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 ]

Improve the binding example by removing all the leading zeros to fix the
following dtc warnings:
Warning (unit_address_format): Node /XXX unit name should not have leading 0s
Converted using the following command:
perl -p -i -e 's/\@0+([0-9a-f])/\@$1/g' `find ./Documentation/devicetree/bindings "*.txt"`
Some unnecessary changes were manually fixed.

Updates the QMan and BMan device tree bindings for reserved memory
nodes. This makes the reserved memory allocation compatible with

This patch allows the use of IRQ to notify the change of GPIO status
on MPC8xx CPM IO ports. This then allows to associate IRQs to GPIOs
in the Device Tree.
Ex:
CPM1_PIO_C: gpio-controller@960 {
#gpio-cells = <2>;
compatible = "fsl,cpm1-pario-bank-c";
reg = <0x960 0x10>;
fsl,cpm1-gpio-irq-mask = <0x0fff>;
interrupts = <1 2 6 9 10 11 14 15 23 24 26 31>;
interrupt-parent = <&CPM_PIC>;
gpio-controller;
};
The property 'fsl,cpm1-gpio-irq-mask' defines which of the 16 GPIOs
have the associated interrupts defined in the 'interrupts' property.

Move guts devicetree doc to Documentation/devicetree/bindings/soc/fsl/
since it's used by not only PowerPC but also ARM. And add a specification
for 'little-endian' property.

cpm_qe is supported on both powerpc and arm.
and the QE code has been moved from arch/powerpc into
drivers/soc/fsl, so move cpm_qe binding from powerpc/fsl
to soc/fsl

It turns out that existing U-Boots will dereference NULL pointers
if the device tree does not have cell-index in the portal nodes.
No patch has yet been merged adding device tree nodes for this binding
(except a dtsi that has not yet been referenced), nor has any driver
yet been merged making use of the binding, so it's not too late to
change the binding in order to keep compatibility with existing
U-Boots.

The Queue Manager is part of the Data-Path Acceleration Architecture
(DPAA). QMan supports queuing and QoS scheduling of frames to CPUs,
network interfaces and DPAA logic modules, maintains packet ordering
within flows. Besides providing flow-level queuing, is also
responsible for congestion management functions such as RED/WRED,
congestion notifications and tail discards. This binding covers the
CCSR space programming model
