ST-Ericsson Ux500 boards
------------------------

Required properties (in root node) one of these:
	compatible = "st-ericsson,mop500" (legacy)
	compatible = "st-ericsson,u8500"

Required node (under root node):

soc: represents the system-on-chip and contains the chip
peripherals

Required property of soc node, one of these:
	compatible = "stericsson,db8500"

Required subnodes under soc node:

backupram: (used for CPU spin tables and for storing data
during retention, system won't boot without this):
	compatible = "ste,dbx500-backupram"

scu:
	see binding for arm/arm,scu.yaml

interrupt-controller:
	see binding for interrupt-controller/arm,gic.txt

timer:
	see binding for timer/arm,twd-timer.yaml

clocks:
	see binding for clocks/ux500.txt
