIgiy3il6MaAJGHv SRcQZsXNUVAcxTXzUu628idbCtCmMUpFaPxSNET7KbjbjYqeiySEFDf1prMhzKvD bq0Q17Vf9ZPO+7jqb1GE9W6tlD4TL7X2oU+DTySrQgUlei6PelA4/MnciWGo82ik oezMUk6TtkmnUNzSYm9g55ZcyQEZyzlQd2kQ/9/SoBM3YkbQAqroDQ+LHHJWXqjN ElZANJU4CTdabTBHUilU74HAzXXB1A+/1keI6zJ0FE4c61v9x0jh5Kl7WZnfEdQY /kMyh+2mCBEVEIVM7znna/rOtVYU3jyhsUAbW84JlBfuLC4gr7zXN4kWe3a6BWWZ kt1OFJr0l2RCxBJ2kJC4o+MrHRsCqSx0bx9ujxmxV4O+SuTysE+Jkdxh2xbW/612 Cv7x1jabMYiWEfe8kbADoZldAiXTaSIvAzaLVW5DApDDwAK0ujEqriO9igHTelCq 3lhta8FekAp5yYd4bog5Q0uExaaJwCW4WNrlpyeXWKJjY0nUI8A/Ww+opF+OuTp7 +eC10pLJJGfMGv3Fkm11 =HSQB -----END PGP SIGNATURE----- --Y5U3e7U54RGuQ3mm-- From mboxrd@z Thu Jan 1 00:00:00 1970 From: Tom Rini Subject: Re: [Ksummit-discuss] Devicetree Workshop at Kernel Summit Prague (26 Oct 2017) Date: Wed, 18 Oct 2017 13:59:10 -0400 Message-ID: <20171018175910.GP12015@bill-the-cat> References: <20171017114823.58476908@bbrezillon> <20171018110958.mh76pngzluazmc7y@sirena.co.uk> Mime-Version: 1.0 Content-Type: multipart/signed; micalg=pgp-sha1; protocol="application/pgp-signature"; boundary="Y5U3e7U54RGuQ3mm" Return-path: Content-Disposition: inline In-Reply-To: <20171018110958.mh76pngzluazmc7y-7j8lgAiuQgnQXOPxS62xeg@public.gmane.org> Sender: devicetree-spec-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: Mark Brown Cc: Chen-Yu Tsai , Grant Likely , Kumar Gala , "ksummit-discuss-cunTk1MwBs98uUxBSJOaYoYkZiVZrdSR2LY78lusg7I@public.gmane.org" , Rob Herring , devicetree-spec-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, Pantelis Antoniou , "devicetree-u79uwXL29TY76Z2rM5mHXA@public.gmane.org" , Andy Gross , David Gibson , Lucas Stach List-Id: devicetree@vger.kernel.org --Y5U3e7U54RGuQ3mm Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable On Wed, Oct 18, 2017 at 12:09:58PM +0100, Mark Brown wrote: > On Wed, Oct 18, 2017 at 06:35:24PM +0800, Chen-Yu Tsai wrote: >=20 > > I'd like to add something on the topic of non-Linux projects.
