The pluggable modules on Cragganmore are going to be a problem for that, I have some ideas for a subsystem to handle the remapping generically but not had the time to actually do it yet. The stuff the BeagleBone guys were pushing wasn't suitable as it seemed like it was basically just a wrapper around DT which excludes non-DT platofrms. --Tcb1KvpfnM4LxW2s Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAEBAgAGBQJRUEyYAAoJELSic+t+oim9c6QQAJZmu35aO7Ik3X3DMS7yRV9I VHnMCvnXEGgAGt322DBfd7RcnW946GfTjoc8CerrN+3cbmH8vMmLO+vsIx5bHVj/ eQ6SM90aC17m48rdpOcce0ycWI0ZC7stmnjcMX96ZM5WfoxJ6L8bE3PFMLfGkzgJ G1iOuOgyK4veaIS/xUWaCYzrkI/XThmGetBpgVNsGX6zcRxDFF1VWn8VKIJWCKsO Q5dCHG0v/Qe241mcxuf0pkH2mirV/gruD9ou8yLUDIf1l+4ci0OaiDroxRQXTkag 9bWScnVL8DpyEajtTZQLitxwrIakLqO4meG45pmIEMjSL/jBhAWT2ZCvsybv5ae3 /N4jQmlGUomVlIjX8a9VKqGY1dUNSPRKBCU2fPh0jBlxkHWfS09Tv6YUoQQW4Yj5 Pe/kWxRs558jiTDJGo6JZ8Mk2alV8cmxukFTSvcQ95/P8TGPu9ZhBO6DkJFyUNXe AsEvorSqi5TOqLrSV1HMLurFQisHJf3/R+svZOB0Qhb0cqykiFJ5o0NRgwWAO2yg tG3JiWAqVPdYAtRdSev5jHsLBLU1OEWBDJDTGRZcDu2qJK6Cqt5YoMHXW3AzV6Rj VJJ1BPBz079J8rh3vVedg7fk3QvXQx38ue/ULpbUUsiewlwIvLDcXkTmoHv6jnbK E6Ig5Q+uIgud9t3a38xd =CRaX -----END PGP SIGNATURE----- --Tcb1KvpfnM4LxW2s-- From mboxrd@z Thu Jan 1 00:00:00 1970 From: broonie@opensource.wolfsonmicro.com (Mark Brown) Date: Mon, 25 Mar 2013 13:09:52 +0000 Subject: EXYNOS will support only DT from v3.10 In-Reply-To: <201303251237.38782.arnd@arndb.de> References: <17a501ce2948$17037610$450a6230$%kim@samsung.com> <20130325120256.GM18316@opensource.wolfsonmicro.com> <201303251237.38782.arnd@arndb.de> Message-ID: <20130325130951.GQ18316@opensource.wolfsonmicro.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org On Mon, Mar 25, 2013 at 12:37:38PM +0000, Arnd Bergmann wrote: > We don't have any DT support for S3C and S5P upstream yet, so I would > certainly agree on that.
