-Amlogic Meson AXG DWC PCIE SoC controller
-
-Amlogic Meson PCIe host controller is based on the Synopsys DesignWare PCI core.
-It shares common functions with the PCIe DesignWare core driver and
-inherits common properties defined in
-Documentation/devicetree/bindings/pci/snps,dw-pcie.yaml.
-
-Additional properties are described here:
-
-Required properties:
-- compatible:
- should contain :
- - "amlogic,axg-pcie" for AXG SoC Family
- - "amlogic,g12a-pcie" for G12A SoC Family
- to identify the core.
-- reg:
- should contain the configuration address space.
-- reg-names: Must be
- - "elbi" External local bus interface registers
- - "cfg" Meson specific registers
- - "config" PCIe configuration space
-- reset-gpios: The GPIO to generate PCIe PERST# assert and deassert signal.
-- clocks: Must contain an entry for each entry in clock-names.
-- clock-names: Must include the following entries:
- - "pclk" PCIe GEN 100M PLL clock
- - "port" PCIe_x(A or B) RC clock gate
- - "general" PCIe Phy clock
-- resets: phandle to the reset lines.
-- reset-names: must contain "port" and "apb"
- - "port" Port A or B reset
- - "apb" Share APB reset
-- phys: should contain a phandle to the PCIE phy
-- phy-names: must contain "pcie"
-
-- device_type:
- should be "pci". As specified in snps,dw-pcie.yaml
-
-
-Example configuration:
-
- pcie: pcie@f9800000 {
- compatible = "amlogic,axg-pcie", "snps,dw-pcie";
- reg = <0x0 0xf9800000 0x0 0x400000
- 0x0 0xff646000 0x0 0x2000
- 0x0 0xf9f00000 0x0 0x100000>;
- reg-names = "elbi", "cfg", "config";
- reset-gpios = <&gpio GPIOX_19 GPIO_ACTIVE_HIGH>;
- interrupts = <GIC_SPI 177 IRQ_TYPE_EDGE_RISING>;
- #interrupt-cells = <1>;
- interrupt-map-mask = <0 0 0 0>;
- interrupt-map = <0 0 0 0 &gic GIC_SPI 179 IRQ_TYPE_EDGE_RISING>;
- bus-range = <0x0 0xff>;
- #address-cells = <3>;
- #size-cells = <2>;
- device_type = "pci";
- ranges = <0x82000000 0 0 0x0 0xf9c00000 0 0x00300000>;
-
- clocks = <&clkc CLKID_USB
- &clkc CLKID_PCIE_A
- &clkc CLKID_PCIE_CML_EN0>;
- clock-names = "general",
- "pclk",
- "port";
- resets = <&reset RESET_PCIE_A>,
- <&reset RESET_PCIE_APB>;
- reset-names = "port",
- "apb";
