Pull SoC driver updates from Arnd Bergmann: "The SoC driver changes once more consist of many small fixes and cleanups, that are to a large part the result of automated testing. On platform specific drivers, this includes SoC specific code for xilinx, freescale/nxp, qualcomm, TI, aspeed, omap, tegra, samsung, rockchip, renesas, ixp4xx. In firmware drivers, we see a similar picture for SCMI and qcomtee. Aside from these, we see actual new hardware support in a few areas: - The Apple platform gets a new driver for low power states - Updates to Qualcomm platform drivers add several new hardware specific features and additional SoCs. - Amlogic SoC support for A1 and T7 is added - The Mediatek MMSYS driver is refactored as a cleanup" * tag 'soc-drivers-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (157 commits) soc: qcom: make QCOM_PDR_MSG selectable soc: qcom: ubwc: Fix missing include soc: qcom: ubwc: Fix link error when QCOM_SMEM=n media: iris: Guard the QCOM_UBWC_CONFIG select with QCOM_SMEM drm/msm: Guard the QCOM_UBWC_CONFIG select with QCOM_SMEM dt-bindings: arm: qcom,ids: Add SoC ID for Snapdragon SDM 850 firmware: xilinx: Clear firmware notifiers across kexec transitions firmware: xilinx: Release all peripheral devices from firmware firmware: xilinx: Add support to clear EL3 PM state firmware: xilinx: Propagate actual error from feature check firmware: xilinx: Use TF-A feature check for TF-A-specific APIs bus: fsl-mc: drop unused assignment of acpi_device_id::driver_data soc: fsl: qe: check platform_driver_register() in qe_ic_of_init() phy: lynx-10g: use RCW override procedure for dynamic protocol change soc: fsl: guts: implement the RCW override procedure dt-bindings: fsl: layerscape-dcfg: define DCFG_DCSR region soc: fsl: guts: make fsl_soc_data available after fsl_guts_init() soc: fsl: guts: make it easier to determine on which SoC we are running soc: fsl: guts: add a central fsl_guts_read() function soc: fsl: guts: add a global structure to hold state ...

soc/tegra: Add PM dependency to SOC_TEGRA_PMC Kconfig

2026-07-31T15:56:37+00:00

kconfiglint reports: K006: config SOC_TEGRA_PMC selects PM_GENERIC_DOMAINS which depends on PM, but SOC_TEGRA_PMC does not depend on PM SOC_TEGRA_PMC is an internal bool symbol (no prompt) that is selected by ARCH_TEGRA_*_SOC options to enable the Power Management Controller driver. It was originally introduced in commit 5e7d4c652941 ("soc/tegra: Implement Tegra186 PMC support") as a bare `bool` with no selects of its own. Over time, additional selects were added: - Commit 5098e2b95e8e ("soc/tegra: pmc: Select GENERIC_PINCONF") added select GENERIC_PINCONF - Commit 28dbe8231066 ("soc/tegra: pmc: Select IRQ_DOMAIN_HIERARCHY") added select IRQ_DOMAIN_HIERARCHY - Commit f880ee9e9688 ("soc/tegra: pmc: Add core power domain") added select PM_OPP and select PM_GENERIC_DOMAINS to support core power domain voltage scaling PM_GENERIC_DOMAINS is defined in kernel/power/Kconfig as: config PM_GENERIC_DOMAINS bool depends on PM When commit f880ee9e9688 ("soc/tegra: pmc: Add core power domain") added the select, it did not add a corresponding `depends on PM` to SOC_TEGRA_PMC. This was not a functional problem because all callers of SOC_TEGRA_PMC are inside `if ARCH_TEGRA` blocks, and both the ARM32 definition (arch/arm/mach-tegra/Kconfig) and the ARM64 definition (arch/arm64/Kconfig.platforms) of ARCH_TEGRA select PM. Thus PM is always enabled when SOC_TEGRA_PMC is selected in practice. However, the dependency chain is implicit rather than explicit. Add `depends on PM` to SOC_TEGRA_PMC to make the requirement explicit and prevent a theoretical misconfiguration if SOC_TEGRA_PMC were ever selected outside the ARCH_TEGRA context.

soc/tegra: fuse: Use device-specific instance in suspend/resume

2026-07-31T15:46:41+00:00

Avoid using the default fuse instance in suspend/resume callbacks, as it always runs the suspend/resume callbacks for the default instance rather than the device’s own. Get the correct fuse instance by using `dev_get_drvdata()`. Signed-off-by: Kartik Rajput Signed-off-by: Thierry Reding

soc/tegra: fuse: Do not use fuse data as entropy source

2026-07-31T15:43:30+00:00

Fuse values are static and device-unique but not secret. Using them as an entropy source weakens the overall randomness pool because the data is constant and externally observable over the device’s lifetime. Stop feeding fuse data into the kernel’s randomness subsystem. Signed-off-by: Kartik Rajput Signed-off-by: Thierry Reding

soc/tegra: cbb: Remove redundant dev_err()

2026-07-31T15:33:33+00:00

Since commit 55b48e23f5c4 ("genirq/devres: Add error handling in devm_request_*_irq()"), devm_request_irq() automatically logs detailed error messages on failure. Remove the now-redundant driver-specific dev_err() calls. Signed-off-by: Pan Chuang Reviewed-by: Mikko Perttunen Signed-off-by: Thierry Reding

soc/tegra: pmc: Don't register sys-off handler for multi-socket devices

2026-07-15T11:39:42+00:00

The kernel does not permit a device to register multiple sys-off handlers for non-default priority levels. Hence, for multi-socket Tegra devices, registering the sys-off handler in the Tegra PMC driver (which uses the low priority level) more than once fails. The Tegra PMC sys-off handler is supported for all current generations of the Tegra SoC, however, it is only used as a low priority handler if everything else fails. For example, on Tegra264 the EFI reboot handler is called to restart the device. Therefore, for multi-socket devices, skip the registering of the sys-off handler to because this is not critical.

Replace by more specific (c files)

2026-07-03T05:38:17+00:00

Replace the #include of by the more specific where applicable. For most cases the include can be dropped completely, only a few drivers need one or two headers added.

soc/tegra: fuse: Fix spurious straps warning on SMCCC platforms

2026-06-22T07:25:36+00:00

My Grace host started to show this warning: WARNING: drivers/soc/tegra/fuse/tegra-apbmisc.c:120 at tegra_read_straps tegra30_fuse_add_randomness tegra30_fuse_init tegra_fuse_probe tegra_read_straps() warns when the static "chipid" cache is still zero, using it as a proxy for "APBMISC has been initialised". However chipid is only ever populated lazily by tegra_read_chipid() when it reads the APBMISC register. Guard on apbmisc_base instead, which is set unconditionally in tegra_init_apbmisc_resources() for all platforms and is already the sentinel used by tegra_read_chipid().
