From 9e0f86fdcdab6a0e183ad4ec2410453985b4cf3c Mon Sep 17 00:00:00 2001 From: Sameer Pujar Date: Tue, 19 Jan 2021 14:58:11 +0530 Subject: [PATCH] ASoC: dt-bindings: tegra: Add graph bindings Add device tree binding properties of generic graph to ASoC component devices. This allows to define audio ports out of these components or DAIs and audio graph based sound card can be realised with this.
