| 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. |
