Merge tag 'asoc-v5.6' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v5.6 A pretty big release this time around, a lot of new drivers and both Morimoto-san and Takashi were doing subsystem wide updates as well: - Further big refactorings from Morimoto-san simplifying the core interfaces and moving things to the component level. - Transition of drivers to managed buffer allocation and removal of redundant PCM ioctls. - New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011, RT1015 and RT1308.
