Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver updates from Arnd Bergmann:
"A number of new drivers get added this time, along with many
low-priority bugfixes. The most interesting changes by subsystem are:
bus drivers:
- Updates to the Broadcom bus interface driver to support newer SoC
types
- The TI OMAP sysc driver now supports updated DT bindings
memory controllers:
- A new driver for Tegra186 gets added
- A new driver for the ti-emif sram, to allow relocating
suspend/resume handlers there
SoC specific:
- A new driver for Qualcomm QMI, the interface to the modem on MSM
SoCs
- A new driver for power domains on the actions S700 SoC
- A driver for the Xilinx Zynq VCU logicoreIP
reset controllers:
- A new driver for Amlogic Meson-AGX
- various bug fixes
tee subsystem:
- A new user interface got added to enable asynchronous communication
with the TEE supplicant.
- A new method of using user space memory for communication with the
TEE is added"
