-NXP LPC1850 Reset Generation Unit (RGU)
-========================================
-
-Please also refer to reset.txt in this directory for common reset
-controller binding usage.
-
-Required properties:
-- compatible: Should be "nxp,lpc1850-rgu"
-- reg: register base and length
-- clocks: phandle and clock specifier to RGU clocks
-- clock-names: should contain "delay" and "reg"
-- #reset-cells: should be 1
-
-See table below for valid peripheral reset numbers. Numbers not
-in the table below are either reserved or not applicable for
-normal operation.

- clock-names = "delay", "reg";
- #reset-cells = <1>;
-};
-
-Reset consumer example:
-mac: ethernet@...10000 {
- compatible = "nxp,lpc1850-dwmac", "snps,dwmac-3.611", "snps,dwmac";
- reg = <0x40010000 0x2000>;
