2025-05-13soc: samsung: exynos-pmu: enable CPU hotplug support for gs101Peter Griffin
Some additional register writes are required when hotplugging CPUs on gs101, without these the system hangs when hotplugging. Specifically a CPU_INFORM register needs to be programmed with a hint value which is used by the EL3 firmware (el3mon) and the pmu-intr-gen registers need to be programmed. With this patch applied, and corresponding DT update CPU hotplug now works as expected. e.g. echo 0 > /sys/devices/system/cpu/cpu6/online echo 1 > /sys/devices/system/cpu/cpu6/online Note: to maintain compatibility with older DTs that didn't specify pmu-intr-gen phandle only a warning is issued if the syscon can't be obtained.

2025-05-13bus: fsl-mc: Use strscpy() instead of strscpy_pad()Thorsten Blum
Both destination buffers are already zero-initialized, making strscpy() sufficient for safely copying 'obj_type'. The additional NUL-padding performed by strscpy_pad() is unnecessary. If the destination buffer has a fixed length, strscpy() automatically determines its size using sizeof() when the argument is omitted. This makes the explicit size arguments unnecessary. No functional changes intended.

2025-05-13soc: fsl: qbman: Remove const from portal->cgrs allocation typeKees Cook
In preparation for making the kmalloc family of allocators type aware, we need to make sure that the returned type from the allocation matches the type of the variable being assigned. (Before, the allocator would always return "void *", which can be implicitly cast to any pointer type.) The assigned type is "struct qman_cgrs *", but the returned type, while technically matching, is const qualified. As there is no general way to remove const qualifiers, adjust the allocation type to match the assignment.

2025-05-13bus: fsl_mc: Fix driver_managed_dma checkRobin Murphy
Since it's not currently safe to take device_lock() in the IOMMU probe path, that can race against really_probe() setting dev->driver before attempting to bind. The race itself isn't so bad, since we're only concerned with dereferencing dev->driver itself anyway, but sadly my attempt to implement the check with minimal churn leads to a kind of TOCTOU issue, where dev->driver becomes valid after to_fsl_mc_driver(NULL) is already computed, and thus the check fails to work as intended. Will and I both hit this with the platform bus, but the pattern here is the same, so fix it for correctness too.

2025-05-13bus: fsl-mc: do not add a device-link for the UAPI used DPMCP deviceIoana Ciornei
The fsl-mc bus associated to the root DPRC in a DPAA2 system exports a device file for userspace access to the MC firmware. In case the DPRC's local MC portal (DPMCP) is currently in use, a new DPMCP device is allocated through the fsl_mc_portal_allocate() function. In this case, the call to fsl_mc_portal_allocate() will fail with -EINVAL when trying to add a device link between the root DPRC (consumer) and the newly allocated DPMCP device (supplier). This is because the DPMCP is a dependent of the DPRC device (the bus). Fix this by not adding a device link in case the DPMCP is allocated for the root DPRC's usage.

2025-05-13bus: fsl-mc: fix double-free on mc_devIoana Ciornei
The blamed commit tried to simplify how the deallocations are done but, in the process, introduced a double-free on the mc_dev variable. In case the MC device is a DPRC, a new mc_bus is allocated and the mc_dev variable is just a reference to one of its fields. In this circumstance, on the error path only the mc_bus should be freed. This commit introduces back the following checkpatch warning which is a false-positive. WARNING: kfree(NULL) is safe and this check is probably not required + if (mc_bus) + kfree(mc_bus); Fixes: a042fbed0290 ("staging: fsl-mc: simplify couple of deallocations") Signed-off-by: Ioana Ciornei <ioana.ciornei@nxp.com> Link: https://lore.kernel.org/r/20250408105814.2837951-2-ioana.ciornei@nxp.com Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu>

When the binding was originally written, it was assumed that all ax45mp-caches had the same properties etc. This has turned out to be incorrect, as the QiLai SoC has a different number of cache-sets. Add a specific compatible for the RZ/Five for property enforcement and in case there turns out to be additional differences between these implementations of the cache controller.
