+Marvell CCU address decoding bindings
+=====================================
+
+CCU configration driver (1st stage address translation) for Marvell Armada 8K and 8K+ SoCs.
+
+The CCU node includes a description of the address decoding configuration.
+
+Mandatory functions:
+ - marvell_get_ccu_memory_map
+ return the CCU windows configuration and the number of windows
+ of the specific AP.
+
+Mandatory structures:
+ ccu_memory_map - Array that includes the configuration of the windows
+ every window/entry is a struct which has 3 parameters:
+ - Base address of the window
+ - Size of the window
+ - Target-ID of the window
+
+Example:
+ struct addr_map_win ccu_memory_map[] = {
+ {0x00000000f2000000, 0x00000000e000000, IO_0_TID}, /* IO window */
+ };
