From: Michal Simek
Date: Mon Mar 09 2015 - 04:41:27 EST

Initial version of device tree for Xilinx ZynqMP SoC.

Signed-off-by: Michal Simek <michal.simek@xxxxxxxxxx>
Acked-by: SÃren Brinkmann <soren.brinkmann@xxxxxxxxxx>
---

Changes in v3:
- Add the missing GIC maintenance interrupt
Reported-by Marc Zyngier <marc.zyngier@xxxxxxx>
- Fix PPI interrupt mask to reflect 4 cores
- Remove cortex-a9-gic compatible string and add arm,gic-400 one
Reported-by Mark Rutland

Changes in v2:
- move timer out of amba_apu bus because it is not on bus
Reported by Mark
- FIC GICC and GICV addresses - Reported by Rob
- Fix copyright
- Enable cadence IP in defconfig
- Add support for macb multiqueue
