Not really: http://mailman.alsa-project.org/pipermail/alsa-devel/2009-November/023425.html Sascha created imx-ssi because he didn't even notice my driver was already there! > I really doubt that missing device-tree on ARM platform is the only > reason resulting two ssi drivers. Yes, it is!

If you try to update the imx-ssi driver to support device trees, you'll have to convince the ASoC team to override my NAKs. -- Timur Tabi Linux kernel developer at Freescale
