1Device tree bindings for Allwinner A64 DE2 bus
2
3The Allwinner A64 DE2 is on a special bus, which needs a SRAM region (SRAM C)
4to be claimed for enabling the access.
5
6Required properties:
7
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

16Example:
17
18	de2@1000000 {
19		compatible = "allwinner,sun50i-a64-de2";
20		reg = <0x1000000 0x400000>;
21		allwinner,sram = <&de2_sram 1>;
22		#address-cells = <1>;
23		#size-cells = <1>;
24		ranges = <0 0x1000000 0x400000>;
25
26		display_clocks: clock@0 {
27			compatible = "allwinner,sun50i-a64-de2-clk";
28			reg = <0x0 0x100000>;
29			clocks = <&ccu CLK_DE>,
30				 <&ccu CLK_BUS_DE>;
31			clock-names = "mod",
32				      "bus";
33			resets = <&ccu RST_BUS_DE>;
34			#clock-cells = <1>;
35			#reset-cells = <1>;
36		};
