Subject: [PATCH v6 2/9] soundwire: qcom: add support to missing transport params
Date: Tue, 30 Mar 2021 15:47:12 +0100 [thread overview]
Message-ID: <20210330144719.13284-3-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <20210330144719.13284-1-srinivas.kandagatla@linaro.org>
Some of the transport parameters derived from device tree
are not fully parsed by the driver.
This patch adds support to parse those missing parameters.
