* Amazon Annapurna Labs PCIe host bridge
|
|
Amazon's Annapurna Labs PCIe Host Controller is based on the Synopsys DesignWare
|
PCI core. It inherits common properties defined in
|
Documentation/devicetree/bindings/pci/designware-pcie.txt.
|
|
Properties of the host controller node that differ from it are:
|
|
- compatible:
|
Usage: required
|
Value type: <stringlist>
|
Definition: Value should contain
|
- "amazon,al-alpine-v2-pcie" for alpine_v2
|
- "amazon,al-alpine-v3-pcie" for alpine_v3
|
|
- reg:
|
Usage: required
|
Value type: <prop-encoded-array>
|
Definition: Register ranges as listed in the reg-names property
|
|
- reg-names:
|
Usage: required
|
Value type: <stringlist>
|
Definition: Must include the following entries
|
- "config" PCIe ECAM space
|
- "controller" AL proprietary registers
|
- "dbi" Designware PCIe registers
|
|
Example:
|
|
pcie-external0: pcie@fb600000 {
|
compatible = "amazon,al-alpine-v3-pcie";
|
reg = <0x0 0xfb600000 0x0 0x00100000

|
reg-names = "config", "controller", "dbi";
|
bus-range = <0 255>;
|
device_type = "pci";
|
#address-cells = <3>;
|
#size-cells = <2>;
|

|
interrupts = <GIC_SPI 49 IRQ_TYPE_LEVEL_HIGH>;
|
interrupt-map-mask = <0x00 0 0 7>;
|
interrupt-map = <0x0000 0 0 1 &gic GIC_SPI 41 IRQ_TYPE_LEVEL_HIGH>; /* INTa */
