Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC driver updates from Olof Johansson:
"Various driver updates for platforms:
- A larger set of work on Tegra 2/3 around memory controller and
regulator features, some fuse cleanups, etc..
- MMP platform drivers, in particular for USB PHY, and other smaller
additions.
- Samsung Exynos 5422 driver for DMC (dynamic memory configuration),
and ASV (adaptive voltage), allowing the platform to run at more
optimal operating points.
- Misc refactorings and support for RZ/G2N and R8A774B1 from Renesas
- Clock/reset control driver for TI/OMAP
- Meson-A1 reset controller support
- Qualcomm sdm845 and sda845 SoC IDs for socinfo"
