* Marvell Armada 7K/8K PCIe interface
This PCIe host controller is based on the Synopsis Designware PCIe IP
and thus inherits all the common properties defined in designware-pcie.txt.
Required properties:
- compatible: "marvell,armada8k-pcie"
- reg: must contain two register regions
- the control register region
- the config space region
- reg-names:
- "ctrl" for the control register region
- "config" for the config space region
- interrupts: Interrupt specifier for the PCIe controler
- clocks: reference to the PCIe controller clock
Example:
pcie@f2600000 {
compatible = "marvell,armada8k-pcie", "snps,dw-pcie";
reg = <0 0xf2600000 0 0x10000>, <0 0xf6f00000 0 0x80000>;
reg-names = "ctrl", "config";
#address-cells = <3>;
#size-cells = <2>;
#interrupt-cells = <1>;
device_type = "pci";
dma-coherent;
bus-range = <0 0xff>;
ranges = <0x81000000 0 0xf9000000 0 0xf9000000 0 0x10000 /* downstream I/O */
0x82000000 0 0xf6000000 0 0xf6000000 0 0xf00000>; /* non-prefetchable memory */
interrupt-map-mask = <0 0 0 0>;
interrupt-map = <0 0 0 0 &gic 0 GIC_SPI 32 IRQ_TYPE_LEVEL_HIGH>;
interrupts = <GIC_SPI 32 IRQ_TYPE_LEVEL_HIGH>;
num-lanes = <1>;
clocks = <&cpm_syscon0 1 13>;
