Merge tag 'arm-drivers-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC driver updates from Arnd Bergmann: "Updates for SoC specific drivers include a few subsystems that have their own maintainers but send them through the soc tree: TEE/OP-TEE: - Add tracepoints around calls to secure world Memory controller drivers: - Minor fixes for Renesas, Exynos, Mediatek and Tegra platforms - Add debug statistics to Tegra20 memory controller - Update Tegra bindings and convert to dtschema ARM SCMI Firmware: - Support for modular SCMI protocols and vendor specific extensions - New SCMI IIO driver - Per-cpu DVFS The other driver changes are all from the platform maintainers directly and reflect the drivers that don't fit into any other subsystem as well as treewide changes for a particular platform. SoCFPGA: - Various cleanups contributed by Krzysztof Kozlowski Mediatek: - add MT8183 support to mutex driver - MMSYS: use per SoC array to describe the possible routing - add MMSYS support for MT8183 and MT8167 - add support for PMIC wrapper with integrated arbiter - add support for MT8192/MT6873 Tegra: - Bug fixes to PMC and clock drivers NXP/i.MX: - Update SCU power domain driver to keep console domain power on. - Add missing ADC1 power domain to SCU power domain driver. - Update comments for single global power domain in SCU power domain driver. - Add i.MX51/i.MX53 unique id support to i.MX SoC driver. NXP/FSL SoC driver updates for v5.13 - Add ACPI support for RCPM driver - Use generic io{read,write} for QE drivers after performance optimized for PowerPC - Fix QBMAN probe to cleanup HW states correctly for kexec - Various cleanup and style fix for QBMAN/QE/GUTS drivers OMAP: - Preparation to use devicetree for genpd - ti-sysc needs iorange check improved when the interconnect target module has no control registers listed - ti-sysc needs to probe l4_wkup and l4_cfg interconnects first to avoid issues with missing resources and unnecessary deferred probe - ti-sysc debug option can now detect more devices - ti-sysc now warns if an old incomplete devicetree data is found as we now rely on it being complete for am3 and 4 - soc init code needs to check for prcm and prm nodes for omap4/5 and dra7 - omap-prm driver needs to enable autoidle retention support for omap4 - omap5 clocks are missing gpmc and ocmc clock registers - pci-dra7xx now needs to use builtin_platform_driver instead of using builtin_platform_driver_probe for deferred probe to work Raspberry Pi: - Fix-up all RPi firmware drivers so as for unbind to happen in an orderly fashion - Support for RPi's PoE hat PWM bus Qualcomm - Improved detection for SCM calling conventions - Support for OEM specific wifi firmware path - Added drivers for SC7280/SM8350: RPMH, LLCC< AOSS QMP" * tag 'arm-drivers-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (165 commits) soc: aspeed: fix a ternary sign expansion bug memory: mtk-smi: Add device-link between smi-larb and smi-common memory: samsung: exynos5422-dmc: handle clk_set_parent() failure memory: renesas-rpc-if: fix possible NULL pointer dereference of resource clk: socfpga: fix iomem pointer cast on 64-bit soc: aspeed: Adapt to new LPC device tree layout pinctrl: aspeed-g5: Adapt to new LPC device tree layout ipmi: kcs: aspeed: Adapt to new LPC DTS layout ARM: dts: Remove LPC BMC and Host partitions dt-bindings: aspeed-lpc: Remove LPC partitioning soc: fsl: enable acpi support in RCPM driver soc: qcom: mdt_loader: Detect truncated read of segments soc: qcom: mdt_loader: Validate that p_filesz < p_memsz soc: qcom: pdr: Fix error return code in pdr_register_listener firmware: qcom_scm: Fix kernel-doc function names to match firmware: qcom_scm: Suppress sysfs bind attributes firmware: qcom_scm: Workaround lack of "is available" call on SC7180 firmware: qcom_scm: Reduce locking section for __get_convention() firmware: qcom_scm: Make __qcom_scm_is_call_available() return bool Revert "soc: fsl: qe: introduce qe_io{read,write}* wrappers" ...
