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 ...

soc: microchip: add mpfs gpio interrupt mux driver

2026-03-31T13:13:14+00:00

On PolarFire SoC there are more GPIO interrupts than there are interrupt lines available on the PLIC, and a runtime configurable mux is used to decide which interrupts are assigned direct connections to the PLIC & which are relegated to sharing a line. Add a driver so that Linux can set the mux based on the interrupt mapping in the devicetree.

soc: microchip: mpfs-sys-controller: add support for pic64gx

2026-03-03T17:08:41+00:00

pic64gx is not compatible with mpfs because due to the lack of FPGA functionality some features are disabled. Notably, anything to do with FPGA fabric contents is not supported. Signed-off-by: Pierre-Henry Moussay Signed-off-by: Conor Dooley

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

soc: microchip: mpfs: Fix memory leak in mpfs_sys_controller_probe()

2026-01-15T19:15:19+00:00

In mpfs_sys_controller_probe(), if of_get_mtd_device_by_node() fails, the function returns immediately without freeing the allocated memory for sys_controller, leading to a memory leak. Fix this by jumping to the out_free label to ensure the memory is properly freed. Also, consolidate the error handling for the mbox_request_channel() failure case to use the same label.
