Subject: arm64: dts: rockchip: add ES8316 codec for ROCK Pi 4
X-Git-Tag: v6.6.17~8919^2~15^2~57
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=65bd2b8bdb3bddc37bea695789713916327e1c1f;p=platform%2Fkernel%2Flinux-rpi.git

arm64: dts: rockchip: add ES8316 codec for ROCK Pi 4

ROCK Pi 4 boards have the codec connected to i2s0 and it is accessible
via i2c1 address 0x11.
Add an audio-graph-card for it.
