1* Marvell Armada 7K/8K PCIe interface
2
3This PCIe host controller is based on the Synopsys DesignWare PCIe IP
4and thus inherits all the common properties defined in designware-pcie.txt.
5
6Required properties:
7- compatible: "marvell,armada8k-pcie"
8- reg: must contain two register regions
9   - the control register region
10   - the config space region
11- reg-names:
12   - "ctrl" for the control register region
13   - "config" for the config space region
14- interrupts: Interrupt specifier for the PCIe controler
15- clocks: reference to the PCIe controller clock
