Merge tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform changes from Olof Johansson:
"New and updated SoC support. Among the things new for this release
are:
- More support for the AM33xx platforms from TI
- Tegra 124 support, and some updates to older tegra families as well
- imx cleanups and updates across the board
- A rename of Broadcom's Mobile platforms which were introduced as
ARCH_BCM, and turned out to be too broad a name. New name is
ARCH_BCM_MOBILE.
- A whole bunch of updates and fixes for integrator, making the
platform code more modern and switches over to DT-only booting.
- Support for two new Renesas shmobile chipsets. Next up for them is
more work on consolidation instead of introduction of new
non-multiplatform SoCs, we're all looking forward to that!
- Misc cleanups for older Samsung platforms, some Allwinner updates,
etc"
