Add entries for the MT8186 based Chromebooks, also collectively known
as the Lenovo IdeaPad Slim 3 Chromebook (14M868). It is also based on
the "Steelix" design. Being a laptop instead of a convertible device,
there is no stylus, which is similar to Rusty. However Magneton does
not have ports on the right side of the device.
Three variants are listed separately. These use different touchscreen
controllers, or lack a touchscreen altogether.

The MT8186 Steelix, also known as the Lenovo 300e Yoga Chromebook Gen 4,
is a convertible device based on a common design of the same name. The
device comes in different variants. Of them, whether a world facing
camera is integrated is the only differentiating factor between the
two device trees added. The different SKU IDs describe this alone.
The other device difference is the trackpad component used. This is
simply handled by having both possible components described in the
device tree, and letting the implementation figure out which one is
actually available. The system bootloader / firmware does not
differentiate this in that they share the same SKU IDs.

Tentacruel and Tentacool are MT8186 based Chromebooks based on the
Krabby design.
Tentacruel, also known as the ASUS Chromebook CM14 Flip CM1402F, is a
convertible device with touchscreen and stylus.
Tentacool, also known as the ASUS Chromebook CM14 CM1402C, is a laptop
device. It does not have a touchscreen or stylus.
The two devices both have two variants. The difference is a second
source trackpad controller that shares the same address as the original,
but is incompatible.
The extra SKU IDs for the Tentacruel devices map to different sensor
components attached to the Embedded Controller. These are not visible
to the main processor.

MT7988A (AKA MediaTek Filogic 880) is a quad-core ARM Cortex-A73
platform designed for Wi-Fi 7 devices (there is no wireless on SoC
though). The first public MT7988A device is Banana Pi BPI-R4.
Many SoC parts remain to be added (they need their own bindings or
depend on missing clocks). Those present block however are correct and
having base .dtsi will help testing & working on missing stuff.

The pumpkin board is made by Gossamer Engineering and is using
a MediaTek SoC. The board currently comes in two available version:
MT8516 SoC and MT8167 SoC.
The board provides the following IOs: eMMC, NAND, SD card, USB type-A,
Ethernet, Wi-Fi, Bluetooth, Audio (jack out, 2 PDM port, 1 analog in),
serial over USB, HDMI, DSI, CSI, and an expansion header.
The board can be powered by battery and/or via a USB Type-C port and
is using a PMIC MT6392.
The eMMC and NAND are sharing pins and cannot be used together.
This commit is adding the basic boot support for the Pumpkin MT8167
board.

Also known as the Lenovo IdeaPad Duet Chromebook.
There are different krane boards with shared resources, hence a
mt8183-kukui-krane.dtsi was created for easily introduce future new
boards. The same happens with the baseboard codenamed kukui where
different variants, apart from kukui variant can take advantage of the
shared resources.

The pumpkin board is made by Gossamer Engineering and is using
a MediaTek SoC. The board currently comes in two available version:
MT8516 SoC and MT8167 SoC.
The board provides the following IOs: eMMC, NAND, SD card, USB type-A,
Ethernet, Wi-Fi, Bluetooth, Audio (jack out, 2 PDM port, 1 analog in),
serial over USB, and an expansion header.
Additionally there is a HDMI port, DSI port, and camera port only
on the MT8167 version of the board.
The board can be powered by battery and/or via a USB Type-C port and
is using a PMIC MT6392.
The eMMC and NAND are sharing pins and cannot be used together.
This commit is adding the basic boot support for the Pumpkin MT8516
board on the eMMC.

Pull DeviceTree updates from Rob Herring:
"A bigger diffstat than usual with the kbuild changes and a tree wide
fix in the binding documentation.
Summary:
- kbuild cleanups and improvements for dtbs
- Code clean-up of overlay code and fixing for some long standing
memory leak and race condition in applying overlays
- Improvements to DT memory usage making sysfs/kobjects optional and
skipping unflattening of disabled nodes. This is part of kernel
tinification efforts.
- Final piece of removing storing the full path for every DT node.
The prerequisite conversion of printk's to use device_node format
specifier happened in 4.14.
- Sync with current upstream dtc. This brings additional checks to
dtb compiling.
- Binding doc tree wide removal of leading 0s from examples
- RTC binding documentation adding missing devices and some
consolidation of duplicated bindings
- Vendor prefix documentation for nutsboard, Silicon Storage
Technology, shimafuji, Tecon Microprocessor Technologies, DH
electronics GmbH, Opal Kelly, and Next Thing"

If CONFIG_OF_ALL_DTBS is enabled, "make ARCH=arm64 dtbs" compiles each
DTB twice; one from arch/arm64/boot/dts/*/Makefile and the other from
the dtb-$(CONFIG_OF_ALL_DTBS) line in arch/arm64/boot/dts/Makefile.
It could be a race problem when building DTBS in parallel.
Another minor issue is CONFIG_OF_ALL_DTBS covers only *.dts in vendor
sub-directories, so this broke when Broadcom added one more hierarchy
in arch/arm64/boot/dts/broadcom/<soc>/.
One idea to fix the issues in a clean way is to move DTB handling
to Kbuild core scripts. Makefile.dtbinst already recognizes dtb-y
natively, so it should not hurt to do so.
Add $(dtb-y) to extra-y, and $(dtb-) as well if CONFIG_OF_ALL_DTBS is
enabled. All clutter things in Makefiles go away.
As a bonus clean-up, I also removed dts-dirs. Just use subdir-y
directly to traverse sub-directories.
