ARM: dts: bcm4709: fix bus range assignment

2026-04-20T15:03:36+00:00

The netgear r8000 dts file limits the bus range for the first host bridge to exclude bus 0, but the two devices on the first bus are explicitly assigned to bus 0, causing a build time warning: /home/arnd/arm-soc/arch/arm/boot/dts/broadcom/bcm4709-netgear-r8000.dts:142.3-27: Warning (pci_device_bus_num): /axi@18000000/pcie@13000/pcie@0/pcie@0,0/pcie@1,0:bus-range: PCI bus number 0 out of range, expected (1 - 255) /home/arnd/arm-soc/arch/arm/boot/dts/broadcom/bcm4709-netgear-r8000.dts:142.3-27: Warning (pci_device_bus_num): /axi@18000000/pcie@13000/pcie@0/pcie@0,0/pcie@2,0:bus-range: PCI bus number 0 out of range, expected (1 - 255) As Rosen mentioned, the bus-range property was a mistake, so just remove it and keep the reg values pointing to bus 0, which is allowed by the default bus range of the SoC.

ARM: dts: broadcom: bcm2835-rpi: Move non simple-bus nodes to root level

2026-03-20T23:57:30+00:00

The 'gpu' and 'firmware' nodes are not MMIO devices, so they should not be under a 'simple-bus'. Additionally, the "raspberrypi,bcm2835-power" node is part of the firmware, so move it under the 'rpi-firmware' node.

ARM: dts: bcm63148: Add I2C block

2026-03-20T23:57:30+00:00

The BCM63148 has a brcmper I2C block. The peripheral range needs to be extended to accommodate it. The Boot LUT is at offset + 0x10000 so extend it to cover at least that too, 128 KB. INTERRUPT_ID_I2C is at (ISR_TABLE3_OFFSET + 19) = 96+19 = 115, convert back to SPI IRQ 115-32 = 83.
