arm64: tegra: Fix RTC aliases

2026-05-23T11:09:03+00:00

[ Upstream commit 69ec77b3f1074f3000d28f67f7629303e7999b84 ] The following warning is observed on the Tegra234 Jetson platforms ... rtc-nvidia-vrs10 4-003c: /aliases ID 0 not available This happens because the 'rtc@c2a0000' device is registered before the vrs10 RTC and so is assigned the 'rtc0' alias. We want the vrs10 RTC to be the default RTC because this RTC maintains time across power cycles. Fix this by adding a 'rtc1' alias for the 'rtc@c2a0000' device.

Pull SoC devicetree updates from Arnd Bergmann: "There are a handful of new SoCs this time, all of these are more or less related to chips in a wider family: - SpacemiT Key Stone K3 is an 8-core risc-v chip, and the first widely available RVA23 implementation. Note that this is entirely unrelated with the similarly named Texas Instruments K3 chip family that follwed the TI Keystone2 SoC. - The Realtek Kent family of SoCs contains three chip models rtd1501s, rtd1861b and rtd1920s, and is related to their earlier Set-top-box and NAS products such as rtd1619, but is built on newer Arm Cortex-A78 cores. - The Qualcomm Milos family includes the Snapdragon 7s Gen 3 (SM7635) mobile phone SoC built around Armv9 Kryo cores of the Arm Cortex-A720 generation. This one is used in the Fairphone Gen 6 - Qualcomm Kaanapali is a new SoC based around eight high performance Oryon CPU cores - NXP i.MX8QP and i.MX952 are both feature reduced versions of chips we already support, i.e. the i.MX8QM and i.MX952, with fewer CPU cores and I/O interfaces. As part of a cleanup, a number of SoC specific devicetree files got removed because they did not have a single board using the .dtsi files and they were never compile tested as a result: Samsung s3c6400, ST spear320s, ST stm32mp21xc/stm32mp23xc/stm32mp25xc, Renesas r8a779m0/r8a779m2/r8a779m4/r8a779m6/r8a779m7/r8a779m8/r8a779mb/ r9a07g044c1/r9a07g044l1/r9a07g054l1/r9a09g047e37, and TI am3703/am3715. All of these could be restored easily if a new board gets merged. Broadcom/Cavium/Marvell ThunderX2 gets removed along with its only machine, as all remaining users are assumed to be using ACPI based firmware. A relatively small number of 43 boards get added this time, and almost all of them for arm64. Aside from the reference boards for the newly added SoCs, this includes: - Three server boards use 32-bit ASpeed BMCs - One more reference board for 32-bit Microchip LAN9668 - 64-bit Arm single-board computers based on Amlogic s905y4, CIX sky1, NXP ls1028a/imx8mn/imx8mp/imx91/imx93/imx95, Qualcomm qcs6490/qrb2210 and Rockchip rk3568/rk3588s - Carrier board for SOMs using Intel agilex5, Marvell Armada 7020, NXP iMX8QP, Mediatek mt8370/mt8390 and rockchip rk3588 - Two mobile phones using Snapdragon 845 - A gaming device and a NAS box, both based on Rockchips rk356x On top of the newly added boards and SoCs, there is a lot of background activity going into cleanups, in particular towards getting a warning-free dtc build, and the usual work on adding support for more hardware on the previously added machines" * tag 'soc-dt-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (757 commits) dt-bindings: intel: Add Agilex eMMC support arm64: dts: socfpga: agilex: add emmc support arm64: dts: intel: agilex5: Add simple-bus node on top of dma controller node ARM: dts: socfpga: fix dtbs_check warning for fpga-region ARM: dts: socfpga: add #address-cells and #size-cells for sram node dt-bindings: altera: document syscon as fallback for sys-mgr arm64: dts: altera: Use lowercase hex dt-bindings: arm: altera: combine Intel's SoCFPGA into altera.yaml arm64: dts: socfpga: agilex5: Add IOMMUS property for ethernet nodes arm64: dts: socfpga: agilex5: add support for modular board dt-bindings: intel: Add Agilex5 SoCFPGA modular board arm64: dts: socfpga: agilex5: Add dma-coherent property arm64: dts: realtek: Add Kent SoC and EVB device trees dt-bindings: arm: realtek: Add Kent Soc family compatibles ARM: dts: samsung: Drop s3c6400.dtsi ARM: dts: nuvoton: Minor whitespace cleanup MAINTAINERS: Add Falcon DB arm64: dts: a7k: add COM Express boards ARM: dts: microchip: Drop usb_a9g20-dab-mmx.dtsi arm64: dts: rockchip: Fix rk3588 PCIe range mappings ...

arm64: tegra: smaug: Add usb-role-switch support

2026-01-17T00:15:26+00:00

The USB2 port on Smaug is configured for OTG operation but lacked the required 'usb-role-switch' property, leading to a failed probe and a non-functioning USB port. Add the property along with setting the default role to host. Signed-off-by: Diogo Ivo Signed-off-by: Thierry Reding

arm64: tegra: Correct CPU compatibles on Tegra264

2026-01-17T00:07:22+00:00

"arm,armv8" CPU compatible is only for software models and must not be used in DTS for actual hardware. Replace them with Neoverse V3AE compatible, based what is written on Wikipedia [1].

arm64: tegra: Drop unneeded status=okay on Tegra264

2026-01-17T00:07:22+00:00

Device nodes are enabled by default and this DTSI file does not include anything else, thus it is impossible that nodes were disabled before and need to be re-enabled. Adding redundant status=okay is just confusing and suggests some other code flow. Verified with dtx_diff. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Thierry Reding
