Subject: [PATCH 12/12] thunderbolt: Add support for Intel Maple Ridge
Date: Thu, 19 Nov 2020 18:55:23 +0300 [thread overview]
Message-ID: <20201119155523.41332-13-mika.westerberg@linux.intel.com> (raw)
In-Reply-To: <20201119155523.41332-1-mika.westerberg@linux.intel.com>
Maple Ridge is first discrete USB4 host controller from Intel. It comes
with firmware based connection manager and the flows are similar as used
in Intel Titan Ridge.
