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 ...

+Description:
+ These interfaces under /sys/devices/platform/HISI04Bx/ are
+ used to support the low power consumption feature of some
+ HCCS types by changing the number of lanes used. The interfaces
+ changing the number of lanes used are 'dec_lane_of_type' and
+ 'inc_lane_of_type' which require root privileges. These
+ interfaces aren't exposed if no HCCS type on platform support
+ this feature. Please note that decreasing lane number is only
+ allowed if all the specified HCCS ports are not busy.
+
+ The low power consumption interfaces are as follows:
+
+ ============================= ==== ================================
+ available_inc_dec_lane_types: (RO) available HCCS types (string) to
+ increase and decrease the number
+ of lane used, e.g. HCCS-v2.
+ dec_lane_of_type: (WO) input HCCS type supported
+ decreasing lane to decrease the
+ used lane number of all specified
+ HCCS type ports on platform to
+ the minimum.
+ You can query the 'cur_lane_num'
+ to get the minimum lane number
+ after executing successfully.
+ inc_lane_of_type: (WO) input HCCS type supported
+ increasing lane to increase the
+ used lane number of all specified
+ HCCS type ports on platform to
+ the full lane state.

+title: MediaTek Dynamic Voltage and Frequency Scaling Resource Collector (DVFSRC)
+
+description:
+ The Dynamic Voltage and Frequency Scaling Resource Collector (DVFSRC) is a
+ Hardware module used to collect all the requests from both software and the
+ various remote processors embedded into the SoC and decide about a minimum
+ operating voltage and a minimum DRAM frequency to fulfill those requests in
+ an effort to provide the best achievable performance per watt.
+ This hardware IP is capable of transparently performing direct register R/W
+ on all of the DVFSRC-controlled regulators and SoC bandwidth knobs.
