+
+Marvell Device bus (localbus) configuration.
+============================================
+
+1. Properties for localbus nodes
+
+1.1 ranges
+
+Property: ranges
+
+Value type: <prop-encoded-array> encoded as arbitrary number of localbus
+ nodes specifiers.
+
+Description: ranges property defines values used for mapping devices
+ connected to localbus, in Marvell devices it is used also for
+ setting decoding windows.
+
+ a) child node address-cells:
+ - first cell: number of bank (chip select)
+ - second cell: (Marvell devices) Target ID for decoding
+ windows setup
+
+ b) parent node address cells:
+ - address offset: used with parent's node base address to
+ specify base address of mapped device
+
+ c) child node size-cells:
+ - size: defines amount of memory that should be reserved for
+ device
+
+1.2 bank-count
+
+Property: bank-count
+
+Value type: <u32>
+
+Description: The bank_count property defines maximum number of banks on
+ localbus node. Bank is most often interpreted as device chip
+ select, but may also describe another device (e.g. SPI flash).
+
+1.3 Example
+
+ localbus@0 {
+ #address-cells = <2>;
+ #size-cells = <1>;
+ compatible = "mrvl,lbc";
+ bank-count = <5>;
+
+ /* This reflects CPU decode windows setup. */
+ ranges = <0x0 0x2f 0xb2200000 0x00100000
+ 0x1 0x3e 0xb2100000 0x00100000
+ 0x2 0x3d 0xb0000000 0x02000000
+ 0x3 0x3b 0xb2000000 0x00100000>;
+ };
+
+2. Properties for localbus consumer nodes:
+
+2.1 reg
+
+Property: reg
+
+Value type: <prop-encoded-array>
+
+Description: A standard property required for localbus child nodes. Defines
+ the device memory region.
+
+ a) first cell: number of bank (chip select)
+
+ b) address offset: used with address offset from parent's ranges
+ for corresponding bank to specify base address of
+ the device
+
+ c) size: defines size of the device memory region
+
+2.2 Example
