Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson: - A revert of all SCPI changes from the 4.15 merge window. They had regressions on the Amlogic platforms, and the submaintainer isn't around to fix these bugs due to vacation, etc. So we agreed to revert and revisit in next release cycle. - A series fixing a number of bugs for ARM CCN interconnect, around module unload, smp_processor_id() in preemptable context, and fixing some memory allocation failure checks. - A handful of devicetree fixes for different platforms, fixing warnings and errors that were previously ignored by the compiler. - The usual set of mostly minor fixes for different platforms. * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (42 commits) ARM64: dts: meson-gx: fix UART pclk clock name ARM: omap2: hide omap3_save_secure_ram on non-OMAP3 builds arm: dts: nspire: Add missing #phy-cells to usb-nop-xceiv ARM: dts: Fix dm814x missing phy-cells property ARM: dts: Fix elm interrupt compiler warning bus: arm-ccn: fix module unloading Error: Removing state 147 which has instances left. bus: arm-cci: Fix use of smp_processor_id() in preemptible context bus: arm-ccn: Fix use of smp_processor_id() in preemptible context bus: arm-ccn: Simplify code bus: arm-ccn: Check memory allocation failure bus: arm-ccn: constify attribute_group structures. firmware: arm_scpi: Revert updates made during v4.15 merge window arm: dts: marvell: Add missing #phy-cells to usb-nop-xceiv arm64: dts: sort vendor subdirectories in Makefile alphabetically meson-gx-socinfo: Fix package id parsing ARM: meson: fix spelling mistake: "Couln't" -> "Couldn't" ARM: dts: meson: fix the memory region of the GPIO interrupt controller ARM: dts: meson: correct the sort order for the the gpio_intc node MAINTAINERS: exclude other Socionext SoC DT files from ARM/UNIPHIER entry arm64: dts: uniphier: remove unnecessary interrupt-parent ...
