2025-05-05dt-bindings: net: ethernet-controller: Add informative text about RGMII delaysAndrew Lunn
Device Tree and Ethernet MAC driver writers often misunderstand RGMII delays. Rewrite the Normative section in terms of the PCB, is the PCB adding the 2ns delay. This meaning was previous implied by the definition, but often wrongly interpreted due to the ambiguous wording and looking at the definition from the wrong perspective. The new definition concentrates clearly on the hardware, and should be less ambiguous. Add an Informative section to the end of the binding describing in detail what the four RGMII delays mean. This expands on just the PCB meaning, adding in the implications for the MAC and PHY. Additionally, when the MAC or PHY needs to add a delay, which is software configuration, describe how Linux does this, in the hope of reducing errors. Make it clear other users of device tree binding may implement the software configuration in other ways while still conforming to the binding.

2025-05-06AsoC: Phase out hybrid PCI devresMark Brown
Merge series from Philipp Stanner <phasta@kernel.org>: A year ago we spent quite some work trying to get PCI into better shape. Some pci_ functions can be sometimes managed with devres, which is obviously bad. We want to provide an obvious API, where pci_ functions are never, and pcim_ functions are always managed. Thus, everyone enabling his device with pcim_enable_device() must be ported to pcim_ functions. Porting all users will later enable us to significantly simplify parts of the PCI subsystem. See here [1] for details. This patch series does that for sound. Feel free to squash the commits as you see fit. P. [1] https://elixir.bootlin.com/linux/v6.14-rc4/source/drivers/pci/devres.c#L18
2025-05-05docs: backlight: Clarify `actual_brightness`Mario Limonciello
Currently userspace software systemd treats `brightness` and `actual_brightness` identically due to a bug found in an out of tree driver. This however causes problems for in-tree drivers that use brightness to report user requested `brightness` and `actual_brightness` to report what the hardware actually has programmed. Clarify the documentation to match the behavior described in commit 6ca017658b1f9 ("[PATCH] backlight: Backlight Class Improvements").

2025-05-05saner calling conventions for ->d_automount()Al Viro
Currently the calling conventions for ->d_automount() instances have an odd wart - returned new mount to be attached is expected to have refcount 2. That kludge is intended to make sure that mark_mounts_for_expiry() called before we get around to attaching that new mount to the tree won't decide to take it out. finish_automount() drops the extra reference after it's done with attaching mount to the tree - or drops the reference twice in case of error. ->d_automount() instances have rather counterintuitive boilerplate in them. There's a much simpler approach: have mark_mounts_for_expiry() skip the mounts that are yet to be mounted. And to hell with grabbing/dropping those extra references. Makes for simpler correctness analysis, at that...

2025-05-05x86/CPU/AMD: Print the reason for the last resetYazen Ghannam
The following register contains bits that indicate the cause for the previous reset. PMx000000C0 (FCH::PM::S5_RESET_STATUS) This is useful for debug. The reasons for reset are broken into 6 high level categories. Decode it by category and print during boot. Specifics within a category are split off into debugging documentation. The register is accessed indirectly through a "PM" port in the FCH. Use MMIO access in order to avoid restrictions with legacy port access. Use a late_initcall() to ensure that MMIO has been set up before trying to access the register. This register was introduced with AMD Family 17h, so avoid access on older families. There is no CPUID feature bit for this register.

2025-05-02dt-bindings: media: renesas,isp: Add ISP core function blockNiklas Söderlund
Some R-Car ISP instances have in addition to the channel selector (CS) an ISP core (CORE) to perform operations on an image stream. The core function is mapped to a different memory region and has a separate interrupt than CS, extend the bindings to allow describing this. On the same SoC different instances of the ISP IP may have, or not have, the CORE functionality. The CS function on all instances on the SoC are the same and the documentation describes the full ISP (CS + CORE) as a single IP block. Where instances not having the CORE function simply lack the functionality to modify the image data. There are dependencies on the CS functionality while operating the CORE functionality. In order for the ISP core to function in memory-to-memory mode it needs to be feed input data from a Streaming Bridge interface. This interface is provided thru the VSP-X device. Add an optional new property "renesas,vspx" to provide a phandle to describe this relationship. While adding mandatory reg-names and interrupt-names breaks existing bindings the driver itself remains backward compatible and provides CS functionality if a single unnamed reg and interrupt property is present. Furthermore all existing users of the bindings are updated in following work to add these new mandatory properties.
