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:
"The main addition this time around is the new ARM "SCMI" framework,
which is the latest in a series of standards coming from ARM to do
power management in a platform independent way.
This has been through many review cycles, and it relies on a rather
interesting way of using the mailbox subsystem, but in the end I
agreed that Sudeep's version was the best we could do after all.
Other changes include:
- the ARM CCN driver is moved out of drivers/bus into drivers/perf,
which makes more sense. Similarly, the performance monitoring
portion of the CCI driver are moved the same way and cleaned up a
little more.
- a series of updates to the SCPI framework
- support for the Mediatek mt7623a SoC in drivers/soc
- support for additional NVIDIA Tegra hardware in drivers/soc
- a new reset driver for Socionext Uniphier
- lesser bug fixes in drivers/soc, drivers/tee, drivers/memory, and
drivers/firmware and drivers/reset across platforms"
