Subject: [PATCH 1/6] soundwire: qcom: add support to missing transport params
Date: Fri, 29 Jan 2021 17:32:43 +0000 [thread overview]
Message-ID: <20210129173248.5941-2-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <20210129173248.5941-1-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.
