Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC-related driver updates from Olof Johansson: "Various driver updates for platforms and a couple of the small driver subsystems we merge through our tree: Among the larger pieces: - Power management improvements for TI am335x and am437x (RTC suspend/wake) - Misc new additions for Amlogic (socinfo updates) - ZynqMP FPGA manager - Nvidia improvements for reset/powergate handling - PMIC wrapper for Mediatek MT8516 - Misc fixes/improvements for ARM SCMI, TEE, NXP i.MX SCU drivers" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (57 commits) soc: aspeed: fix Kconfig soc: add aspeed folder and misc drivers spi: zynqmp: Fix build break soc: imx: Add generic i.MX8 SoC driver MAINTAINERS: Update email for Qualcomm SoC maintainer memory: tegra: Fix a typos for "fdcdwr2" mc client Revert "ARM: tegra: Restore memory arbitration on resume from LP1 on Tegra30+" memory: tegra: Replace readl-writel with mc_readl-mc_writel memory: tegra: Fix integer overflow on tick value calculation memory: tegra: Fix missed registers values latching ARM: tegra: cpuidle: Handle tick broadcasting within cpuidle core on Tegra20/30 optee: allow to work without static shared memory soc/tegra: pmc: Move powergate initialisation to probe soc/tegra: pmc: Remove reset sysfs entries on error soc/tegra: pmc: Fix reset sources and levels soc: amlogic: meson-gx-pwrc-vpu: Add support for G12A soc: amlogic: meson-gx-pwrc-vpu: Fix power on/off register bitmask fpga manager: Adding FPGA Manager support for Xilinx zynqmp dt-bindings: fpga: Add bindings for ZynqMP fpga driver firmware: xilinx: Add fpga API's ...
