1 Device tree bindings for Allwinner A64 DE2 bus
3 The Allwinner A64 DE2 is on a special bus, which needs a SRAM region (SRAM C)
4 to be claimed for enabling the access.
8 - compatible: Should contain "allwinner,sun50i-a64-de2"
9 - reg: A resource specifier for the register space
10 - #address-cells: Must be set to 1
11 - #size-cells: Must be set to 1
12 - ranges: Must be set up to map the address space inside the
13 DE2, for the sub-blocks of DE2.
14 - allwinner,sram: the SRAM that needs to be claimed
