Subject: [PATCH 2/6] soundwire: qcom: extract version field
Date: Fri, 29 Jan 2021 17:32:44 +0000 [thread overview]
Message-ID: <20210129173248.5941-3-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <20210129173248.5941-1-srinivas.kandagatla@linaro.org>
Extract version field to major, minor and step, so that we can add
dynamic version checks to read/writes.
This will help for controller versions that need specific bits
to be programmed.
