Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC platform updates from Olof Johansson: "SoC updates, mostly refactorings and cleanups of old legacy platforms. Major themes this release: - Conversion of ixp4xx to a modern platform (drivers, DT, bindings) - Moving some of the ep93xx headers around to get it closer to multiplatform enabled. - Cleanups of Davinci This also contains a few patches that were queued up as fixes before 5.1 but I didn't get sent in before release" * tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (123 commits) ARM: debug-ll: add default address for digicolor ARM: u300: regulator: add MODULE_LICENSE() ARM: ep93xx: move private headers out of mach/* ARM: ep93xx: move pinctrl interfaces into include/linux/soc ARM: ep93xx: keypad: stop using mach/platform.h ARM: ep93xx: move network platform data to separate header ARM: stm32: add AMBA support for stm32 family MAINTAINERS: update arch/arm/mach-davinci ARM: rockchip: add missing of_node_put in rockchip_smp_prepare_pmu ARM: dts: Add queue manager and NPE to the IXP4xx DTSI soc: ixp4xx: qmgr: Add DT probe code soc: ixp4xx: qmgr: Add DT bindings for IXP4xx qmgr soc: ixp4xx: npe: Add DT probe code soc: ixp4xx: Add DT bindings for IXP4xx NPE soc: ixp4xx: qmgr: Pass resources soc: ixp4xx: Remove unused functions soc: ixp4xx: Uninline several functions soc: ixp4xx: npe: Pass addresses as resources ARM: ixp4xx: Turn the QMGR into a platform device ARM: ixp4xx: Turn the NPE into a platform device ...

+ bool "Trusted Foundations secure monitor support"
+ depends on ARM
+ help
+ Some devices (including most early Tegra-based consumer devices on
+ the market) are booted with the Trusted Foundations secure monitor
+ active, requiring some core operations to be performed by the secure
+ monitor instead of the kernel.
+
+ This option allows the kernel to invoke the secure monitor whenever
+ required on devices using Trusted Foundations. See the functions and
+ comments in linux/firmware/trusted_foundations.h or the device tree
+ bindings for "tlm,trusted-foundations" for details on how to use it.
