Merge tag 'asoc-v4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v4.17 This is a *very* big release for ASoC. Not much change in the core but there s the transition of all the individual drivers over to components which is intended to support further core work. The goal is to make it easier to do further core work by removing the need to special case all the different driver classes in the core, many of the devices end up being used in multiple roles in modern systems. We also have quite a lot of new drivers added this month of all kinds, quite a few for simple devices but also some more advanced ones with more substantial code. - The biggest thing is the huge series from Morimoto-san which converted everything over to components. This is a huge change by code volume but was fairly mechanical - Many fixes for some of the Realtek based Baytrail systems covering both the CODECs and the CPUs, contributed by Hans de Goode. - Lots of cleanups for Samsung based Odroid systems from Sylwester Nawrocki. - The Freescale SSI driver also got a lot of cleanups from Nicolin Chen. - The Blackfin drivers have been removed as part of the removal of the architecture. - New drivers for AKM AK4458 and AK5558, several AMD based machines, several Intel based machines, Maxim MAX9759, Motorola CPCAP, Socionext Uniphier SoCs, and TI PCM1789 and TDA7419
