Linus Torvalds b240b419db ARM: SoC device tree updates for 4.17 
This is the usual set of changes for device trees, with over 700
 non-merged changesets. There is an ongoing set of dtc warning fixes and
 the usual bugfixes, cleanups and added device support.
 
 The most interesting bit as usual is support for new machines listed
 below:
 
 - The Allwinner H6 makes its debut with the Pine-H64 board, and we get
   two new machines based on its older siblings: the H5 based OrangePi
   Zero+ and the A64 based Teres-I Laptop from Olimex. On the 32-bit side,
   we add The Olimex som204 based on Allwinner A20, and the Banana Pi M2
   Zero development board (based on H2).
 
 - NVIDIA adds support for Tegra194 aka "Xavier", plus their p2972
   development board and p2888 CPU module.
 
 - The Nuvoton npcm750 is a BMC that was newly added, for now we only
   support running on the evaluation board.
 
 - STmicroelectronics stm32 gains support for the stm32mp157c and two
   evaluation boards.
 
 - The Toradex Colibri board family grows a few members based on the
   i.MX6ULL variant.
 
 - The Advantec DMS-BA16 is a Qseven module using the NXP i.MX6
   family of chips.
 
 - The Phytec phyBOARD Mira is a family of industrial boards based on
   i.MX6. For now, four models get added.
 
 - TI am335x based PDU-001 is an industrial embedded machine used for
   traffic monitoring
 
 - The Aspeed platform now supports running on the BMC on the Qualcomm
   Centriq 2400 server
 
 - Samsung Exynos4 based Galaxy S3 is a family of mobile phones Qualcomm
   msm8974 based Galaxy S5 is a rather different phone made by the same
   company.
 
 - The Xilinx Zynq and ZynqMP platforms now gained a lot of dts file
   for the various boards made by Xilinx themselves, as well as the
   Digilent Zybo Z7.
 
 - The ARM Versatile family now supports the "IB2" interface board.
 
 - The Renesas H2 based "Stout" and the H3 based Salvator-X are more
   evaluation boards named after a kind of beer, as most of them are.
   The r8a77980 (V3H) based "Condor" apparently doesn't follow that
   tradition. ;-)
 
 - ROC-RK3328-CC is a simple developement board from the Libre Computer
   Project, based on the Rockchips RK3328 SoC
 
 - Haiku is another development board plus Qseven module based on Rockchips
   RK3368 and made by Theobroma Systems.

/*
* Power Tree
*
* In general an attempt is made to include all rails called out by
* the schematic as long as those rails interact in some way with
* the AP. AKA:
* - Rails that only connect to the EC (or devices that the EC talks to)
* are not included.
* - Rails _are_ included if the rails go to the AP even if the AP
* doesn't currently care about them / they are always on. The idea
* here is that it makes it easier to map to the schematic or extend
* later.
*
* If two rails are substantially the same from the AP's point of
* view, though, we won't create a full fixed regulator. We'll just
* put the child rail as an alias of the parent rail. Sometimes rails
* look the same to the AP because one of these is true:
* - The EC controls the enable and the EC always enables a rail as
* long as the AP is running.
* - The rails are actually connected to each other by a jumper and
* the distinction is just there to add clarity/flexibility to the
* schematic.

/*
* Set some suspend operating points to avoid OVP in suspend
*
* When we go into S3 ARM Trusted Firmware will transition our PWM regulators
* from wherever they're at back to the "default" operating point (whatever
* voltage we get when we set the PWM pins to "input").
*
* This quick transition under light load has the possibility to trigger the
* regulator "over voltage protection" (OVP).
*
* To make extra certain that we don't hit this OVP at suspend time, we'll
* transition to a voltage that's much closer to the default (~1.0 V) so that
* there will not be a big jump. Technically we only need to get within 200 mV
* of the default voltage, but the speed here should be fast enough and we need
* suspend/resume to be rock solid.
