Merge tag 'asoc-v3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v3.17 This has been a pretty exciting release in terms of the framework, we've finally got support for multiple CODECs attached to a single DAI link which has been something there's been interest in as long as I've been working on ASoC. A big thanks to Benoit and Misael for their work on this. Otherwise it's been a fairly standard release for development, including more componentisation work from Lars-Peter and a good selection of both CODEC and CPU drivers. - Support for multiple CODECs attached to a single DAI, enabling systems with for example multiple DAC/speaker drivers on a single link, contributed by Benoit Cousson based on work from Misael Lopez Cruz. - Support for byte controls larger than 256 bytes based on the use of TLVs contributed by Omair Mohammed Abdullah. - More componentisation work from Lars-Peter Clausen. - The remainder of the conversions of CODEC drivers to params_width() - Drivers for Cirrus Logic CS4265, Freescale i.MX ASRC blocks, Realtek RT286 and RT5670, Rockchip RK3xxx I2S controllers and Texas Instruments TAS2552. - Lots of updates and fixes, especially to the DaVinci, Intel, Freescale, Realtek, and rcar drivers.
