Merge tag 'asoc-v3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next
ASoC: Updates for v3.18 - More componentisation work from Lars-Peter, this time mainly cleaning up the suspend and bias level transition callbacks. - Real system support for the Intel drivers and a bunch of fixes and enhancements for the associated CODEC drivers, this is going to need a lot quirks over time due to the lack of any firmware description of the boards. - Jack detect support for simple card from Dylan Reid. - A bunch of small fixes and enhancements for the Freescale drivers. - New drivers for Analog Devices SSM4567, Cirrus Logic CS35L32, Everest Semiconductor ES8328 and Freescale cards using the ASRC in newer i.MX processors.
