2026-01-17dt-bindings: clock: google,gs101-clock: Add DPU clock management unitPeter Griffin1-0/+19
Add dt schema documentation and clock IDs for the Display Process Unit (DPU) clock management unit (CMU). This CMU feeds IPs such as image scaler, enhancer and compressor.

2026-01-17x86/acpi: Add acpi=spcr to use SPCR-provided default consoleShenghao Yang1-0/+2
The SPCR provided console on x86 is only available as a boot console when earlycon is provided on the kernel command line, and will not be present in /proc/consoles. While it's possible to retain the boot console with the keep_bootcon parameter, that leaves the console using the less efficient 8250_early driver. Users wanting to use the firmware suggested console (to avoid maintaining unique serial console parameters for different server models in large fleets) with the conventional driver have to parse the kernel log for the console parameters and reinsert them.

So users can opt in to an automatic SPCR console, make ACPI init add it if acpi=spcr is set. ¹https://lore.kernel.org/lkml/20180118150951.28964-1-prarit@redhat.com/ [ bp: Touchups. ] Signed-off-by: Shenghao Yang <me@shenghaoyang.info> Signed-off-by: Borislav Petkov (AMD) <bp@alien8.de> Link: https://patch.msgid.link/20260117072827.355360-1-me@shenghaoyang.info

2026-01-16driver-core: improve driver binding documentationDanilo Krummrich1-3/+6
The driver binding documentation (still) mentions that "When a driver is attached to a device, the device is inserted into the driver's list of devices.". While it is true that the driver-core keeps track of all the devices that are attached to a driver, this is purely for internal purposes (i.e. it is an implementation detail) and has no relevance for user facing documentation. In fact, it is even misleading, since it could be read as if it were valid for driver implementations to keep track of all the devices bound to it. Instead, drivers operate on a per-device basis, with a separate per-device instance created when the driver is bound to a device. Hence, remove the mention of a driver's list of devices and instead add some documentation of the relationship between drivers and devices.

Document the serial communication interface (RSCI) used on the Renesas RZ/V2H(P) (R9A09G057) and RZ/V2N (R9A09G056) SoCs. These SoCs integrate the same RSCI IP block as the RZ/G3E (R9A09G047), so the RZ/G3E compatible is used as a fallback for both.

Convert the Android Goldfish QEMU Pipe binding to DT schema format. Move the file to the misc directory as it represents a miscellaneous communication device. Update the example node name to 'pipe' to comply with generic node naming standards and fix the mismatch between unit address and reg property in the original example.

2026-01-16dt-bindings: iommu: Add NVIDIA Tegra CMDQV supportAshish Mhetre2-1/+68
The Command Queue Virtualization (CMDQV) hardware is part of the SMMUv3 implementation on NVIDIA Tegra SoCs. It assists in virtualizing the command queue for the SMMU. Add a new device tree binding document for nvidia,tegra264-cmdqv. Also update the arm,smmu-v3 binding to include an optional nvidia,cmdqv property. This property is a phandle to the CMDQV device node, allowing the SMMU driver to associate with its corresponding CMDQV instance. Restrict this property usage to Nvidia Tegra264 only.

2026-01-16dt-bindings: memory: tegra: Document DBB clock for Tegra264Thierry Reding1-0/+13
Accesses to external memory are routed through the data backbone (DBB) on Tegra264. A separate clock feeds this path and needs to be enabled whenever an IP block makes an access to external memory. The external memory controller driver is the best place to control this clock since it knows how many devices are actively accessing memory. Document the presence of this clock on Tegra264 only.

No user of PHY fixups unregisters these. IOW: The fixup unregistering functions are unused and can be removed. Remove also documentation for these functions. Whilst at it, remove also mentioning of phy_register_fixup() from the Documentation, as this function has been static since ea47e70e476f ("net: phy: remove fixup-related definitions from phy.h which are not used outside phylib"). Fixup unregistering functions were added with f38e7a32ee4f ("phy: add phy fixup unregister functions") in 2016, and last user was removed with 6782d06a47ad ("net: usb: lan78xx: Remove KSZ9031 PHY fixup") in 2024.
