-Synopsys DesignWare Reset controller
-=======================================
-
-Please also refer to reset.txt in this directory for common reset
-controller binding usage.
-
-Required properties:
-
-- compatible: should be one of the following.
- "snps,dw-high-reset" - for active high configuration
- "snps,dw-low-reset" - for active low configuration
-
-- reg: physical base address of the controller and length of memory mapped
- region.
-
-- #reset-cells: must be 1.
-
-example:
-
- dw_rst_1: reset-controller@0000 {
- compatible = "snps,dw-high-reset";
- reg = <0x0000 0x4>;
- #reset-cells = <1>;
- };
-
- dw_rst_2: reset-controller@1000 {
- compatible = "snps,dw-low-reset";
- reg = <0x1000 0x8>;
- #reset-cells = <1>;
- };
