Harmless mistake, but it's incorrect. The DT spec provides recommendations
for the node names:
"The name of a node should be somewhat generic, reflecting the function
of the device and not its precise programming model. If appropriate, the
name should be one of the following choices:
...
interrupt-controller"

The LVDS0 encoder on Koelsh and Porter, and the LVDS1 encoder on Lager,
are enabled in DT but have no device connected to their output. This
result in spurious messages being printed to the kernel log such as

Althought interface SDHI1 found on the RZ/G1C SoC (a.k.a.
r8a77470) is compatible with the R-Car Gen3 ones, its OF
compatibility is restricted to the SoC specific compatible
string to avoid confusion, as from a more generic perspective
the RZ/G1C is sharing the most similarities with the R-Car
Gen2 family of SoCs, and there is a combination of R-Car
Gen2 compatible SDHI IPs and R-Car Gen3 compatible SDHI IP
on this specific chip.
This patch adds the SoC specific part of SDHI1 support, and
since SDHI1 comes with internal DMA, its DT node looks fairly
different from SDHI0 and SDHI2.

RZ/G1C comes with two different types of IP for the SDHI
interfaces, SDHI0 and SDHI2 share the same IP type, and
such an IP is also compatible with the one found in R-Car
Gen2. SDHI1 IP on the other hand is compatible with R-Car
Gen3 with internal DMA.
This patch completes the SDHI support of the R-Car Gen2
compatible IPs, including fixing the max-frequency
definition of SDHI2, as it turns out there is a bug in
Section 1.3.9 of the RZ/G1C Hardware User's Manual (Rev.
1.00 Oct. 2017).

All our pinctrl nodes were using a node name convention with a unit-address
to differentiate the different muxing options. However, since those nodes
didn't have a reg property, they were generating warnings in DTC.
In order to accomodate for this, convert the old nodes to the syntax we've
been using for the new SoCs, including removing the letter suffix of the
node labels to the bank of those pins to make things more readable.

One of the usage of the LRADC is to implement buttons. The bindings define
that we should have one subnode per button, with their associated voltage
as a property.
However, there was no reg property but we still used the voltage associated
to the button as the unit-address, which eventually generated warnings in
DTC.
Rename the node names to avoid those warnings.

Each CPU can (and does) participate in cooling down the system but the
DT only captures a handful of them, normally CPU0, in the cooling maps.
Things work by chance currently as under normal circumstances its the
first CPU of each cluster which is used by the operating systems to
probe the cooling devices. But as soon as this CPU ordering changes and
any other CPU is used to bring up the cooling device, we will start
seeing failures.
Also the DT is rather incomplete when we list only one CPU in the
cooling maps, as the hardware doesn't have any such limitations.
Update cooling maps to include all devices affected by individual trip
points.

Add nodes for i2s, digital and analog parts of audiocodec on A64.
The routing paths listed are entries connecting the digital and analog
side of the audio codec together. Due to how device tree works, these
must be copied over to each board device tree, in addition to any board
level routes.
The oversampling rate is set to 128, so that when playing back 192 kHz
audio samples, the MCLK runs at the same rate as the module clock, at
24.576 MHz.
The user manual suggests using different oversampling rates for different
sample rates, but that's not possible without a platform-specific machine
driver.

* Do not describe the device as compatible with "renesas,rcar-gen3-iic" or
