Merge tag 'asoc-v4.13' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v4.13 The big news with this release is the of-graph card, this provides a replacement for simple-card that is much more flexibile and scalable, allowing many more systems to use a generic sound card than was possible before: - The of-graph card, finally merged after a long and dedicated effort by Morimoto-san. - New widget types intended mainly for use with DSPs. - New drivers for Allwinner V3s SoCs, Ensonic ES8316, several classes of x86 machine, Rockchip PDM controllers, STM32 I2S and S/PDIF controllers and ZTE AUD96P22 CODECs.
