This driver is used by the bcm53xx ARM SoC code. Now it is possible to
give the address of the chipcommon core in device tree and bcma will

++Driver for ARM AXI Bus with Broadcom Plugins (bcma)
+
+Required properties:
+
-+- compatible : brcm,bus-aix
++- compatible : brcm,bus-axi
+
+- reg : iomem address range of chipcommon core
+
-+Optional properties:
-+
-+- sprom: reference to a sprom driver. This is needed for sprom less devices.
-+ Use bcm47xx_sprom for example.
-+
-+
-+The cores on the AIX bus are auto detected by bcma. Detection of the
-+IRQ number is not supported on BCM47xx/BCM53xx ARM SoCs, so it is
-+possible to provide the IRQ number over device tree. The IRQ number and
-+the device tree child entry will be added to the core with the matching
-+reg address.
++The cores on the AXI bus are automatically detected by bcma with the
++memory ranges they are using and they get registered afterwards.
++Automatic detection of the IRQ number is not reliable on
++BCM47xx/BCM53xx ARM SoCs. To assign IRQ numbers to the cores, provide
++them manually through device tree. The IRQ number and the device tree
++child entry will get assigned to the core with the matching reg address.
+
+Example:
+
-+ aix@18000000 {
-+ compatible = "brcm,bus-aix";
++ axi@18000000 {
++ compatible = "brcm,bus-axi";
+ reg = <0x18000000 0x1000>;
+ ranges = <0x00000000 0x18000000 0x00100000>;
+ #address-cells = <1>;
+ #size-cells = <1>;
-+ sprom = <&sprom0>;

-+ reg = <0x18024000 0x1000>;
-+ interrupts = <GIC_SPI 147 IRQ_TYPE_LEVEL_HIGH>;
