Subject: [PATCH v4 11/15] ASoC: dt-bindings: tegra: Add json-schema for Tegra audio graph card
Date: Fri, 16 Oct 2020 20:12:58 +0530
Message-ID: <1602859382-19505-12-git-send-email-spujar@nvidia.com> (raw)
In-Reply-To: <1602859382-19505-1-git-send-email-spujar@nvidia.com>

Add YAML schema for Tegra audio graph sound card DT bindings. It uses the
same DT bindings provided by generic audio graph driver. Along with this
few standard clock DT bindings are added which are specifically required
for Tegra audio.
