* 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
