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.

Linus Torvalds a233bb742a ARM: SoC DT updates
DT changes continue to be the bulk of our merge window contents.
 
 We continue to have a large set of changes across the board as new platforms
 and drivers are added.
 
 Some of the new platforms are:
 - Alphascale ASM9260
 - Marvell Armada 388
 - CSR Atlas7
 - TI Davinci DM816x
 - Hisilicon HiP01
 - ST STiH418
 
 There have also been some sweeping changes, including relicensing of DTS
 contents from GPL to GPLv2+/X11 so that the same files can be reused in
 other non-GPL projects more easily. There's also been changes to the
 DT Makefile to make it a little less conflict-ridden and churny down
 the road.

Jisheng Zhang 5138d5c562 ARM: dts: berlin: correct BG2Q's SM GPIO location.
The gpio4 and gpio5 are in 0xf7fc0000 apb which is located in the SM domain.
This patch moves gpio4 and gpio5 to the correct location. This patch also
renames them as the following to match the names we internally used in
marvell:
	gpio4 -> sm_gpio1
	gpio5 -> sm_gpio0
	porte -> portf
	portf -> porte

This also matches what we did for BG2 and BG2CD's SM GPIO.
