Linus Torvalds f5dcb68086 ARM: SoC: driver updates for v4.2 
Some of these are for drivers/soc, where we're now putting
 SoC-specific drivers these days. Some are for other driver subsystems
 where we have received acks from the appropriate maintainers.
 
 Some highlights:
 
 - simple-mfd: document DT bindings and misc updates
 - migrate mach-berlin to simple-mfd for clock, pinctrl and reset
 - memory: support for Tegra132 SoC
 - memory: introduce tegra EMC driver for scaling memory frequency
 - misc. updates for ARM CCI and CCN busses
 
  Conflicts:
 	arch/arm64/boot/dts/arm/juno-motherboard.dtsi
 
  Trivial add/add conflict with our dt branch.
  Resolution: take both sides.
