+Subject: [PATCH] PCI: imx6: add support for legacy irqs
+
+The i.MX6 supports legacy IRQ's via 155,154,153,152. When devices
+are behind a PCIe-to-PCIe switch (at least for the TI XIO2001) the
+mapping is reversed from when they are behind a PCIe switch.
+
+This patch still needs some review and clarification before going
+upstream.

+The driver reads the mac address from the device registers which would

+Subject: [PATCH] sky2: allow mac to come from dt
+
+The driver reads the mac address from the device registers which would
+need to have been programmed by the bootloader. This patch adds
+the ability to pull the mac from devicetree via the aliases/sky2 node.
