Merge tag 'asoc-v6.4' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next
ASoC: Updates for v6.4 The bulk of the commits here are for the conversion of drivers to use void remove callbacks but there's a reasonable amount of other stuff going on, the pace of development with the SOF code continues to be high and there's a bunch of new drivers too: - More core cleanups from Morimto-san. - Update drivers to have remove() callbacks returning void, mostly mechanical with some substantial changes. - Continued feature and simplification work on SOF, including addition of a no-DSP mode for bringup, HDA MLink and extensions to the IPC4 protocol. - Hibernation support for CS35L45. - More DT binding conversions. - Support for Cirrus Logic CS35L56, Freescale QMC, Maxim MAX98363, nVidia systems with MAX9809x and RT5631, Realtek RT712, Renesas R-Car Gen4, Rockchip RK3588 and TI TAS5733.
