-Subject: [PATCH 23/96] PCI: aardvark: Add clock support
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The IP relies on a gated clock. When we will add S2RAM support, this
-clock will need to be resumed before any PCIe registers are
-accessed. Add support for this clock.
