Merge tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform updates from Olof Johansson:
"This branch contains part 1 of the platform updates for 3.10. Among
the highlights:
- Support for the new Atmel Cortex-A5 based platforms (SAMA5D3)
- New support for CSR SiRFatlas6 SoCs
- A handful of updates for NVidia T114 (a.k.a. Tegra 4)
- A bunch of updates for the shmobile platforms
- A handful of updates for davinci
- A few updates for Qualcomm MSM
- Plus a handful of other patches, defconfig updates, etc."
