Sat, 25 Apr 2026 14:54:29 +0200

misc: Remove old APDS990x driverThe APDS990x driver in misc lacks DeviceTree support, and no mainlinepre-DT board files configured this device using apds990x_platform_data.This driver belongs to a legacy group of ambient light sensor drivers indrivers/misc/ that predates the migration to DT and the standard IIO ABI.Since the Avago APDS9900/9901 ALS/Proximity sensor is now supported bythe tsl2772 IIO driver and there are no active users in the kernel tree,remove this old implementation.Acked-by: Greg Kroah-Hartman Signed-off-by: Svyatoslav Ryhel Signed-off-by: Jonathan Cameron List of files: /linux/drivers/misc/Makefile

Thu, 29 May 2025 15:50:44 +0200

misc: rp1: RaspberryPi RP1 misc driverThe RaspberryPi RP1 is a PCI multi function device containingperipherals ranging from Ethernet to USB controller, I2C, SPIand others.Implement a bare minimum driver to operate the RP1, leveragingactual OF based driver implementations for the on-board peripheralsby loading a devicetree overlay during driver probe if the RP1node is not already present in the DT.The peripherals are accessed by mapping MMIO registers startingfrom PCI BAR1 region.With the overlay approach we can achieve more generic and agnosticapproach to managing this chipset, being that it is a PCI endpointand could possibly be reused in other hw implementations. Thepresented approach is also used by Bootlin's Microchip LAN966xpatchset (see link) as well, for a similar chipset.In this case, the inclusion tree for the DT overlay is as follow(the arrow points to the includer): rp1-pci.dtso <---- rp1-common.dtsiOn the other hand, to ensure compatibility with downstream, thisdriver can also work with a DT already comprising the RP1 node, sothe dynamically loaded overlay will not be used if the DT is alreadyfully defined.The reason why this driver is contained in drivers/misc hasbeen paved by Bootlin's LAN966X driver, which first used theoverlay approach to implement non discoverable peripherals behind aPCI bus. For RP1, the same arguments apply: it's not used as an SoCsince the driver code is not running on-chip and is not like an MFDsince it does not really need all the MFD infrastructure (shared regs,etc.). So, for this particular use, misc has been proposed and deemedas a good choice. For further details about that please check the links.This driver is heavily based on downstream code from RaspberryPiFoundation, and the original author is Phil Elwell.Link: https://datasheets.raspberrypi.com/rp1/rp1-peripherals.pdfLink: https://lore.kernel.org/all/20240612140208.GC1504919@google.com/Link: https://lore.kernel.org/all/83f7fa09-d0e6-4f36-a27d-cee08979be2a@app.fastmail.com/Link: https://lore.kernel.org/all/2024081356-mutable-everyday-6f9d@gregkh/Link: https://lore.kernel.org/all/20240808154658.247873-1-herve.codina@bootlin.com/Signed-off-by: Andrea della Porta Acked-by: Bjorn Helgaas # quirks.c, pci_ids.hAcked-by: Greg Kroah-Hartman Link: https://lore.kernel.org/r/20250529135052.28398-7-andrea.porta@suse.comSigned-off-by: Florian Fainelli List of files: /linux/drivers/misc/Makefile

So even in the few cases where it is packagedand built, the kernel copy isn't used.Signed-off-by: "Dr. David Alan Gilbert" Link: https://lore.kernel.org/r/20250427224022.113678-1-linux@treblig.orgSigned-off-by: Greg Kroah-Hartman List of files: /linux/drivers/misc/Makefile

rpmb: add Replay Protected Memory Block (RPMB) subsystemA number of storage technologies support a specialised hardwarepartition designed to be resistant to replay attacks. The underlyingHW protocols differ but the operations are common. The RPMB partitioncannot be accessed via standard block layer, but by a set of specificRPMB commands. Such a partition provides authenticated and replayprotected access, hence suitable as a secure storage.The initial aim of this patch is to provide a simple RPMB driverinterface which can be accessed by the optee driver to facilitate earlyRPMB access to OP-TEE OS (secure OS) during the boot time.A TEE device driver can claim the RPMB interface, for example, viarpmb_interface_register() or rpmb_dev_find_device(). The RPMB driverprovides a callback to route RPMB frames to the RPMB device accessiblevia rpmb_route_frames().The detailed operation of implementing the access is left to the TEEdevice driver itself.Signed-off-by: Tomas Winkler Signed-off-by: Alex Bennée Signed-off-by: Shyam Saini Signed-off-by: Jens Wiklander Reviewed-by: Linus Walleij Tested-by: Manuel Traut Reviewed-by: Ulf Hansson Reviewed-by: Greg Kroah-Hartman Link: https://lore.kernel.org/r/20240814153558.708365-2-jens.wiklander@linaro.orgSigned-off-by: Ulf Hansson List of files: /linux/drivers/misc/Makefile
