This is a collection of a few late fixes and other misc. stuff that
had dependencies on things being merged from other trees.
The Renesas R-Car power domain handling, and the Nvidia Tegra USB
support both hand notable changes that required changing the DT binding
in a way that only provides compatibility with old DT blobs on new
kernels but not vice versa. As a consequence, the DT changes
are based on top of the driver changes and are now in this branch.
For NXP i.MX and Samsung Exynos, the changes in here depend on
other changes that got merged through the clk maintainer tree.

* Fixed rate and fixed factor clocks do not require an
clock-output-names property.
* Since 07705583e9 ("clk: shmobile: div6: Make clock-output-names
optional") Renesas div6 clocks do not require a clock-output-names
property.
In the above cases there is only one clock output and its name is taken
from that of the clock node.
Accordingly, remove the unnecessary clock-output-names properties and
as necessary the nodes.

This patch enables to use thermal-zone on r8a7790.
This thermal sensor can measure temperature from -40000 to 125000,
but over 117000 can be critical on this chip.
Thus, default critical temperature is now set as 115000 (this driver
is using 5000 steps) (Current critical temperature is using it as
90000, but there is no big reason about it)
And it doesn't check thermal zone periodically (same as current
behavior). You can exchange it by modifying polling-delay[-passive]
property.
You can set trip temp if your kernel has CONFIG_THERMAL_WRITABLE_TRIPS,
but you need to take care to use it, since it will call
orderly_poweroff() it it reaches to the value.

Add the device node for the external SCIF_CLK.
The presence of the SCIF_CLK crystal and its clock frequency depends on
the actual board.
Add the two optional clock sources (ZS_CLK and SCIF_CLK for the internal
resp. external clock) for the Baud Rate Generator for External Clock
(BRG) to all SCIF and HSCIF device nodes.
This increases the range and accuracy of supported baud rates on

Use the new SoC specific binding for rcar-dmac and the generic
binding as a fall-back in the r8a7790 device tree.
In general Renesas hardware is not documented to the extent where the
relationship between IP blocks on different SoCs can be assumed although
they may appear to operate the same way. Furthermore the documentation
typically does not specify a version for individual IP blocks. For these
reasons a convention of using the SoC name in place of a version and
providing SoC-specific compat strings has been adopted.
Although not universally liked this convention is used in the bindings for
most drivers for Renesas hardware. The purpose of this patch is to
update the Renesas R-Car DMA Controller nodes to follow this convention.

Add an appropriate "#power-domain-cells" property to the cpg_clocks
device node, to create the CPG/MSTP Clock Domain.
Add "power-domains" properties to all device nodes for devices that are
part of the CPG/MSTP Clock Domain and can be power-managed through an
MSTP clock. This applies to most on-SoC devices, which have a
one-to-one mapping from SoC device to DT device node. Notable
exceptions are the "display" and "sound" nodes, which represent multiple
SoC devices, each having their own MSTP clocks.

Replace the "arm,cortex-a15-gic" compatible value for the GIC by
"arm,gic-400", as the R-Car Gen2 GIC is assumed to be a GIC-400.
This has been confirmed by reading the GICD_IIDR register (on r8a7791),
which reports 0x0200043b (GIC-400 = 0x02, ARM = 0x43b).
This has no effect on runtime behavior, as currently the GIC driver
treats both compatible values the same.
