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: "New SoC specific drivers: - NVIDIA Tegra PM Domain support for newer SoCs (Tegra186 and later) based on the "BPMP" firmware - Clocksource and system controller drivers for the newly added Action Semi platforms (both arm and arm64). Reset subsystem, merged through arm-soc by tradition: - New drivers for Altera Stratix10, TI Keystone and Cortina Gemini SoCs - Various subsystem-wide cleanups Updates for existing SoC-specific drivers - TI GPMC (General Purpose Memory Controller) - Mediatek "scpsys" system controller support for MT6797 - Broadcom "brcmstb_gisb" bus arbitrer - ARM SCPI firmware - Renesas "SYSC" system controller One more driver update was submitted for the Freescale/NXP DPAA data path acceleration that has previously been used on PowerPC chips. I ended up postponing the merge until some API questions for its unusual MMIO access are resolved" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (35 commits) clocksource: owl: Add S900 support clocksource: Add Owl timer soc: renesas: rcar-sysc: Use GENPD_FLAG_ALWAYS_ON firmware: tegra: Fix locking bugs in BPMP soc/tegra: flowctrl: Fix error handling soc/tegra: bpmp: Implement generic PM domains soc/tegra: bpmp: Update ABI header PM / Domains: Allow overriding the ->xlate() callback soc: brcmstb: enable drivers for ARM64 and BMIPS soc: renesas: Rework Kconfig and Makefile logic reset: Add the TI SCI reset driver dt-bindings: reset: Add TI SCI reset binding reset: use kref for reference counting soc: qcom: smsm: Improve error handling, quiesce probe deferral cpufreq: scpi: use new scpi_ops functions to remove duplicate code firmware: arm_scpi: add support to populate OPPs and get transition latency dt-bindings: reset: Add reset manager offsets for Stratix10 memory: omap-gpmc: add error message if bank-width property is absent memory: omap-gpmc: make dts snippet include semicolon reset: Add a Gemini reset controller ...
