This contains pretty many small commits covering fairly large range of files in sound/ directory. Partly because of additional API support and partly because of constantly developed ASoC and ARM stuff. Some highlights: - Introduced the helper function and documentation for exposing the channel map via control API, as discussed in Plumbers; most of PCI drivers are covered, will follow more drivers later - Most of drivers have been replaced with the new PM callbacks (if the bus is supported) - HD-audio controller got the support of runtime PM and the support of D3 clock-stop. Also changing the power_save option in sysfs kicks off immediately to enable / disable the power-save mode. - Another significant code change in HD-audio is the rewrite of firmware loading code. Other than that, most of changes in HD-audio are continued cleanups and standardization for the generic auto parser and bug fixes (HBR, device-specific fixups), in addition to the support of channel-map API. - Addition of ASoC bindings for the compressed API, used by the mid-x86 drivers. - Lots of cleanups and API refreshes for ASoC codec drivers and DaVinci. - Conversion of OMAP to dmaengine. - New machine driver for Wolfson Microelectronics Bells. - New CODEC driver for Wolfson Microelectronics WM0010. - Enhancements to the ux500 and wm2000 drivers - A new driver for DA9055 and the support for regulator bypass mode. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) iQIcBAABAgAGBQJQcpeWAAoJEGwxgFQ9KSmkpi4P/2etDDz5aEkEHNa1l4xEmFcm ymiGTgjaalqpUAVbM/gYx9G59EFMEbzUl1BHAqE5La4wO/v9lNPb+VrdUo+B+NZ7 WSxIPWcNqdinSuoSqyYPjoPMVnhs3EMtNOqmf4jm1JOvdqA+4rO29xQVAqK/5Gfu LpMOyPiRi5ODnbQ1BOIWwpKICioY/mLwGJudK3z0i/fYVA7gLub20f+w+sOjKIA4 wmwQAMTjAR798Cg/tVy4fQmf4SLw+c2nIgGe/PD+2gVlGXLNKBrJfMonHPTbmwKu lmJO/EtnijNOnpbn6up7ryUQ9cSoZAUZOfdIOgmAeQgQ/LWR0f+zf2IQehSPwrul g6hqOnQI2DNN7ugT3cYVbYnsh56TjyhnxhhxZgkapqh706QkqHGyKJNMRetzuXmP 1O//MnZJrFQWd6sOKLlTL2ZzRvnxEJcNVGaE6bbwZTfQMtPeo9l1842uIq1dLUtG VxZb/svKUkMXv4is1dwUYUkpDsKxsgMEmabmuovceGf2N7jj/irkXgqxf6LWkaY1 JQ7ZFWUJyDzEMXRaFfzdGO15T532CfB84wvFX5xoPMwMste2AA7QuybFBVstXhKu AtKNDgRJFUTlnLIxydpPBWdWH3UJdEaFwwsSfuNKI8OmmGKhWC/aP83k4hzueu9H KYLvY/0ObMSMqiwh/ndQ =uNqD -----END PGP SIGNATURE----- Merge tag 'sound-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "This contains pretty many small commits covering fairly large range of files in sound/ directory.
