It's always a good idea to put the warnings in the commit message: arch/arm/boot/dts/r8a7790-lager.dtb: Warning (pci_bridge): Node /pci@ee090000/usb@0,1 node name is not "pci" or "pcie" arch/arm/boot/dts/r8a7790-lager.dtb: Warning (pci_bridge): Node /pci@ee090000/usb@0,1 missing ranges for PCI bridge (or not a bridge) arch/arm/boot/dts/r8a7790-lager.dtb: Warning (pci_bridge): Node /pci@ee090000/usb@0,1 incorrect #address-cells for PCI bridge arch/arm/boot/dts/r8a7790-lager.dtb: Warning (pci_bridge): Node /pci@ee090000/usb@0,1 incorrect #size-cells for PCI bridge arch/arm/boot/dts/r8a7790-lager.dtb: Warning (pci_bridge): Node /pci@ee090000/usb@0,1 missing bus-range for PCI bridge arch/arm/boot/dts/r8a7790-lager.dtb: Warning (pci_bridge): Node /pci@ee090000/usb@0,2 node name is not "pci" or "pcie" arch/arm/boot/dts/r8a7790-lager.dtb: Warning (pci_bridge): Node /pci@ee090000/usb@0,2 missing ranges for PCI bridge (or not a bridge) arch/arm/boot/dts/r8a7790-lager.dtb: Warning (pci_bridge): Node /pci@ee090000/usb@0,2 incorrect #address-cells for PCI bridge arch/arm/boot/dts/r8a7790-lager.dtb: Warning (pci_bridge): Node /pci@ee090000/usb@0,2 incorrect #size-cells for PCI bridge arch/arm/boot/dts/r8a7790-lager.dtb: Warning (pci_bridge): Node /pci@ee090000/usb@0,2 missing bus-range for PCI bridge arch/arm/boot/dts/r8a7790-lager.dtb: Warning (pci_bridge): Node /pci@ee0d0000/usb@0,1 node name is not "pci" or "pcie" arch/arm/boot/dts/r8a7790-lager.dtb: Warning (pci_bridge): Node /pci@ee0d0000/usb@0,1 missing ranges for PCI bridge (or not a bridge) arch/arm/boot/dts/r8a7790-lager.dtb: Warning (pci_bridge): Node /pci@ee0d0000/usb@0,1 incorrect #address-cells for PCI bridge arch/arm/boot/dts/r8a7790-lager.dtb: Warning (pci_bridge): Node /pci@ee0d0000/usb@0,1 incorrect #size-cells for PCI bridge arch/arm/boot/dts/r8a7790-lager.dtb: Warning (pci_bridge): Node /pci@ee0d0000/usb@0,1 missing bus-range for PCI bridge arch/arm/boot/dts/r8a7790-lager.dtb: Warning (pci_bridge): Node /pci@ee0d0000/usb@0,2 node name is not "pci" or "pcie" arch/arm/boot/dts/r8a7790-lager.dtb: Warning (pci_bridge): Node /pci@ee0d0000/usb@0,2 missing ranges for PCI bridge (or not a bridge) arch/arm/boot/dts/r8a7790-lager.dtb: Warning (pci_bridge): Node /pci@ee0d0000/usb@0,2 incorrect #address-cells for PCI bridge arch/arm/boot/dts/r8a7790-lager.dtb: Warning (pci_bridge): Node /pci@ee0d0000/usb@0,2 incorrect #size-cells for PCI bridge arch/arm/boot/dts/r8a7790-lager.dtb: Warning (pci_bridge): Node /pci@ee0d0000/usb@0,2 missing bus-range for PCI bridge arch/arm/boot/dts/r8a7790-lager.dtb: Warning (unit_address_format): Failed prerequisite 'pci_bridge' arch/arm/boot/dts/r8a7790-lager.dtb: Warning (pci_device_reg): Failed prerequisite 'pci_bridge' arch/arm/boot/dts/r8a7790-lager.dtb: Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge' The above indeed go away with your patch, but I don't know why ;-) > Signed-off-by: Rob Herring <robh@xxxxxxxxxx> > Cc: Simon Horman <horms@xxxxxxxxxxxx> > Cc: Magnus Damm <magnus.damm@xxxxxxxxx> > Cc: linux-renesas-soc@xxxxxxxxxxxxxxx > --- > Sub-arch maintainers, please apply to your trees unless arm-soc wants > to take the whole lot. > > arch/arm/boot/dts/r8a7790.dtsi | 16 ++++++---------- > arch/arm/boot/dts/r8a7791.dtsi | 16 ++++++---------- > arch/arm/boot/dts/r8a7794.dtsi | 16 ++++++---------- > 3 files changed, 18 insertions(+), 30 deletions(-) > > diff --git a/arch/arm/boot/dts/r8a7790.dtsi b/arch/arm/boot/dts/r8a7790.dtsi > index 6d10450de6d7..c16a37e9fb5d 100644 > --- a/arch/arm/boot/dts/r8a7790.dtsi > +++ b/arch/arm/boot/dts/r8a7790.dtsi > @@ -1598,16 +1598,14 @@ > 0x0800 0 0 1 &gic GIC_SPI 108 IRQ_TYPE_LEVEL_HIGH > 0x1000 0 0 2 &gic GIC_SPI 108 IRQ_TYPE_LEVEL_HIGH>; > > - usb@0,1 { > + usb@1,0 { > reg = <0x800 0 0 0 0>; > - device_type = "pci"; > phys = <&usb0 0>; > phy-names = "usb"; > }; Both Documentation/devicetree/bindings/pci/pci.txt and ePAPR refer to http://www.firmware.org/1275/bindings/pci/pci2_1.pdf http://www.firmware.org/1275/practice/imap/imap0_9d.pdf which no longer exist.
