Merge tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform changes from Arnd Bergmann: "New and updated SoC support. Among the things new for this release are: - at91: Added support for the new SAMA5D4 SoC, following the earlier SAMA5D3 - bcm: Added support for BCM63XX family of DSL SoCs - hisi: Added support for HiP04 server-class SoC - meson: Initial support for the Amlogic Meson6 (aka 8726MX) platform - shmobile: added support for new r8a7794 (R-Car E2) automotive SoC Noteworthy changes to existing SoC support are: - imx: convert i.MX1 to device tree - omap: lots of power management work - omap: base support to enable moving to standard UART driver - shmobile: lots of progress for multiplatform support, still ongoing" * tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (171 commits) ARM: hisi: depend on ARCH_MULTI_V7 CNS3xxx: Fix debug UART.
