+Device tree bindings for Allwinner A64 DE2 bus
+
+The Allwinner A64 DE2 is on a special bus, which needs a SRAM region (SRAM C)
+to be claimed for enabling the access.
+
+Required properties:
+
+ - compatible: Should contain "allwinner,sun50i-a64-de2"
+ - reg: A resource specifier for the register space
+ - #address-cells: Must be set to 1
+ - #size-cells: Must be set to 1
+ - ranges: Must be set up to map the address space inside the
+ DE2, for the sub-blocks of DE2.
+ - allwinner,sram: the SRAM that needs to be claimed
+
+Example:
+
+ de2@1000000 {
+ compatible = "allwinner,sun50i-a64-de2";
+ reg = <0x1000000 0x400000>;
+ allwinner,sram = <&de2_sram 1>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges = <0 0x1000000 0x400000>;
+
+ display_clocks: clock@0 {
+ compatible = "allwinner,sun50i-a64-de2-clk";
+ reg = <0x0 0x100000>;
+ clocks = <&ccu CLK_DE>,
+ <&ccu CLK_BUS_DE>;
+ clock-names = "mod",
+ "bus";
+ resets = <&ccu RST_BUS_DE>;
+ #clock-cells = <1>;
+ #reset-cells = <1>;
+ };
+ };
