Merge tag 'asoc-v5.10' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v5.10 Not a huge amount going on in the core for ASoC this time but quite a lot of driver activity, especially for the Intel platforms: - Replacement of the DSP driver for some older x86 systems with a new one which was written with closer reference to the DSP firmware so should hopefully be more robust and maintainable. - A big batch of static checker and other fixes for the rest of the x86 DSP drivers. - Cleanup of the error unwinding code from Morimoto-san, hopefully making it more robust. - Helpers for parsing auxiluary devices from the device tree from Stephan Gerhold. - New support for AllWinner A64, Cirrus Logic CS4234, Mediatek MT6359 Microchip S/PDIF TX and RX controllers, Realtek RT1015P, and Texas Instruments J721E, TAS2110, TAS2564 and TAS2764
