Merge tag 'soc-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform changes from Olof Johansson:
"This is the bulk of new SoC enablement and other platform changes for
3.17:
- Samsung S5PV210 has been converted to DT and multiplatform
- Clock drivers and bindings for some of the lower-end i.MX 1/2
platforms
- Kirkwood, one of the popular Marvell platforms, is folded into the
mvebu platform code, removing mach-kirkwood
- Hwmod data for TI AM43xx and DRA7 platforms
- More additions of Renesas shmobile platform support
- Removal of plat-samsung contents that can be removed with S5PV210
being multiplatform/DT-enabled and the other two old platforms
being removed
New platforms (most with only basic support right now):
- Hisilicon X5HD2 settop box chipset is introduced
- Mediatek MT6589 (mobile chipset) is introduced
- Broadcom BCM7xxx settop box chipset is introduced
+ as usual a lot other pieces all over the platform code"
