-Subject: [PATCH v3 1/2] bcma: register bcma as device tree driver
-
-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
-search for all the other cores.

-+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.
-+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:
-+
-+	axi@18000000 {
-+		compatible = "brcm,bus-axi";
-+		reg = <0x18000000 0x1000>;
-+		ranges = <0x00000000 0x18000000 0x00100000>;
-+		#address-cells = <1>;
-+		#size-cells = <1>;
-+
-+		pcie@12000 {
-+			reg = <0x00012000 0x1000>;
-+			interrupts = <GIC_SPI 131 IRQ_TYPE_LEVEL_HIGH>;
-+		};
-+
-+		ethernet@24000 {
-+			reg = <0x00024000 0x1000>;
-+			interrupts = <GIC_SPI 147 IRQ_TYPE_LEVEL_HIGH>;
-+		};
-+
-+		ethernet@25000 {
-+			reg = <0x00025000 0x1000>;
-+			interrupts = <GIC_SPI 148 IRQ_TYPE_LEVEL_HIGH>;
-+		};
-+	};
