This refinement would pass struct cmdq_pkt pointer into cmdq_pkt_create(). In addition, client driver has the struct cmdq_client information, so it's not necessary to store this information in struct cmdq_pkt. After this refinement, client drivers could use these helper funciton instead of implementing its own version.

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() ...

We should prefer more robust and less ambiguous alternatives. @query is marked as __nonstring and doesn't need to be NUL-terminated. Since we are doing a string to memory copy, we can use the aptly named "strtomem" -- specifically, the "pad" variant to also ensure NUL-padding throughout the destination buffer.

These control voltage, enable state, mode, and in legacy targets, voltage headroom. The current in-flight request checking logic looks for exact address matches. Requests for different addresses of the same RPMh resource as thus not detected as in-flight. Add new cmd-db API cmd_db_match_resource_addr() to enhance the in-flight request check for VRM requests by ignoring the address offset. This ensures that only one request is allowed to be in-flight for a given VRM resource. This is needed to avoid scenarios where request commands are carried out by RPMh hardware out-of-order leading to LDO regulator over-current protection triggering.

If bit 16 is set (the reset value), the temperature readings of the THS are way off, leading to reports about 200C, at normal ambient temperatures. Clearing this bits brings the reported values down to the expected values. The BSP code clears this bit in firmware (U-Boot), and has an explicit comment about this, but offers no real explanation. Experiments in U-Boot show that register 0x0 has no effect on the SRAM C visibility: all tested bit settings still allow full read and write access by the CPU to the whole of SRAM C. Only bit 24 of the register at offset 0x4 makes all of SRAM C inaccessible by the CPU. So modelling the THS switch functionality as an SRAM region would not reflect reality. Since we should not rely on firmware settings, allow other code (the THS driver) to access this register, by exporting it through the already existing regmap. This mimics what we already do for the LDO control and the EMAC register. To avoid concurrent accesses to the same register at the same time, by the SRAM switch code and the regmap code, use the same lock to protect the access. The regmap subsystem allows to use an existing lock, so we just need to hook in there.

Extend Exynos PMU (Power Management Unit) driver being also the syscon to main system controller registers block, to support Google GS101. The Google GS101 has PMU registers protected and writing is available only via SMC. The Exynos PMU will register its own custom regmap for such case of mixed MMIO+SMC. 2. Rework Samsung watchdog driver to get the regmap to PMU block not via syscon API, but from the Exynos PMU driver. This is necessary for the watchdog driver to work on Google GS101. * tag 'samsung-drivers-6.9-2' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux: watchdog: s3c2410_wdt: use exynos_get_pmu_regmap_by_phandle() for PMU regs soc: samsung: exynos-pmu: Add regmap support for SoCs that protect PMU regs MAINTAINERS: samsung: gs101: match patches touching Google Tensor SoC Link: https://lore.kernel.org/r/20240227080755.34170-1-krzysztof.kozlowski@linaro.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>

As most Exynos drivers that need to write PMU registers currently obtain a regmap via syscon (phys, pinctrl, watchdog). Support for the above usecase is implemented in this driver using a custom regmap similar to syscon to handle the SMC call. Platforms that don't secure PMU registers, get a mmio regmap like before. As regmaps abstract out the underlying register access changes to the leaf drivers are minimal. A new API exynos_get_pmu_regmap_by_phandle() is provided for leaf drivers that currently use syscon_regmap_lookup_by_phandle(). This also handles deferred probing.

The Qualcomm SMEM no longer acquires the hwspinlock during the "get" operation, to improve the system behavior during the recovery of a remoteproc that crashed with the hwspinlock held. The Qualcomm Always On Subsystem (AOSS) message protocol driver gains tracepoints, printf annotation, and a debugfs interface is introduced for tweaking system properties during development and debugging. The Qualcomm socinfo driver gains data for SM8475, QCM8550 and QCS8550 platforms, and the PM2250 is renamed to PM4125. Support for controlling the voltage regulator in SPM/SAW2 is introduced. The gfx.lvl power-domain is dropped for SA8540P, as this resource was incorrectly inherited from SC8280XP.
