Merge tag 'soc-arm-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

2026-06-17T18:28:10+00:00

Pull arm SoC code updates from Arnd Bergmann: "The largest addition here is the revived support for the ZTE ZX SoC platform, though this mostly documentation. The other changes are code cleanups that deal with continued conversion of the GPIO library away from GPIO numbers to descriptors and a few minor bugfixes" * tag 'soc-arm-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: MAINTAINERS: Add Axiado reviewer and Maintainers ARM: remove the last few uses of do_bad_IRQ() ARM: imx31: Fix IIM mapping leak in revision check ARM: imx3: Fix CCM node reference leak ARM: orion5x: update board check in mss2_pci_init() to use the DT arm: mvebu_v5_defconfig: remove stale MACH_LINKSTATION_LSCHL reference ARM: mvebu: simplify of_node_put calls ARM: mvebu: drop unnecessary NULL check arm: boot: ep93xx: don't rely on machine_is_*() for removed board files ARM: zte: clean up zx297520v3 doc. warnings arm64: Kconfig: drop unneeded dependency on OF_GPIO for ARCH_MVEBU firmware: imx: sm-misc: Make scmi_imx_misc_ctrl_nb variable static ARM: zte: Add zx297520v3 platform support ARM: pxa: pxa27x: attach software node to its target GPIO controller ARM: pxa: pxa25x: attach software node to its target GPIO controller ARM: pxa: spitz: attach software nodes to their target GPIO controllers ARM: pxa: statify platform device definitions in spitz board file ARM: omap2: simplify allocation for omap_device ARM: select legacy gpiolib interfaces where used ARM: s3c: use gpio lookup table for LEDs

firmware: imx: sm-misc: Make scmi_imx_misc_ctrl_nb variable static

2026-05-19T15:58:09+00:00

File-scope 'scmi_imx_misc_ctrl_nb' is not used outside of this unit, so make it static to silence sparse warning: sm-misc.c:19:23: warning: symbol 'scmi_imx_misc_ctrl_nb' was not declared. Should it be static? Reviewed-by: Daniel Baluta Signed-off-by: Krzysztof Kozlowski Signed-off-by: Frank Li

firmware: imx: sm-misc: Print boot/shutdown reasons

2026-05-05T14:45:53+00:00

Add reset reason string table for i.MX95 and introduce a helper (scmi_imx_misc_get_reason) to query and print both system and LM (Logical Machine) reset reasons via the SCMI MISC protocol.

firmware: imx: scu: Use devm_mutex_init

2025-10-27T06:43:48+00:00

In normal case, there is no need to invoke mutex_destroy in error path, but it is useful when CONFIG_DEBUG_MUTEXES, so use devm_mutex_init(). Reviewed-by: Frank Li Signed-off-by: Peng Fan Signed-off-by: Shawn Guo

firmware: imx: scu: Suppress bind attrs

2025-10-27T06:43:47+00:00

The SCU driver is critical for system working properly, it should never be removed and binded again. So suppress the bind attrs Reviewed-by: Frank Li Signed-off-by: Peng Fan Signed-off-by: Shawn Guo

firmware: imx: scu: Update error code

2025-10-27T06:43:47+00:00

IMX_SC_ERR_NOTFOUND should map with -ENOENT, not -EEXIST. -ENODEV makes more sense for IMX_SC_ERR_NOPOWER, and -ECOMM makes more sense for IMX_SC_ERR_IPC. Reviewed-by: Frank Li Signed-off-by: Peng Fan Signed-off-by: Shawn Guo

firmware: imx: scu-irq: Remove unused export of imx_scu_enable_general_irq_channel

2025-10-27T06:43:47+00:00

Since its introduction, this symbol has not been used by any loadable modules. It remains only referenced within imx-scu.c, which is always built together with imx-scu-irq.c As such, exporting imx_scu_enable_general_irq_channel is unnecessary, so remove the export.

firmware: imx: scu-irq: Set mu_resource_id before get handle

2025-10-27T06:43:47+00:00

mu_resource_id is referenced in imx_scu_irq_get_status() and imx_scu_irq_group_enable() which could be used by other modules, so need to set correct value before using imx_sc_irq_ipc_handle in SCU API call. Reviewed-by: Frank Li Signed-off-by: Peng Fan Signed-off-by: Shawn Guo

firmware: imx: scu-irq: Init workqueue before request mbox channel

2025-10-27T06:43:47+00:00

With mailbox channel requested, there is possibility that interrupts may come in, so need to make sure the workqueue is initialized before the queue is scheduled by mailbox rx callback. Reviewed-by: Frank Li Signed-off-by: Peng Fan Signed-off-by: Shawn Guo
