Merge tag 'asoc-v3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next
ASoC: Updates for v3.13 - Further work on the dmaengine helpers, including support for configuring the parameters for DMA by reading the capabilities of the DMA controller which removes some guesswork and magic numbers fromm drivers. - A refresh of the documentation. - Conversions of many drivers to direct regmap API usage in order to allow the ASoC level register I/O code to be removed, this will hopefully be completed by v3.14. - Support for using async register I/O in DAPM, reducing the time taken to implement power transitions on systems that support it.
