Merge tag 'soc-drivers-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull SoC driver updates from Arnd Bergmann: "Nothing particular important in the SoC driver updates, just the usual improvements to for drivers/soc and a couple of subsystems that don't fit anywhere else: - The largest set of updates is for Qualcomm SoC drivers, extending the set of supported features for additional SoCs in the QSEECOM, LLCC and socinfo drivers.a - The ti_sci firmware driver gains support for power managment - The drivers/reset subsystem sees a rework of the microchip sparx5 and amlogic reset drivers to support additional chips, plus a few minor updates on other platforms - The SCMI firmware interface driver gains support for two protocol extensions, allowing more flexible use of the shared memory area and new DT binding properties for configurability. - Mediatek SoC drivers gain support for power managment on the MT8188 SoC and a new driver for DVFS. - The AMD/Xilinx ZynqMP SoC drivers gain support for system reboot and a few bugfixes - The Hisilicon Kunpeng HCCS driver gains support for configuring lanes through sysfs Finally, there are cleanups and minor fixes for drivers/{soc, bus, memory}, including changing back the .remove_new callback to .remove, as well as a few other updates for freescale (powerpc) soc drivers, NXP i.MX soc drivers, cznic turris platform driver, memory controller drviers, TI OMAP SoC drivers, and Tegra firmware drivers" * tag 'soc-drivers-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (116 commits) soc: fsl: cpm1: qmc: Set the ret error code on platform_get_irq() failure soc: fsl: rcpm: fix missing of_node_put() in copy_ippdexpcr1_setting() soc: fsl: cpm1: tsa: switch to for_each_available_child_of_node_scoped() platform: cznic: turris-omnia-mcu: Rename variable holding GPIO line names platform: cznic: turris-omnia-mcu: Document the driver private data structure firmware: turris-mox-rwtm: Document the driver private data structure bus: Switch back to struct platform_driver::remove() soc: qcom: ice: Remove the device_link field in qcom_ice drm/msm/adreno: Setup SMMU aparture for per-process page table firmware: qcom: scm: Introduce CP_SMMU_APERTURE_ID firmware: arm_scpi: Check the DVFS OPP count returned by the firmware soc: qcom: socinfo: add IPQ5424/IPQ5404 SoC ID dt-bindings: arm: qcom,ids: add SoC ID for IPQ5424/IPQ5404 soc: qcom: llcc: Flip the manual slice configuration condition dt-bindings: firmware: qcom,scm: Document sm8750 SCM firmware: qcom: uefisecapp: Allow X1E Devkit devices misc: lan966x_pci: Fix dtc warn 'Missing interrupt-parent' misc: lan966x_pci: Fix dtc warns 'missing or empty reg/ranges property' soc: qcom: llcc: Add LLCC configuration for the QCS8300 platform dt-bindings: cache: qcom,llcc: Document the QCS8300 LLCC ...
