2025-07-24mfd: axp20x: Set explicit ID for AXP313 regulatorChen-Yu Tsai
On newer boards featuring the A523 SoC, the AXP323 (related to the AXP313) is paired with the AXP717 and serves as a secondary PMIC providing additional regulator outputs. However the MFD cells are all registered with PLATFORM_DEVID_NONE, which causes the regulator cells to conflict with each other. Commit e37ec3218870 ("mfd: axp20x: Allow multiple regulators") attempted to fix this by switching to PLATFORM_DEVID_AUTO so that the device names would all be different, however that broke IIO channel mapping, which is also tied to the device names. As a result the change was later reverted. Instead, here we attempt to make sure the AXP313/AXP323 regulator cell does not conflict by explicitly giving it an ID number. This was previously done for the AXP809+AXP806 pair used with the A80 SoC.

2025-07-24mfd: cros_ec: Separate charge-control probing from USB-PDThomas Weißschuh
The charge-control subsystem in the ChromeOS EC is not strictly tied to its USB-PD subsystem. Since commit 7613bc0d116a ("mfd: cros_ec: Don't load charger with UCSI") the presence of EC_FEATURE_UCSI_PPM would inhibit the probing of the charge-control driver. Furthermore recent versions of the EC firmware in Framework laptops hard-disable EC_FEATURE_USB_PD to avoid probing cros-usbpd-charger, which then also breaks cros-charge-control. Instead use the dedicated EC_FEATURE_CHARGER.

2025-07-24gpio: Add new gpio-macsmc driver for Apple MacsHector Martin
This driver implements the GPIO service on top of the SMC framework on Apple Mac machines. In particular, these are the GPIOs present in the PMU IC which are used to control power to certain on-board devices. Although the underlying hardware supports various pin config settings (input/output, open drain, etc.), this driver does not implement that functionality and leaves it up to the firmware to configure things properly. We also don't yet support interrupts/events. This is sufficient for device power control, which is the only thing we need to support at this point. More features will be implemented when needed. To our knowledge, only Apple Silicon Macs implement this SMC feature.

2025-07-24mfd: Add Apple Silicon System Management ControllerSven Peter
The System Management Controller (SMC) on Apple Silicon machines is a piece of hardware that exposes various functionalities such as temperature sensors, voltage/power meters, shutdown/reboot handling, GPIOs and more. Communication happens via a shared mailbox using the RTKit protocol which is also used for other co-processors. The SMC protocol then allows reading and writing many different keys which implement the various features. The MFD core device handles this protocol and exposes it to the sub-devices. Some of the sub-devices are potentially also useful on pre-M1 Apple machines and support for SMCs on these machines can be added at a later time.

The adp5589 support is based on legacy platform data and there's no upstream platform using this device. Moreover, recently, with commit 480a8ad683d7 ("mfd: adp5585: Add Analog Devices ADP5585 core support") we overlapped support for the adp5585 device (gpiochip part of it) but since it actually makes sense for the device to be supported under MFD, we can complement it and add the keymap support for it (properly based on FW properties).

2025-07-01mfd: adp5585: Refactor how regmap defaults are handledNuno Sá
The only thing changing between variants is the regmap default registers. Hence, instead of having a regmap configuration for every variant (duplicating lots of fields), add a chip info type of structure with a regmap ID to identify which defaults to use and populate regmap_config at runtime given a template plus the id. Also note that between variants, the defaults can be the same which means the chip info structure can be used in more than one compatible. This will also make it simpler adding new chips with more variants. Also note that the chip info structures are deliberately not const as they will also contain lots of members that are the same between the different devices variants and so we will fill those at runtime.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull irq fix from Thomas Gleixner: "A single fix for the PCI/MSI code: The conversion to per device MSI domains created a MSI domain with size 1 instead of sizing it to the maximum possible number of MSI interrupts for the device. This "worked" as the subsequent allocations resized the domain, but the recent change to move the prepare() call into the domain creation path broke this works by chance mechanism. Size the domain properly at creation time" * tag 'irq-urgent-2025-06-08' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: PCI/MSI: Size device MSI domain with the maximum number of vectors

loongson_laptop_turn_{on,off}_backlight() are designed for controlling the power of the backlight, but they aren't really used in the driver previously. Unify these two functions since they only differ in arguments passed to ACPI method, and wire up loongson_laptop_backlight_update() to update the power state of the backlight as well. Tested on the TongFang L860-T2 Loongson-3A5000 laptop.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb Pull USB / Thunderbolt updates from Greg KH: "Here is the big set of USB and Thunderbolt changes for 6.16-rc1. Included in here are the following: - USB offload support for audio devices. I think this takes the record for the most number of patch series (30+) over the longest period of time (2+ years) to get merged properly. Many props go to Wesley Cheng for seeing this effort through, they took a major out-of-tree hacked-up-monstrosity that was created by multiple vendors for their specific devices, got it all merged into a semi-coherent set of changes, and got all of the different major subsystems to agree on how this should be implemented both with changes to their code as well as userspace apis, AND wrangled the hardware companies into agreeing to go forward with this, despite making them all redo work they had already done in their private device trees. This feature offers major power savings on embedded devices where a USB audio stream can continue to flow while the rest of the system is sleeping, something that devices running on battery power really care about. There are still some more small tweaks left to be done here, and those patches are still out for review and arguing among the different hardware companies, but this is a major step forward and a great example of how to do upstream development well. - small number of thunderbolt fixes and updates, things seem to be slowing down here (famous last words...) - xhci refactors and reworking to try to handle some rough corner cases in some hardware implementations where things don't always work properly - typec driver updates - USB3 power management reworking and updates - Removal of some old and orphaned UDC gadget drivers that had not been used in a very long time, dropping over 11 thousand lines from the tree, always a nice thing, making up for the 12k lines added for the USB offload feature. - lots of little updates and fixes in different drivers All of these have been in linux-next for over 2 weeks, the USB offload logic has been in there for 8 weeks now, with no reported issues" * tag 'usb-6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (172 commits) ALSA: usb-audio: qcom: fix USB_XHCI dependency ASoC: qdsp6: fix compile-testing without CONFIG_OF usb: misc: onboard_usb_dev: fix build warning for CONFIG_USB_ONBOARD_DEV_USB5744=n usb: typec: tipd: fix typo in TPS_STATUS_HIGH_VOLAGE_WARNING macro USB: typec: fix const issue in typec_match() USB: gadget: udc: fix const issue in gadget_match_driver() USB: gadget: fix up const issue with struct usb_function_instance USB: serial: pl2303: add new chip PL2303GC-Q20 and PL2303GT-2AB USB: serial: bus: fix const issue in usb_serial_device_match() usb: usbtmc: Fix timeout value in get_stb usb: usbtmc: Fix read_stb function and get_stb ioctl ALSA: qc_audio_offload: try to reduce address space confusion ALSA: qc_audio_offload: avoid leaking xfer_buf allocation ALSA: qc_audio_offload: rename dma/iova/va/cpu/phys variables ALSA: usb-audio: qcom: Fix an error handling path in qc_usb_audio_probe() usb: misc: onboard_usb_dev: Fix usb5744 initialization sequence dt-bindings: usb: ti,usb8041: Add binding for TI USB8044 hub controller usb: misc: onboard_usb_dev: Add support for TI TUSB8044 hub usb: gadget: lpc32xx_udc: Use USB API functions rather than constants usb: gadget: epautoconf: Use USB API functions rather than constants ...
