Merge tag 'soc-drivers-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

2026-04-17T03:34:34Z

Pull SoC driver updates from Arnd Bergmann: "The driver updates again are all over the place with many minor fixes going into platform specific code. The most notable changes are: - Support for Microchip pic64gx system controllers - Work on cleaning up devicetree bindings for SoC drivers, and converting them into the new format - Lots of smaller changes for Qualcomm SoC drivers, including support for a number of newly supported chips - reset controller API cleanups and a new driver for Cix Sky1 - Reworks of the Tegra PMC and CBB drivers, along with a change to how individual Tegra SoCs get selected in Kconfig and BPMP firmware driver updates including a refresh of the ABI header to match the version used by firmware - STM32 updates to the firewall bus driver and support for the debug bus through OP-TEE - SCMI firmware driver improvements for reliability, in particular for dealing with broken firmware interrupts - Memory driver updates for Tegra, and a patch to remove the unused Baikal T1 driver" * tag 'soc-drivers-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (193 commits) firmware: arm_ffa: Use the correct buffer size during RXTX_MAP firmware: qcom: scm: Allow QSEECOM on Lenovo IdeaCentre Mini X clk: spear: fix resource leak in clk_register_vco_pll() reset: rzv2h-usb2phy: Add support for VBUS mux controller registration reset: rzv2h-usb2phy: Convert to regmap API dt-bindings: reset: renesas,rzv2h-usb2phy: Document RZ/G3E USB2PHY reset dt-bindings: reset: renesas,rzv2h-usb2phy: Add '#mux-state-cells' property soc: microchip: add mpfs gpio interrupt mux driver dt-bindings: soc: microchip: document PolarFire SoC's gpio interrupt mux gpio: mpfs: Add interrupt support soc: qcom: ubwc: add helpers to get programmable values soc: qcom: ubwc: add helper to get min_acc length firmware: qcom: scm: Register gunyah watchdog device soc: qcom: socinfo: Add SoC ID for SA8650P dt-bindings: arm: qcom,ids: Add SoC ID for SA8650P firmware: qcom: scm: Allow QSEECOM on Mahua CRD soc: qcom: wcnss: simplify allocation of req soc: qcom: pd-mapper: Add support for Eliza soc: qcom: aoss: compare against normalized cooling state soc: qcom: llcc: fix v1 SB syndrome register offset ...

gpio: Add Intel Nova Lake ACPI GPIO events driver

2026-04-07T10:32:21Z

This driver provides support for new way of handling platform events, through the use of GPIO-signaled ACPI events. This mechanism is used on Intel client platforms released in 2026 and later, starting with Intel Nova Lake.

gpio: mpfs: Add interrupt support

2026-03-31T13:13:14Z

Add support for interrupts to the PolarFire SoC GPIO driver. Each GPIO has an independent interrupt that is wired to an interrupt mux that sits between the controllers and the PLIC. The SoC has more GPIO lines than connections from the mux to the PLIC, so some GPIOs must share PLIC interrupts. The configuration is not static and is set at runtime, conventionally by the platform's firmware. CoreGPIO, the version intended for use in the FPGA fabric has two interrupt output ports, one is IO_NUM bits wide, as is used in the hardened cores, and the other is a single bit with all lines ORed together.
