"This release brings up a new platform based on the old ARM9 core: the
Nuvoton NPCM is used as a baseboard management controller, competing
with the better known ASpeed AST2xx series.
Another important change is the addition of ARMv7-A based chips in
mach-stm32. The older parts in this platform are ARMv7-M based
microcontrollers, now they are expanding to general-purpose workloads.
The other changes are the usual defconfig updates to enable additional
drivers, lesser bugfixes. The largest updates as often are the ongoing
OMAP cleanups, but we also have a number of changes for the older PXA
and davinci platforms this time.
For the Renesas shmobile/r-car platform, some new infrastructure is
needed to make the watchdog work correctly.
Supporting Multiprocessing on Allwinner A80 required a significant
amount of new code, but is not doing anything unexpected"

01d675f159 ARM: shmobile: rcar-gen2: Add watchdog support
58adf1ba0d ARM: shmobile: Add watchdog support
* SoC
- Identify R-Car V3H (r8a77980) and M3N (r8a77965)
- Enable R-Car Gen2 regulator quirk for Stout board with H3 (r8a7790) SoC
Marek Vaust says "Regulator setup is suboptimal on H2 Stout too. The
Stout newly has two DA9210 regulators, so the quirk is extended to
handle another DA9210 at i2c address 0x70."
- Add watchdog support
This is the SoC portion of the following solution. It is not yet
enabled in DT as it is not functional without clock dependencies
in place.
Fabrizio Castro says "this series has been around for some time as RFC,
and it has collected useful comments from the community along the way.
The solution proposed by this patch set works for most R-Car Gen2 and
RZ/G1 devices, but not all of them. We now know that for some R-Car
Gen2 early revisions there is no proper software fix. Anyway, no
product has been built around early revisions, but development boards
mounting early revisions (basically prototypes) are still out there.
As a result, this series isn't enabling the internal watchdog on R-Car
Gen2 boards, developers may enable it in board specific device trees if
needed. This series has been tested by me on the iwg20d, iwg22d,
Lager, Alt, and Koelsch boards.
The problem
===========
To deal with SMP on R-Car Gen2 and RZ/G1, we install a reset vector to
ICRAM1 and we program the [S]BAR registers so that when we turn ON the
non-boot CPUs they are redirected to the reset vector installed by Linux
in ICRAM1, and eventually they continue the execution to RAM, where the
SMP bring-up code will take care of the rest. The content of the [S]BAR
registers survives a watchdog triggered reset, and as such after the
watchdog fires the boot core will try and execute the SMP bring-up code
instead of jumping to the bootrom code.
The fix
=======
The main strategy for the solution is to let the reset vector decide if
it needs to jump to shmobile_boot_fn or to the bootrom code. In a
watchdog triggered reset scenario, since the [S]BAR registers keep their
values, the boot CPU will jump into the newly designed reset vector, the
assembly routine will eventually test WOVF (a bit in register RWTCSRA
that indicates if the watchdog counter has overflown, the value of this
bit gets retained in this scenario), and jump to the bootrom code which
will in turn load up the bootloader, etc. When bringing up SMP or using
CPU hotplug, the reset vector will jump to shmobile_boot_fn instead."

- Add support for R-Car V3H (r8a77980) and V3H (r8a77980)

Geert Uytterhoeven says "This frees another 1764 bytes
(arm32/shmobile_defconfig) or 1000 bytes (arm64/renesas_defconfig) of
memory after kernel init."
- Fix power area parents
Sergei Shtylyov says "According to the figure 9.2(b) of the R-Car
Series, 3rd Generation User’s Manual: Hardware Rev. 0.80 the A2IRn and
A2SCn power areas in R8A77970 have the A3IR area as a parent, thus the
SYSC driver has those parents wrong.."

Pull "Few omap interconnect dts fixes for v4.16 merge window" from
Tony Lindgren:
Now that we have the dts clocks for the clkctrl clock and the
interconnect binding, we need to update the existing ti-sysc
users according to the binding to make it usable for drivers.
Apologies for not being able to send this earlier but it took
me few revisions to get the smartreflex changes right and
tested with yet to be posted patches to make smartreflex probe
with dts and I wanted to have it sit in next for a while to make
sure we're not introducing regressions for legacy platform data
based booting.
Note that this is based on a merge with commit 20a2742e57
("dt-bindings: ti-sysc: Update binding for timers and capabilities")
to avoid a merge conflict with the binding changes.

ARM: dts: Update ti-sysc data for existing users
ARM: dts: Fix smartreflex compatible for omap3 shared mpu-iva instance
dt-bindings: ti-sysc: Update binding for timers and capabilities
The smartreflex instance for mpu and iva is shared. Let's fix this as I've
already gotten confused myself few times wondering where the mpu instance
is. Note that we are still probing the driver using platform data so this
change is safe to do.

Devices have inter-dependencies some times. For example a device that
needs to run at 800 MHz, needs another device (e.g. Its power domain) to
be configured at a particular operating performance point.
This patch introduces a new property "required-opp" which can be present
directly in a device's node (if it doesn't need to change its OPPs), or
in device's OPP nodes. More details on the property can be seen in the
binding itself.

Power-domains can also have their active states and this patch enhances
the OPP binding to define those. The power domains can use the OPP
bindings as is, with one additional change to Allow
"operating-points-v2" property to contain multiple phandles for power
domain providers providing multiple domains.

Pull ARM SoC driver updates from Arnd Bergmann:
"This branch contains platform-related driver updates for ARM and
ARM64, these are the areas that bring the changes:
New drivers:
- driver support for Renesas R-Car V3M (R8A77970)
- power management support for Amlogic GX
- a new driver for the Tegra BPMP thermal sensor
- a new bus driver for Technologic Systems NBUS
Changes for subsystems that prefer to merge through arm-soc:
- the usual updates for reset controller drivers from Philipp Zabel,
with five added drivers for SoCs in the arc, meson, socfpa,
uniphier and mediatek families
- updates to the ARM SCPI and PSCI frameworks, from Sudeep Holla,
Heiner Kallweit and Lorenzo Pieralisi
Changes specific to some ARM-based SoC
- the Freescale/NXP DPAA QBMan drivers from PowerPC can now work on
ARM as well
- several changes for power management on Broadcom SoCs
- various improvements on Qualcomm, Broadcom, Amlogic, Atmel,
Mediatek
- minor Cleanups for Samsung, TI OMAP SoCs"
[ NOTE! This doesn't work without the previous ARM SoC device-tree pull,
because the R8A77970 driver is missing a header file that came from
that pull.
The fact that this got merged afterwards only fixes it at this point,
and bisection of that driver will fail if/when you walk into the
history of that driver. - Linus ]

Pull "non-urgent device tree fixes for omaps for v4.15 merge window"
from Tony Lindgren
Non-urgent device tree fixes for omaps that can all wait for v4.15
merge window.
Turns out that we have many devices working just because we have
the legacy platform data still around. This is mostly an issue
for omap4, other SoCs just have minimal fixes needed.
As many of the missing device tree nodes and properties are for
devices that have no drivers in the mainline kernel, such as
slimbus, iss, mcasp, aess, fdif and gpu, we might as well start
using the new "ti,sysc" interconnect target module binding for
them so we can get the devices with no child device drivers idled.
This also makes it possible to drop unnecessary platform data
in later patches.

ARM: dts: Add missing dma hwmods property for omap3
We are missing smartreflex device tree nodes for omap4 with
their related "ti,hwmods" properties that the SoC interconnect
code needs.
Note that this will only show up as a bug with "doesn't have
mpu register target base" boot errors when the legacy platform
data is removed.
And since we're missing the device tree binding for smartreflex,
let's also add it and document the existing omap3 use too.
Note that the related driver also needs to be updated to probe
using device tree and get the platform data passed to it using
auxdata with arch/arm/mach-omap2/pdata-quirks.c.
