1Binding for the AXS10x reset controller
2
3This binding describes the ARC AXS10x boards custom IP-block which allows
4to control reset signals of selected peripherals. For example DW GMAC, etc...
5This block is controlled via memory-mapped register (AKA CREG) which
6represents up-to 32 reset lines.
7
8As of today only the following lines are used:
9 - DW GMAC - line 5
10
11This binding uses the common reset binding[1].

15Required properties:
16- compatible: should be "snps,axs10x-reset".
17- reg: should always contain pair address - length: for creg reset
18  bits register.
19- #reset-cells: from common reset binding; Should always be set to 1.

21Example:
22	reset: reset-controller@11220 {
23		compatible = "snps,axs10x-reset";
24		#reset-cells = <1>;
25		reg = <0x11220 0x4>;
26	};

28Specifying reset lines connected to IP modules:
29	ethernet@.... {
30		....
31		resets = <&reset 5>;
32		....
33	};
