The big thing this release has been Liam's addition of topology support to the core. We've also seen quite a bit of driver work and the continuation of Lars' refactoring for component support. - Support for loading ASoC topology maps from firmware, intended to be used to allow self-describing DSP firmware images to be built which can map controls added by the DSP to userspace without the kernel needing to know about individual DSP firmwares. - Lots of refactoring to avoid direct access to snd_soc_codec where it's not needed supporting future refactoring. - Big refactoring and cleanup serieses for the Wolfson ADSP and TI TAS2552 drivers. - Support for TI TAS571x power amplifiers. - Support for Qualcomm APQ8016 and ZTE ZX296702 SoCs. - Support for x86 systems with RT5650 and Qualcomm Storm. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJVddV1AAoJECTWi3JdVIfQQQsH/RG3lgOeot5jLWMsxJSKChEl KI+aaMcOw6Dj2LDccN8i6vUp8q44cKSXIc7lGLOzJW4K+OydCCGAvE+sJGyRE1dd yOHwcbvjJi4zFlt01RZchJ/Wa/S6zFucl5N9HxWsV4bEtfAA59IuhJLtospUlwsA mf9mpvSdeUAeh3lM2+AqAbXhTo6dYfD5ky5nrtpAkZjG8gqUG0u8Tpauja0lLcHi 72/3EkzKR6KHaefyPw3LdN+/H/YK79uHCVcctZnQg5xUUymcO16ReoTxKwV9cnDb lBJ6wO8RpUAO9evoG2Yj/l4p+czDCm5VkHMq0nPklHVRh7s/2PwKfox1aw4Pumg= =wolq -----END PGP SIGNATURE----- Merge tag 'asoc-v4.2' into asoc-next ASoC: Updates for v4.2 The big thing this release has been Liam's addition of topology support to the core.
