The RPI 3 B+ provides control to both LEDs (PWR and ACT). So append
the first letter of the LED color (like in the schematics) in order

According to the schematics for all RPis with a 40 pin header,

clarify that is a I2C bus, append the third letter.

Remove the usage of skeleton.dtsi in the remaining dts files. It was
deprecated since commit 9c0da3cc61f1 ("ARM: dts: explicitly mark
skeleton.dtsi as deprecated"). This will make adding a unit-address to
memory nodes easier.
The main tricky part to removing skeleton.dtsi is we could end up with
no /memory node at all when a bootloader depends on one being present. I
hacked up dtc to check for this condition.

A CPUfreq driver, like the scpi driver used on Juno boards, which
provide the Energy Model with power cost information via the PM_OPP
of_dev_pm_opp_get_cpu_power() function, do need the
dynamic-power-coefficient (C) in the device tree.
Method used to obtain the C value:
C is computed by measuring energy (E) consumption of a frequency domain
(FD) over a 10s runtime (t) sysbench workload running at each Operating
Performance Point (OPP) affine to 1 or 2 CPUs of that FD while the other
CPUs of the system are hotplugged out.
By definition all CPUs of a FD have the the same micro-architecture. An
OPP is characterized by a certain frequency (f) and voltage (V) value.
The corresponding power values (P) are calculated by dividing the delta
of the E values between the runs with 2 and 1 CPUs by t.
With n data tuples (P, f, V), n equal to number of OPPs for this
frequency domain, we can solve C by:
P = Pstat + Pdyn
P = Pstat + CV²f
Cx = (Px - P1)/(Vx²fx - V1²f1) with x = {2, ..., n}
The C value is the arithmetic mean out of {C2, ..., Cn}.
Since DVFS is broken on Juno r1, no dynamic-power-coefficient
information has been added to its dts file.

Fixed Virtual Platforms(FVP) Base RevC model is an emulated Arm platform
with GICv3, PCIe, SMMUv3 and various other features. These are available
free of charge on the Arm Community website at Arm Development
Platforms[1].
It resembles the Foundation Platform, which is a simple FVP that
includes an Armv8‑A AEM processor model but this has two cluster of four
cores, a CCI-550 interconnect, an SMMU and two PCI devices.
In order to enable development of software, let's add a description of
the Revison C version of Base platform.
The documentation for this FVP model is available @[2] for reference.

RTSM/FVP vexpress motherboard model MMCI requires dedicated interrupts
for CMD and PIO, which obviously should be expressed as a list. Current
form uses tuple and it works fine since interrupt-cells equal to 1.

There are macros that exist to indicate the GIC specific flags and
custom cell values as per the GIC DT bindings. It's used in most of the
places in these DTS files but not all. To maintain consistency, lets
use the macros at all the places.
Since DTC doesn't even warn is any cells are missing, it's very hard to
debug if that's the case. Changing to use macros avoids missing cells/
columns.

Add a node for H6 SRAM C1 section.
Manual calls it VE SRAM, but for consistency with older SoCs, SRAM C1
name is used.

This introduces a new compatible for the H6 SRAM C1 section, that is
compatible with the SRAM C1 section as found on the A10.

Add dts node details for Allwinner A64 CSI controller.
A64 CSI has similar features as like in H3, but the CSI_SCLK
need to update it to 300MHz than default clock rate.

The compatible string for the LCD panel used for the Q8 tablets are just
a placeholder that was shown to be compatible with the actual panels
found on these devices. The real panels do not have any identifiable
markings and vary between production runs.
The compatibe string previously used had a pixel clock that could not
be accurately reproduced on Allwinner hardware, and discussions on
whether a margin should be added to the display drivers and how large
a margin was acceptable had stalled.
Now that we have a panel model that is actually used with Allwinner
hardware, has the same dimensions, and the timings have been shown to
work with the nameless panels, we can use that one instead.
