Merge tag 'asoc-v3.15-3' into asoc-next
ASoC: Updates for v3.15 A few more updates for the merge window: - Fixes for the simple-card DAI format DT mess. - A new driver for Cirrus cs42xx8 devices. - DT support for a couple more devices. - A revert of a previous buggy fix for soc-pcm, plus a few more fixes and cleanups. # gpg: Signature made Sun 23 Mar 2014 16:56:11 GMT using RSA key ID 7EA229BD # gpg: Good signature from "Mark Brown <broonie@sirena.org.uk>" # gpg: aka "Mark Brown <broonie@debian.org>" # gpg: aka "Mark Brown <broonie@kernel.org>" # gpg: aka "Mark Brown <broonie@tardis.ed.ac.uk>" # gpg: aka "Mark Brown <broonie@linaro.org>" # gpg: aka "Mark Brown <Mark.Brown@linaro.org>"
