+Subject: [PATCH] ARM: dts: BCM5301X: add root pcie bridges
+
+They are always required and instead of duplicating a definition in each
+dts file, place it in dtsi with labels and work based on that.
+
+Also changed each bridge@ to pcie@ to get extra dtc static analysis.
+
+Fixed bridge numbers as a result.
