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"
