1 Device tree bindings for Allwinner DE2/3 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. The DE3 on Allwinner H6 is at the same
5 situation, and the binding also applies.
9 - compatible: Should be one of:
10 - "allwinner,sun50i-a64-de2"
11 - "allwinner,sun50i-h6-de3", "allwinner,sun50i-a64-de2"
12 - reg: A resource specifier for the register space
13 - #address-cells: Must be set to 1
14 - #size-cells: Must be set to 1
15 - ranges: Must be set up to map the address space inside the
16 DE2, for the sub-blocks of DE2.
17 - allwinner,sram: the SRAM that needs to be claimed
