Subject: [PATCH 1/3] platform/x86/intel/tpmi: Add defines to get version information
Date: Mon, 25 Sep 2023 12:43:36 -0700 [thread overview]
Message-ID: <20230925194338.966639-2-srinivas.pandruvada@linux.intel.com> (raw)
In-Reply-To: <20230925194338.966639-1-srinivas.pandruvada@linux.intel.com>
Add defines to get major and minor version from a TPMI version field
value. This will avoid code duplication to convert in every feature
driver. Also add define for invalid version field.
