Subject: [PATCH 05/25] thunderbolt: Convert PCIe adapter register names to follow the USB4 spec
Date: Wed, 23 Oct 2019 14:21:34 +0300 [thread overview]
Message-ID: <20191023112154.64235-6-mika.westerberg@linux.intel.com> (raw)
In-Reply-To: <20191023112154.64235-1-mika.westerberg@linux.intel.com>
Now that USB4 spec has names for these PCIe adapter registers we can use
them instead. This makes it easier to match certain register to the spec.
No functional changes.
