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.

Pull SoC devicetree updates from Arnd Bergmann: "A number of SoC platforms are adding modernized variants of their already supported chips time, with a total of 12 new SoCs, and two older SoC getting removed: - Qualcomm Glymur is a compute SoC using 18 Oryon-2 CPU cores - Qualcomm Mahua is a variant of Glymur with only 12 CPU cores, but largely identical. - Qualcomm Eliza is an embeded platform for mobile phone (SM7750) and IOT (QC7790S/M) workloads - Qualcomm IPQ5210 is a wireless networking SoC using Cortex-A53 cores - Qualcomm apq8084 and ipq806x had only rudimentary support but no actual products using them, so they are now gone. - Axis ARTPEC-9 is a follow-up to the ARTPEC-8 embedded SoC, using the Samsung SoC platform but now with Cortex-A55 cores - ARM Zena is a virtual platform in FVP using Cortex-A720AE cores, with additional versions planned to be merged in the future. - ARM corstone-1000-a320 is a reference platform for IOT, using low-end Cortex-A320 cores - Microchip LAN9691 is an updated 64-bit variant of the arm32 lan966x series of networking SoCs - Microchip PIC64GX is an embedded RISC-V chip using SIFIVE U54 CPU cores - Rockchip RV1103B is the low-end 32-bit single-core vision processor - Renesas RZ/G3L (r9a08g046) is an industrial embedded chip using Cortex-A55 cores, similar to the G3E and G3S variants we already supported. - NXP S32N79 is an automotive SoC using Cortex-A78AE cores, a significant upgrade from the older S32V and S32G series These all come with at least one reference board or an initial product using these, in total there are 67 newly added boards. The ones for already supported SoCs are: - Two more Aspeed BMC based boards - Three older tablets based on 32-bit OMAP4 and Exynos5 SoCs - One Set-top-box based on Allwinner H6 - 22 additional industrial/embedded boards using 64-bit NXP i.MX8M or i.MX9 SoCs - 20 Qualcomm SoC based machines across all possible markets: workstation, gaming, laptop, phone, networking, reference, ... - Three more Rockchips rk35xx based boards - Four variants of the Toradex Verdin using TI AM62 Other notable bits are: - A cleanup for the 32-bit Tegra paz00 board moved the last board specific code on Tegra into equivalent dts syntax. - There continues to be a significant number of fixes for static checking of dtc syntax, but it feels like this is slowing down, hopefully getting into a state where most known issues are addressed - Additional hardware support for many existing boards across SoC families, notably Qualcomm, Broadcom, i.MX2, i.MX6, Rockchips, STM32, Mediatek, Tegra, TI and Microchip" * tag 'soc-dt-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (841 commits) arm64: dts: ti: k3: Use memory-region-names for r5f ARM: dts: imx: Add DT overlays for DH i.MX6 DHCOM SoM and boards ARM: dts: imx6sx: remove fallback compatible string fsl,imx28-lcdif ARM: dts: imx25: rename node name tcq to touchscreen ARM: dts: imx: b850v3: Disable unused usdhc4 ARM: dts: imx: b850v3: Define GPIO line names ARM: dts: imx: b850v3: Use alphabetical sorting ARM: dts: imx: bx50v3: Configure phy-mode to eliminate a warning ARM: dts: imx: bx50v3: Configure switch PHY max-speed to 100Mbps ARM: dts: imx7ulp: Add CPU clock and OPP table support ARM: dts: imx7-mba7: Deassert BOOT_EN after boot ARM: dts: tqma7: add boot phase properties ARM: dts: imx7s: add boot phase properties ARM: dts: tqma6ul[l]: correct spelling of TQ-Systems ARM: dts: mba6ulx: add boot phase properties ARM: dts: imx6ul[l]-tqma6ul[l]: add boot phase properties ARM: dts: imx6ul/imx6ull: add boot phase properties ARM: dts: imx6qdl-mba6: add boot phase properties ARM: dts: imx6qdl-tqma6: add boot phase properties ARM: dts: imx6qdl: add boot phase properties ...

i.MX ARM device tree changes for 7.1: - Device Tree Schema Compliance Fixes Fixed numerous CHECK_DTBS warnings across multiple i.MX SoC families Renamed nodes to match schema requirements (tcq→touchscreen, uart8250→serial, iomuxc→pinmux, etc.). Fixed node naming conventions (added "led-" prefix, proper addressing formats). Corrected compatible strings and removed undocumented fallbacks. Added required properties (clocks, clock-names, power supplies, #sound-dai-cells). - New Hardware Support Added DT overlays for various expansion modules (i.MX6 DHCOM PDK2, PicoITX display boards). Added support for muRata 1YN WiFi chip (replacement for 1DX) on i.MX6ULL DHCOR board. i.MX7ULP: Added CPU clock and OPP table support for frequency scaling. - Boot Phase Properties Added bootph.yaml properties to multiple TQ-Systems boards and SoCs: imx7s, tqma7, mba7 imx6ul/ull, tqma6ul/ull, mba6ulx imx6qdl, tqma6, mba6. - Bug Fixes & Corrections Fixed interrupt property usage (interrupts→interrupts-extended where needed). Corrected spelling ("TQ-Systems" with hyphen). Removed redundant intermediate nodes in pinmux hierarchy.

Support for the RV1103B SoC and the Onion Omega4 board using it. While the RV1103B only got a B-extension to its name, the SoC internals were reworked heavily. So likely it's mainly pin compatible to the non-B variant.

Pull SoC fixes from Arnd Bergmann: "The largest part here are devicetree fixes for Qualcomm, and NXP i.MX, addressing a few regressions and incorrect settings in board and SoC pecific dts files. The largest single commits are a revert of a cleanup patch for i.MX that caused regressions for the NAND flash controller and a fixup for an incomplete cleanup of the PCIe controller on Qualcomm platforms that broke because the state was left incompatible with both the old and new behavior. On the Rockchips, Hisilicon, Renesas, Allwinner and AT91 platforms, only a single simple dts bugfix each was added since the last round of fixes. On the SoC specific device drivers, everything is relatively harmless: three reset controller driver fixes, a compatibility for fix ASpeed soc ID, and error handling fixes for Qualcomm and Microchip.

ARM: dts: imx6sx: remove fallback compatible string fsl,imx28-lcdif

2026-04-06T01:35:40+00:00

The i.MX6SX LCDIF is not fully compatible with the i.MX28 LCDIF. The i.MX6SX controller provides additional overlay registers (AS_CTRL) which are not present on i.MX28. Linux has supported the dedicated compatible string since commit 45d59d704080 ("drm: Add new driver for MXSFB controller"). Other known DT users such as U-Boot and Barebox already support "fsl,imx6sx-lcdif", so removing the fallback compatible string is low risk since this device is used for display output only.
