Subject: [PATCH v6 03/19] platform/x86: intel_scu_ipc: Move legacy SCU IPC API to a separate header
Date: Mon, 17 Feb 2020 16:14:30 +0300 [thread overview]
Message-ID: <20200217131446.32818-4-mika.westerberg@linux.intel.com> (raw)
In-Reply-To: <20200217131446.32818-1-mika.westerberg@linux.intel.com>
In preparation for introducing a new API for SCU IPC, move the legacy
API and constants to a separate header that is is subject to be removed
eventually.
