Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver updates from Arnd Bergmann: "The main addition this time around is the new ARM "SCMI" framework, which is the latest in a series of standards coming from ARM to do power management in a platform independent way. This has been through many review cycles, and it relies on a rather interesting way of using the mailbox subsystem, but in the end I agreed that Sudeep's version was the best we could do after all. Other changes include: - the ARM CCN driver is moved out of drivers/bus into drivers/perf, which makes more sense. Similarly, the performance monitoring portion of the CCI driver are moved the same way and cleaned up a little more. - a series of updates to the SCPI framework - support for the Mediatek mt7623a SoC in drivers/soc - support for additional NVIDIA Tegra hardware in drivers/soc - a new reset driver for Socionext Uniphier - lesser bug fixes in drivers/soc, drivers/tee, drivers/memory, and drivers/firmware and drivers/reset across platforms" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (87 commits) reset: uniphier: add ethernet reset control support for PXs3 reset: stm32mp1: Enable stm32mp1 reset driver dt-bindings: reset: add STM32MP1 resets reset: uniphier: add Pro4/Pro5/PXs2 audio systems reset control reset: imx7: add 'depends on HAS_IOMEM' to fix unmet dependency reset: modify the way reset lookup works for board files reset: add support for non-DT systems clk: scmi: use devm_of_clk_add_hw_provider() API and drop scmi_clocks_remove firmware: arm_scmi: prevent accessing rate_discrete uninitialized hwmon: (scmi) return -EINVAL when sensor information is unavailable amlogic: meson-gx-socinfo: Update soc ids soc/tegra: pmc: Use the new reset APIs to manage reset controllers soc: mediatek: update power domain data of MT2712 dt-bindings: soc: update MT2712 power dt-bindings cpufreq: scmi: add thermal dependency soc: mediatek: fix the mistaken pointer accessed when subdomains are added soc: mediatek: add SCPSYS power domain driver for MediaTek MT7623A SoC soc: mediatek: avoid hardcoded value with bus_prot_mask dt-bindings: soc: add header files required for MT7623A SCPSYS dt-binding dt-bindings: soc: add SCPSYS binding for MT7623 and MT7623A SoC ...
