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.
