1 * Renesas RCar PCIe interface
4 - compatible: should contain one of the following
5 "renesas,pcie-r8a7779", "renesas,pcie-r8a7790", "renesas,pcie-r8a7791"
6 - reg: base address and length of the pcie controller registers.
7 - #address-cells: set to <3>
8 - #size-cells: set to <2>
9 - bus-range: PCI bus numbers covered
10 - device_type: set to "pci"
11 - ranges: ranges for the PCI memory and I/O regions.
12 - dma-ranges: ranges for the inbound memory regions.
13 - interrupts: two interrupt sources for MSI interrupts, followed by interrupt
14 source for hardware related interrupts (e.g. link speed change).
15 - #interrupt-cells: set to <1>
16 - interrupt-map-mask and interrupt-map: standard PCI properties
17 to define the mapping of the PCIe interface to interrupt
19 - clocks: from common clock binding: clock specifiers for the PCIe controller
21 - clock-names: from common clock binding: should be "pcie" and "pcie_bus".
