-MediaTek Gen2 PCIe controller
-
-Required properties:
-- compatible: Should contain one of the following strings:
- "mediatek,mt2701-pcie"
- "mediatek,mt2712-pcie"
- "mediatek,mt7622-pcie"
- "mediatek,mt7623-pcie"
- "mediatek,mt7629-pcie"
- "airoha,en7523-pcie"
-- device_type: Must be "pci"
-- reg: Base addresses and lengths of the root ports.
-- reg-names: Names of the above areas to use during resource lookup.
-- #address-cells: Address representation for root ports (must be 3)
-- #size-cells: Size representation for root ports (must be 2)
-- clocks: Must contain an entry for each entry in clock-names.
- See ../clocks/clock-bindings.txt for details.
-- clock-names:
- Mandatory entries:
- - sys_ckN :transaction layer and data link layer clock
- Required entries for MT2701/MT7623:
- - free_ck :for reference clock of PCIe subsys
- Required entries for MT2712/MT7622:
- - ahb_ckN :AHB slave interface operating clock for CSR access and RC
- initiated MMIO access
- Required entries for MT7622:
- - axi_ckN :application layer MMIO channel operating clock
- - aux_ckN :pe2_mac_bridge and pe2_mac_core operating clock when
- pcie_mac_ck/pcie_pipe_ck is turned off
- - obff_ckN :OBFF functional block operating clock
- - pipe_ckN :LTSSM and PHY/MAC layer operating clock
- where N starting from 0 to one less than the number of root ports.
-- phys: List of PHY specifiers (used by generic PHY framework).
-- phy-names : Must be "pcie-phy0", "pcie-phy1", "pcie-phyN".. based on the
- number of PHYs as specified in *phys* property.
-- power-domains: A phandle and power domain specifier pair to the power domain
- which is responsible for collapsing and restoring power to the peripheral.
-- bus-range: Range of bus numbers associated with this controller.
-- ranges: Ranges for the PCI memory and I/O regions.
-
-Required properties for MT7623/MT2701:
-- #interrupt-cells: Size representation for interrupts (must be 1)
-- interrupt-map-mask and interrupt-map: Standard PCI IRQ mapping properties
- Please refer to the standard PCI bus binding document for a more detailed
- explanation.
-- resets: Must contain an entry for each entry in reset-names.
- See ../reset/reset.txt for details.
-- reset-names: Must be "pcie-rst0", "pcie-rst1", "pcie-rstN".. based on the
- number of root ports.
-
-Required properties for MT2712/MT7622/MT7629:
--interrupts: A list of interrupt outputs of the controller, must have one
- entry for each PCIe port
-- interrupt-names: Must include the following entries:
- - "pcie_irq": The interrupt that is asserted when an MSI/INTX is received
-- linux,pci-domain: PCI domain ID. Should be unique for each host controller
-
-In addition, the device tree node must have sub-nodes describing each
-PCIe port interface, having the following mandatory properties:
-
-Required properties:
-- device_type: Must be "pci"
-- reg: Only the first four bytes are used to refer to the correct bus number
- and device number.
-- #address-cells: Must be 3
-- #size-cells: Must be 2
-- #interrupt-cells: Must be 1
-- interrupt-map-mask and interrupt-map: Standard PCI IRQ mapping properties
- Please refer to the standard PCI bus binding document for a more detailed
- explanation.
-- ranges: Sub-ranges distributed from the PCIe controller node. An empty
- property is sufficient.
