Signed-off-by: Nicolas Saenz Julienne --- This will likely need a rebase once the RPi GENET patches land. Changes since v2: - Remove unused interrupt-map - correct dma-ranges to it's full size, non power of 2 bus DMA constraints now supported in linux-next[1] - add device_type - rename alias from pcie_0 to pcie0 Changes since v1: - remove linux,pci-domain [1] https://lkml.org/lkml/2019/11/21/235 arch/arm/boot/dts/bcm2711.dtsi | 41 ++++++++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+) diff --git a/arch/arm/boot/dts/bcm2711.dtsi b/arch/arm/boot/dts/bcm2711.dtsi index 667658497898..2e121fc8b3d0 100644 --- a/arch/arm/boot/dts/bcm2711.dtsi +++ b/arch/arm/boot/dts/bcm2711.dtsi @@ -288,6 +288,47 @@ IRQ_TYPE_LEVEL_LOW)>, arm,cpu-registers-not-fw-configured; }; + scb { + compatible = "simple-bus"; + #address-cells = <2>; + #size-cells = <1>; + + ranges = <0x0 0x7c000000 0x0 0xfc000000 0x03800000>, + <0x6 0x00000000 0x6 0x00000000 0x40000000>; + + pcie0: pcie@7d500000 { + compatible = "brcm,bcm2711-pcie"; + reg = <0x0 0x7d500000 0x9310>; + device_type = "pci"; + #address-cells = <3>; + #interrupt-cells = <1>; + #size-cells = <2>; + interrupts = , + ; + interrupt-names = "pcie", "msi"; + interrupt-map-mask = <0x0 0x0 0x0 0x7>; + interrupt-map = <0 0 0 1 &gicv2 GIC_SPI 143 + IRQ_TYPE_LEVEL_HIGH>; + msi-controller; + msi-parent = <&pcie0>; + + ranges = <0x02000000 0x0 0xf8000000 0x6 0x00000000 + 0x0 0x04000000>; + /* + * The wrapper around the PCIe block has a bug + * preventing it from accessing beyond the first 3GB of + * memory.
