CLK_OUT_A, an external clock output function driven from the clock
control unit, on the R40 is sometimes used to provide a low rate low
power clock to a WiFi or Bluetooth controller.
This patch adds a pinmux setting for it.

UART3 on the PG pingroup on the R40 SoC is commonly used to connect the
bluetooth controller in a WiFi+Bluetooth combo chip, with the WiFi bits
also on the PG pingroup.
This patch adds two device nodes for UART3 on PG pingroup, one for the
RX/TX pins, and one for the RTS/CTS pins. Consumers can reference either
just the RX/TX pinmux setting or both, depending on the application.

The R40 has an RTC hardware block, which has additional registers
that are not related to RTC or clock functions, and is otherwise
compatible with the H3's RTC.
Add a device node for it, and fix up any references to the LOSC.

There are close to 800 indivudal changesets in this branch again, which
feels like a lot. There are particularly many changes for the NVIDIA
Tegra platform this time, in fact more than it has seen in the two years
since the v4.9 merge window. Aside from this, it's been fairly normal,
with lots of changes going into Renesas R-CAR, NXP i.MX, Allwinner Sunxi,
Samsung Exynos, and TI OMAP.
Most of the changes are for adding new features into existing boards,
for brevity I'm only mentioning completely new machines and SoCs here.
For the first time I think we have (slightly) more new 64-bit hardware
than 32-bit:
Two boards get added for TI OMAP: Moxa UC-2101 is an industrial
computer, see https://www.moxa.com/product/UC-2100.htm; GTA04A5
is a minor variation of the motherboards of the GTA04 phone, see
https://shop.goldelico.com/wiki.php?page=GTA04A5
Clearfog is a nice little board for quad-core
Marvell Armada 8040 network processor, see
https://www.solid-run.com/marvell-armada-family/clearfog-gt-8k/
Two additional server boards come with the Aspeed baseboard management
controllers: Stardragon4800 is an arm64 reference platform made by HXT
(based on Qualcomm's server chips), and TiogaPass is an Open Compute
mainboard with x86 CPUs. Both use the ARM11 based AST2500 chips in
the BMC.
NXP i.MX usually sees a lot of new boards each release. This time there
we only add one minor variant: ConnectCore 6UL SBC Pro uses the same
SoM design as the ConnectCore 6UL SBC Express added later. However,
there is a new chip, the i.MX6ULZ, which is an even smaller variant
of the i.MX6ULL, with features removed. There is also support for the
reference board design, the i.MX6ULZ 14x14 EVK.
A new Raspberry Pi variant gets added, this one is the CM3 compute module
based on bcm2837, it was launched in early 2017 but only now added to
the kernel, both as 32-bit and as 64-bit files, as we tend to do for
Raspberry Pi.
On the Allwinner side, everything is again about cheap development
boards, usually of the "Fruit Pi" variety. The new ones this time
are:
Orange Pi Zero Plus2: http://www.orangepi.org/OrangePiZeroPlus2/
Orange Pi One Plus: http://www.orangepi.org/OrangePiOneplus/
Pine64 LTS: https://www.pine64.org/?product=pine-a64-lts
Banana Pi M2+ H5: http://www.banana-pi.org/m2plus.html
The last one of these is now a 64-bit version of the earlier Banana
Pi M2+ H3, with the same board layout.
Similarly, for Rockchips, get get another variant of the 32-bit
Asus Tinker board, the model 'S' based on rk3288, and three now
boards based on the popular RK3399 chip:
ROC-RK3399-PC: https://libre.computer/products/boards/roc-rk3399-pc/
Rock960: https://www.96boards.org/product/rock960/
RockPro64: https://www.pine64.org/?page_id=61454
These are all quite powerful boards with lots of RAM and I/O, and
the RK3399 is the same chip used in several Chromebooks. Finally,
we get support for the PX30 (aka rk3326) chip, which is based on the
low-end 64-bit Cortex-A35 CPU core. So far, only the evaluation board
is supported.
One more Banana Pi is added with a Mediatek chip: Banana Pi R64 is based
on the MT7622 WiFi router platform, and the first product I've seen with
a 64-bit Mediatek chip in that market: http://www.banana-pi.org/r64.html
For HiSilicon, we gain support for the Hi3670 SoC and HiKey 370
development board, which are similar to the Hi3660 and Hikey 360
respectively, but add support for an NPU.
Amlogic gets initial support for the Meson-G12A chip (S905D2),
another quad-core Cortex-A53 SoC, and its evaluation platform.
On the 32-bit side, we gain support for an actual end-user product,
the Endless Computers Endless Mini based on Meson8b (S805), see
https://endlessos.com/computers/
Qualcomm adds support for their MSM8998 SoC and evaluation platform. This
chip is commonly known as the Snapdragon 835, and is used in high-end
phones as well as low-end laptops.
For Renesas, a very bare support for the r8a774a1 (RZ/G2M) is added,
but no boards for this one. However, we do add boards for the previously
added r8a77965 (R-Car M3-N): the M3NULCB Kingfisher and the M3NULCB
Starter Kit Pro.
While we have lots of DT changes for NVIDIA to update the existing files,
the only board that gets added is the Toradex Colibri T20 on Colibri
Evaluation Board for the old Tegra2.
Synaptics add support for their AS370 SoC, which is part of the (formerly
Marvell) Berlin line of set-top-box chips used e.g. in the various Google
Chromecast. Only the .dtsi gets added at this point, no actual machines.
