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/scu.txt
interrupt-controller:
see binding for interrupt-controller/arm,gic.txt
timer:
see binding for timer/arm,twd.txt
clocks:
see binding for clocks/ux500.txt
