Merge tag 'asoc-v5.12' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v5.12 Another quiet release in terms of features, though several of the drivers got quite a bit of work and there were a lot of general changes resulting from Morimoto-san's ongoing cleanup work. - As ever, lots of hard work by Morimoto-san cleaning up the code and making it more consistent. - Many improvements in the Intel drivers including a wide range of quirks and bug fixes. - A KUnit testsuite for the topology code. - Support for Ingenic JZ4760(B), Intel AlderLake-P, DT configured nVidia cards, Qualcomm lpass-rx-macro and lpass-tx-macro - Removal of obsolete SIRF prima/atlas, Txx9 and ZTE zx drivers.
