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.

Antoine Tenart f52bf55cba pinctrl: berlin: prepare to use regmap provided by syscon
The Berlin pin controller nodes will be simple-mfd probed sub-nodes of
soc-controller and system-controller nodes. The register bank is managed
by syscon, which provides a regmap.

Prepare to get the regmap from syscon parent node instead of SoC stub
provided regmap.

Antoine Tenart b016d1bd05 pinctrl: berlin: add the BG2 pinctrl driver
Add the pin-controller driver for the Berlin BG2 SoC, with definition
of its groups and functions. Pin control registers are part of chip/
system control registers, which will be represented by a single node.
Until a proper driver for the chip/system control is available,
register the corresponding regmap in pinctrl driver probe.
