Merge tag 'asoc-v6.10' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v6.10 This is a very big update, in large part due to extensive work the Intel people have been doing in their drivers though it's also been busy elsewhere. There's also a big overhaul of the DAPM documentation from Luca Ceresoli arising from the work he did putting together his recent ELC talk, and he also contributed a new tool for visualising the DAPM state. - A new tool dapm-graph for visualising the DAPM state. - Substantial fixes and clarifications for the DAPM documentation. - Very large updates throughout the Intel audio drivers. - Cleanups of accessors for driver data, module labelling, and for constification. - Modernsation and cleanup work in the Mediatek drivers. - Several fixes and features for the DaVinci I2S driver. - New drivers for several AMD and Intel platforms, Nuvoton NAU8325, Rockchip RK3308 and Texas Instruments PCM6240.
