* Mobiveil AXI PCIe Root Port Bridge DT description
Mobiveil's GPEX 4.0 is a PCIe Gen4 root port bridge IP. This configurable IP
has up to 8 outbound and inbound windows for the address translation.
Required properties:
- #address-cells: Address representation for root ports, set to <3>
- #size-cells: Size representation for root ports, set to <2>
- #interrupt-cells: specifies the number of cells needed to encode an
interrupt source. The value must be 1.
- compatible: Should contain "mbvl,gpex40-pcie"
- reg: Should contain PCIe registers location and length
"config_axi_slave": PCIe controller registers
"csr_axi_slave" : Bridge config registers
"gpio_slave" : GPIO registers to control slot power
"apb_csr" : MSI registers
- device_type: must be "pci"
- apio-wins : number of requested apio outbound windows
default 2 outbound windows are configured -
1. Config window
2. Memory window
- ppio-wins : number of requested ppio inbound windows
default 1 inbound memory window is configured.
- bus-range: PCI bus numbers covered
- interrupt-controller: identifies the node as an interrupt controller
- #interrupt-cells: specifies the number of cells needed to encode an
interrupt source. The value must be 1.
- interrupt-parent : phandle to the interrupt controller that
it is attached to, it should be set to gic to point to
ARM's Generic Interrupt Controller node in system DT.
- interrupts: The interrupt line of the PCIe controller
last cell of this field is set to 4 to
denote it as IRQ_TYPE_LEVEL_HIGH type interrupt.
- interrupt-map-mask,
interrupt-map: standard PCI properties to define the mapping of the
PCI interface to interrupt numbers.
- ranges: ranges for the PCI memory regions (I/O space region is not
supported by hardware)
Please refer to the standard PCI bus binding document for a more
detailed explanation
