+Driver for ARM AXI Bus with Broadcom Plugins (bcma)
+
+Required properties:
+
+- compatible : brcm,bus-axi
+
+- reg : iomem address range of chipcommon core
+
+The cores on the AXI bus are automatically detected by bcma with the
+memory ranges they are using and they get registered afterwards.
+
+The top-level axi bus may contain children representing attached cores
+(devices). This is needed since some hardware details can't be auto
+detected (e.g. IRQ numbers). Also some of the cores may be responsible
+for extra things, e.g. ChipCommon providing access to the GPIO chip.
+
+Example:
+
+ axi@18000000 {
+ compatible = "brcm,bus-axi";
+ reg = <0x18000000 0x1000>;
+ ranges = <0x00000000 0x18000000 0x00100000>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ chipcommon {
+ reg = <0x00000000 0x1000>;
+
+ gpio-controller;
+ #gpio-cells = <2>;
+ };
+ };
