Merge tag 'asoc-v4.3-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next
ASoC: Updates for v4.4 Not much core work here, a few small tweaks to interfaces but mainly the changes here are driver ones. Highlights include: - Updates to the topology userspace interface - Big updates to the Renesas support from Morimoto-san - Most of the support for Intel Sky Lake systems. - New drivers for Asahi Kasei Microdevices AK4613, Allwinnner A10, Cirrus Logic WM8998, Dialog DA7219, Nuvoton NAU8825 and Rockchip S/PDIF. - A new driver for the Atmel Class D speaker drivers
