Merge tag 'soc-drivers-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/socPull SoC driver updates from Arnd Bergmann: "The driver updates again are all over the place with many minor fixes going into platform specific code. The most notable changes are: - Support for Microchip pic64gx system controllers - Work on cleaning up devicetree bindings for SoC drivers, and converting them into the new format - Lots of smaller changes for Qualcomm SoC drivers, including support for a number of newly supported chips - reset controller API cleanups and a new driver for Cix Sky1 - Reworks of the Tegra PMC and CBB drivers, along with a change to how individual Tegra SoCs get selected in Kconfig and BPMP firmware driver updates including a refresh of the ABI header to match the version used by firmware - STM32 updates to the firewall bus driver and support for the debug bus through OP-TEE - SCMI firmware driver improvements for reliability, in particular for dealing with broken firmware interrupts - Memory driver updates for Tegra, and a patch to remove the unused Baikal T1 driver"* tag 'soc-drivers-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (193 commits) firmware: arm_ffa: Use the correct buffer size during RXTX_MAP firmware: qcom: scm: Allow QSEECOM on Lenovo IdeaCentre Mini X clk: spear: fix resource leak in clk_register_vco_pll() reset: rzv2h-usb2phy: Add support for VBUS mux controller registration reset: rzv2h-usb2phy: Convert to regmap API dt-bindings: reset: renesas,rzv2h-usb2phy: Document RZ/G3E USB2PHY reset dt-bindings: reset: renesas,rzv2h-usb2phy: Add '#mux-state-cells' property soc: microchip: add mpfs gpio interrupt mux driver dt-bindings: soc: microchip: document PolarFire SoC's gpio interrupt mux gpio: mpfs: Add interrupt support soc: qcom: ubwc: add helpers to get programmable values soc: qcom: ubwc: add helper to get min_acc length firmware: qcom: scm: Register gunyah watchdog device soc: qcom: socinfo: Add SoC ID for SA8650P dt-bindings: arm: qcom,ids: Add SoC ID for SA8650P firmware: qcom: scm: Allow QSEECOM on Mahua CRD soc: qcom: wcnss: simplify allocation of req soc: qcom: pd-mapper: Add support for Eliza soc: qcom: aoss: compare against normalized cooling state soc: qcom: llcc: fix v1 SB syndrome register offset ...

Merge tag 'stm32-bus-firewall-for-7.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/atorgue/stm32 into soc/driversSTM32 Firewall bus for v7.1, round 1Highlights:----------Stm32 SoCs embed debug peripherals such as Coresight. These peripheralscan monitor the activity of the cores. Because of that, they can beused only if some features in the debug configuration are enabled.Else, errors or firewall exceptions can be observed. Similarly tothe ETZPC(on stm32mp1x platforms) or the RIFSC(on stm32mp2x platforms),debug-related peripherals access can be assessed at bus level toprevent these issues from happening.The debug configuration can only be accessed by the secure world.That means that a service must be implemented in the secure world forthe kernel to check the firewall configuration. On OpenSTLinux, it isdone through a Debug access PTA in OP-TEE [1].To represent the debug peripherals present on a dedicated debug bus,create a debug bus node in the device tree and the associated driverthat will interact with this PTA.Plus some fixes.* tag 'stm32-bus-firewall-for-7.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/atorgue/stm32: pinctrl: stm32: add firewall checks before probing the HDP driver drivers: bus: add the stm32 debug bus driver bus: stm32_firewall: add stm32_firewall_get_grant_all_access() API bus: stm32_firewall: allow check on different firewall controllers dt-bindings: bus: document the stm32 debug bus dt-bindings: pinctrl: document access-controllers property for stm32 HDP dt-bindings: document access-controllers property for coresight peripherals bus: rifsc: fix RIF configuration check for peripherals bus: rifsc: Replace snprintf("%s") with strscpy bus: stm32_firewall: Simplify with scoped for each OF child loop bus: firewall: move stm32_firewall header file in include folderSigned-off-by: Arnd Bergmann List of files: /linux/drivers/bus/stm32_dbg_bus.c
