Merge tag 'asoc-v4.2' into asoc-rt5645
ASoC: Updates for v4.2 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.
