Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC-related driver updates from Olof Johansson:
"Various driver updates for platforms:
- Nvidia: Fuse support for Tegra194, continued memory controller
pieces for Tegra30
- NXP/FSL: Refactorings of QuickEngine drivers to support
ARM/ARM64/PPC
- NXP/FSL: i.MX8MP SoC driver pieces
- TI Keystone: ring accelerator driver
- Qualcomm: SCM driver cleanup/refactoring + support for new SoCs.
- Xilinx ZynqMP: feature checking interface for firmware. Mailbox
communication for power management
- Overall support patch set for cpuidle on more complex hierarchies
(PSCI-based)
and misc cleanups, refactorings of Marvell, TI, other platforms"
