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.
