Merge tag 'asoc-v4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v4.18 This is a very big update, mainly due to a huge set of new drivers some of which are individually very large. We also have a lot of fixes for the topology stuff, several of the users have stepped up and fixed some the serious issues there, and continued progress on the transition away from CODEC specific drivers to generic component drivers. - Many fixes for the topology code, including fixes for the half done v4 ABI compatibility from Guenter Roeck and other ABI fixes from Kirill Marinushkin. - Lots of cleanup for Intel platforms based on Realtek CODECs from Hans de Goode. - More followups on removing legacy CODEC things and transitioning to components from Morimoto-san. - Conversion of OMAP DMA to the new, more standard SDMA-PCM driver. - A series of fixes and updates to the rather elderly Cirrus Logic SoC drivers from Alexander Sverdlin. - Qualcomm DSP support from Srinivas Kandagatla. - New drivers for Analog SSM2305, Atmel I2S controllers, Mediatek MT6351, MT6797 and MT7622, Qualcomm DSPs, Realtek RT1305, RT1306 and RT5668 and TI TSCS454
