Subject: [PATCH v1 1/2] ASoC: qcom: dt-bindings: Add SM8250 sound card bindings
Date: Mon, 26 Oct 2020 17:09:46 +0000	[thread overview]
Message-ID: <20201026170947.10567-2-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <20201026170947.10567-1-srinivas.kandagatla@linaro.org>

This patch adds bindings required for SM8250 based soundcards
for example Qualcomm Robotics RB5 Development Kit which makes
use of ADSP and Internal LPASS codec.
