Commit 6f4429e21a7f ("soc/tegra: pmc: Update address mapping sequence for PMC apertures") updated the resource lookup code in the PMC driver. Instead of calling platform_get_resource_byname() and devm_ioremap_resource() simplify the code by simply calling devm_platform_ioremap_resource_byname().

2024-06-26soc: samsung: exynos-pmu: update to use of_syscon_register_regmap()Peter Griffin
For SoCs like gs101 that need a special regmap, register this with of_syscon_register_regmap api, so it can be returned by syscon_regmap_lookup_by_phandle() and friends. For SoCs that don't require a custom regmap, revert back to syscon creating the mmio regmap rather than duplicating the logic here. exynos_get_pmu_regmap_by_phandle() api is also updated to retrieve the regmap via syscon. The exynos_get_pmu_regmap_by_phandle() api is kept around until fw_devlink support for syscon property is added for the pinctrl-samsung driver that also runs at postcore_initcall level. All other exynos client drivers can revert back to syscon_regmap_lookup_by_phandle().

2024-06-25soc: qcom: icc-bwmon: Allow for interrupts to be shared across instancesSibi Sankar
The multiple BWMONv4 instances available on the X1E80100 SoC use the same interrupt number. Mark them are shared to allow for re-use across instances. Using IRQF_SHARED coupled with devm_request_threaded_irq implies that the irq can still trigger during/after bwmon_remove due to other active bwmon instances. Handle this race by relying on bwmon_disable to disable the interrupt and coupled with explicit request/free irqs.

2024-06-25dim: make DIMLIB dependent on NETHeng Qi
DIMLIB's capabilities are supplied by the dim, net_dim, and rdma_dim objects, and dim's interfaces solely act as a base for net_dim and rdma_dim and are not explicitly used anywhere else. rdma_dim is utilized by the infiniband driver, while net_dim is for network devices, excluding the soc/fsl driver. In this patch, net_dim relies on some NET's interfaces, thus DIMLIB needs to explicitly depend on the NET Kconfig. The soc/fsl driver uses the functions provided by net_dim, so it also needs to depend on NET.

2024-06-24soc: qcom: add pd-mapper implementationDmitry Baryshkov
Existing userspace protection domain mapper implementation has several issue. It doesn't play well with CONFIG_EXTRA_FIRMWARE, it doesn't reread JSON files if firmware location is changed (or if firmware was not available at the time pd-mapper was started but the corresponding directory is mounted later), etc. Provide in-kernel service implementing protection domain mapping required to work with several services, which are provided by the DSP firmware. This module is loaded automatically by the remoteproc drivers when necessary via the symbol dependency. It uses a root node to match a protection domains map for a particular board. It is not possible to implement it as a 'driver' as there is no corresponding device.

2024-05-27soc: qcom: rpmh-rsc: Ensure irqs aren't disabled by rpmh_rsc_send_data() callersStephen Boyd
Dan pointed out that Smatch is concerned about this code because it uses spin_lock_irqsave() and then calls wait_event_lock_irq() which enables irqs before going to sleep. The comment above the function says it should be called with interrupts enabled, but we simply hope that's true without really confirming that. Let's add a might_sleep() here to confirm that interrupts and preemption aren't disabled. Once we do that, we can change the lock to be non-saving, spin_lock_irq(), to clarify that we don't expect irqs to be disabled. If irqs are disabled by callers they're going to be enabled anyway in the wait_event_lock_irq() call which would be bad. This should make Smatch happier and find bad callers faster with the might_sleep(). We can drop the WARN_ON() in the caller because we have the might_sleep() now, simplifying the code.

2024-05-22tracing/treewide: Remove second parameter of __assign_str()Steven Rostedt (Google)
With the rework of how the __string() handles dynamic strings where it saves off the source string in field in the helper structure[1], the assignment of that value to the trace event field is stored in the helper value and does not need to be passed in again. This means that with: __string(field, mystring) Which use to be assigned with __assign_str(field, mystring), no longer needs the second parameter and it is unused. With this, __assign_str() will now only get a single parameter. There's over 700 users of __assign_str() and because coccinelle does not handle the TRACE_EVENT() macro I ended up using the following sed script: git grep -l __assign_str | while read a ; do sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file; mv /tmp/test-file $a; done I then searched for __assign_str() that did not end with ';' as those were multi line assignments that the sed script above would fail to catch. Note, the same updates will need to be done for: __assign_str_len() __assign_rel_str() __assign_rel_str_len() I tested this with both an allmodconfig and an allyesconfig (build only for both).

https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers Qualcomm driver updates for v6.10 The Qualcomm SCM driver initialization order is improved, to avoid any potential for a client to find a half-initialized SCM instance. The handling of download mode bits is updated to not attempt QCOM_SCM_BOOT_SET_DLOAD_MODE if a io-address for the update is specified, and that path is changed to perform a read-modify-write to avoid updating unrelated bits. Error handling is corrected in the peripheral authentication service (PAS) functions, to release interconnect bandwidth votes in the case of an error. An unwanted error print on allocation error is also removed from this code path. The QSEECOM allow list is marked __maybe_unused to avoid build warnings when built with !OF. The error handling related to the interconnect API is cleaned up to avoid handling the impossible IS_ERR() condition. initcall level is bumped to "core" for cmd-db and rpmh-rsc, as dependent drivers like regulators, interconnects and clocks are registered at this level. Another attempt is made to remove the strncpy() usage in cmd-db, this time with strtomem_pad() which has the correct characteristics. The bwmon regmap cache is changed to maple tree. After an attempt to add missing MODULE_DEVICE_TABLEs to debug drivers, the intention of not having them automatically load is documented. Operations on the pmic_glink client list is put under mutual exclusion, to avoid races when clients are being registered. pmic_glink client registered after the firmware notification arrived was not informed that the firmware was up, this is resolved. More DSPs and the apss subsystem is added to the Qualcomm sleep stats driver. Checks for in-flight regulator requests in the RPMh RSC driver is improved to deal with the fact that these occupy multiple registers, so it's insufficient to just to direct address comparison. The socinfo drivers learns about X1 Elite and SMB2360 PMIC. The maintainers entry is split between the linux-arm-msm list and subset that is maintained in the qcom-soc tree, to avoid some confusion about maintainership. * tag 'qcom-drivers-for-6.10' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (21 commits) soc: qcom: cmd-db: replace deprecated strncpy with strtomem soc: qcom: rpmh-rsc: Enhance check for VRM in-flight request firmware: qcom: scm: Modify only the download bits in TCSR register firmware: qcom: scm: Fix __scm and waitq completion variable initialization firmware: qcom: scm: Rework dload mode availability check firmware: qcom: scm: Remove redundant scm argument from qcom_scm_waitq_wakeup() firmware: qcom: scm: Remove log reporting memory allocation failure soc: qcom: pmic_glink: notify clients about the current state soc: qcom: pmic_glink: don't traverse clients list without a lock soc: qcom: mention intentionally broken module autoloading firmware: qcom: qcm: fix unused qcom_scm_qseecom_allowlist MAINTAINERS: Split Qualcomm SoC and linux-arm-msm entries soc: qcom: qcom_stats: Add DSPs and apss subsystem stats dt-bindings: soc: qcom: qcom,pmic-glink: document QCM6490 compatible soc: qcom: socinfo: Add SMB2360 PMIC soc: qcom: socinfo: Add X1E80100 SoC ID table entry dt-bindings: arm: qcom,ids: Add SoC ID for X1E80100 soc: qcom: Update init level to core_initcall() for cmd-db and rpmh-rsc soc: qcom: icc-bwmon: Convert to use maple tree register cache firmware: qcom_scm: remove IS_ERR() checks from qcom_scm_bw_{en,dis}able() ...
