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 {i
compatible = "snps,dw-low-reset";
reg = <0x1000 0x8>;
#reset-cells = <1>;
};
