Merge tag 'asoc-v4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next
ASoC: Updates for v4.21 Not much work on the core this time around but we've seen quite a bit of driver work, including on the generic DT drivers. There's also a large part of the diff from a merge of the DaVinci and OMAP directories, along with some active development there: - Preparatory work from Morimoto-san for merging the audio-graph and audio-graph-scu cards. - A merge of the TI OMAP and DaVinci directories, the OMAP product line has been merged into the DaVinci product line so there is now a lot of IP sharing which meant that the split directories just got in the way. This has pulled in a few architecture changes as well. - A big cleanup of the Maxim MAX9867 driver from Ladislav Michl. - Support for Asahi Kaesi AKM4118, AMD ACP3x, Intel platforms with RT5660, Meson AXG S/PDIF inputs, several Qualcomm IPs and Xilinx I2S controllers.
