Subject: [PATCH 15/22] xlink-ipc: Add xlink ipc device tree bindings
Date: Mon, 30 Nov 2020 15:07:00 -0800	[thread overview]
Message-ID: <20201130230707.46351-16-mgross@linux.intel.com> (raw)
In-Reply-To: <20201130230707.46351-1-mgross@linux.intel.com>

From: Seamus Kelly <seamus.kelly@intel.com>

Add device tree bindings for the xLink IPC driver which enables xLink to
control and communicate with the VPU IP present on the Intel Keem Bay
SoC.
