Subject: [RFC PATCH 2/2] soundwire: qcom: add support for static port mapping
Date: Wed, 20 Jan 2021 18:01:10 +0000	[thread overview]
Message-ID: <20210120180110.8357-3-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <20210120180110.8357-1-srinivas.kandagatla@linaro.org>

On some of Qualcomm SoundWire controller instances ports are statically
mapped based on the functionalities. So add support for such mapping.
