+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.
|
|
+Automatic detection of the IRQ number is not working on
|
|
+BCM47xx/BCM53xx ARM SoCs. To assign IRQ numbers to the cores, provide
|
|
+them manually through device tree. Use an interrupt-map to specify the
|
|
+IRQ used by the devices on the bus. The first address is just an index,
|
|
+because we do not have any special register.

+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>;

|
|
+ #size-cells = <1>;
|
|
+ #interrupt-cells = <1>;
|
|
+ interrupt-map-mask = <0x000fffff 0xffff>;
|
|
+ interrupt-map =
|
