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.
