The examples template is a 'simple-bus' with a size of 1 cell for
had between 2 and 4 cells which really only errors on I2C or SPI type
devices with a single cell.
The easiest fix in most cases is to change the 'reg' property to for 1 cell
address and size. In some cases with child devices having 2 cells, that
doesn't make sense so a bus node is needed.

The 'reg' description and example have a 2nd register region for memory

json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords. The json-schema library doesn't yet support this, but the
tooling now does a fixup for this and either way works.
This has been a constant source of review comments, so let's change this
treewide so everyone copies the simpler syntax.
Scripted with ruamel.yaml with some manual fixups. Some minor whitespace
changes from the script.

Fix various inconsistencies in schema indentation. Most of these are
list indentation which should be 2 spaces more than the start of the
enclosing keyword. This doesn't matter functionally, but affects running
scripts which do transforms on the schema files.

The descriptions for the spi-rx-bus-width and spi-tx-bus-width
properties refer to "MISO" and "MOSI", which are not explained in the
document. While these abbreviations are fairly common when talking
about SPI, and thus may not need an explanation, they are not entirely
correct in this context, as the SPI controller may be used in slave mode
instead of master mode.
Fix this by replacing them by "read transfers" resp. "write transfers",
like is done for the spi-rx-delay-us and spi-tx-delay-us properties.

Currently, the DT bindings for an SPI controller specify that
"#address-cells" must be fixed to one. However, that applies to an SPI
controller in master mode only. When running in SPI slave mode,
"#address-cells" should not be specified.
Fix this making "#address-cells" mutually-exclusive with "spi-slave".

spi: Rewrite mtk-quadspi spi-nor driver with spi-mem
This patchset from Chuanhong Guo <gch981213@gmail.com> adds a spi-mem
driver for Mediatek SPI-NOR controller, which already has limited
support by mtk-quadspi. This new driver can make use of full quadspi
capability of this controller.
spi-mtk-nor is a driver to replace mtk-quadspi and they have almost
the same device-tree bindings. Reuse this binding documentation and
convert it for new driver:
1. "Mediatek SoCs" -> "Mediatek ARM SoCs" because MTK MIPS SoCs
use different controllers.
2. document "interrupts" as a required property because it's
available on all SoCs with this controller and new driver takes
advantages of it. It's implemented as optional only to maintain
backward compatibility.
3. add a dummy interrupt binding in example.

This series makes room in the driver for differentiation between the
controllers which currently operate in TCFQ mode. Most of these are
actually capable of a lot more in terms of throughput. This is in
preparation of a second series which will convert the remaining users of
TCFQ mode altogether to XSPI mode with command cycling.

Make the second compatible string optional for LS1012A, LS1088A and
LS2080A. Old versions of the spi-fsl-dspi.c driver still need to probe
on the old, generic compatible string for these controllers (such as
"fsl,ls1021a-v1.0-dspi") which provides less functionality.
Document the device tree bindings for LS1043A and LS1046A, whose
bindings are already in use in fsl-ls1043a.dtsi and fsl-ls1046a.dtsi.
Introduce new compatible strings for LS1028A and LX2160A. There will be
no second compatible string for these.

There are several DT doc references that require manual fixes.
I found 3 cases fixed on this patch:
- directory named "binding/" instead of "bindings/";
- .txt to .yaml renames;

The Renesas RZ/N1 SPI Controller is based on the Synopsys DW SSI, but has
additional registers for software CS control and DMA. This patch does not
address the changes required for DMA support, it simply adds the compatible
string. The CS functionality is not very useful and also not needed as
Linux can use gpios for the CS signals.
Add a compatible string to handle any unforeseen issues that may arise, and
pave the way for DMA support.

This is another huge branch with close to 450 changessets related to
devicetree files, roughly half of this for 32-bit and 64-bit respectively.
There are lots of cleanups and additional hardware support for platforms
we already support based on SoCs from Renesas, ST-Microelectronics,
Intel/Altera, Rockchips, Allwinner, Broadcom and other manufacturers.
A total of 6 new SoCs and 37 new boards gets added this time, one more
SoC will come in a follow-up branch. Most of the new boards are for
64-bit ARM SoCs, the others are typically for the 32-bit Cortex-A7.
Going more into details for SoC platforms with new hardware support:
The Snapdragon 855 (SM8150) is Qualcomm's current high-end phone platform,
usually paired with an external 5G modem. So far we only support the
Qualcomm SM8150 MTP reference platform, but no actual products.
For the slightly older Qualcomm platforms, support for several interesting
products is getting added: Three laptops based on Snapdragon 835/MSM8998
(Asus NovaGo, HP Envy X2 and Lenovo Miix 630), one laptop based on
Snapdragon 850/sdm850 (Lenovo Yoga C630) and several phones based on
the older Snapdragon 410/MSM8916 (Samsung A3 and A5, Longcheer L8150
aka Android One 2nd gen "seed" aka Wileyfox Swift).
Mediatek MT7629 is a new wireless network router chip, similar to
the older MT7623. It gets added together with the reference board
implementation.
Allwinner V3 is a repackaged version of the existing low-end V3s chip,
and is used in the tiny Lichee Pi Zero plus, also added here. There is
also a new TV set-top box based on Allwinner H6, the Tanix TX6, and the
eMMC variant of the Olimex A64-Olinuxino development board.
NXP i.MX8M Nano is a new member of the ever-expanding i.MX SoC family,
similar to the i.MX8M Mini. As usual, there is a large number of new
boards for i.MX SoCs: Einfochips i.MX8QXP AI_ML, SolidRun Hummingboard
Pulse baseboard and System-on-Module, Boundary Devices i.MX8MQ Nitrogen8M,
and TechNexion PICO-PI-IMX8M-DEV for the 64-bit i.MX8 line. For 32-bit,
we get the Kontron i.MX6UL N6310 SoM with two baseboards, the PHYTEC
phyBOARD-Segin SoM with three baseboards, and the Zodiac Inflight
Innovations i.MX7 RMU2 board.
In a different NXP product line, the Layerscape LS1046A "Freeway"
reference board gets added.
Amlogic SM1 (S905X3) and G12B (S922X, A311D) are updated chips from their
set-top-box line and smart speaker with newer CPU and GPU cores compared
to their predecessors. Both are now also supported by the Khadas VIM3
development board series, and the dts files for that get reorganized a
bit to better deal with all variants. Another board based on SM1 that
gets added is the SEI Robotics SEI610.
There are a handful of new x86 and Power9 server boards using Aspeed BMC
chips that are gaining support for running Linux on the BMC through the
OpenBMC project: Facebook Minipack/Wedge100/Wedge40, Lenovo Hr855xg2,
and Mihawk. Notably these are still new machines using SoCs based on
the ARM9 and ARM11 CPU cores, as support for the new Cortex-A7 based
AST2600 is still ramping up.
There are three new end-user products using 32-bit Rockchips SoCs:
Mecer Xtreme Mini S6 is an Android "mini PC" box based on the low-end
RK3229 chip, while the two AOpen products Chromebox Mini (Fievel) and
Chromebase Mini (Tiger) run ChromeOS and are meant for commercial settings
(digital signage, PoS, ...).
One more single-board computer based on the popular 64-bit RK3399 is
added: the Leez RK3399 P710.

support the Qualcomm SM8150 MTP reference platform, but no actual
products.
- For the slightly older Qualcomm platforms, support for several
interesting products is getting added: Three laptops based on
Snapdragon 835/MSM8998 (Asus NovaGo, HP Envy X2 and Lenovo Miix
630), one laptop based on Snapdragon 850/sdm850 (Lenovo Yoga C630)
and several phones based on the older Snapdragon 410/MSM8916
(Samsung A3 and A5, Longcheer L8150 aka Android One 2nd gen "seed"
aka Wileyfox Swift).
- Mediatek MT7629 is a new wireless network router chip, similar to
the older MT7623. It gets added together with the reference board
implementation.
- Allwinner V3 is a repackaged version of the existing low-end V3s
chip, and is used in the tiny Lichee Pi Zero plus, also added here.
There is also a new TV set-top box based on Allwinner H6, the Tanix
TX6, and the eMMC variant of the Olimex A64-Olinuxino development
board.
- NXP i.MX8M Nano is a new member of the ever-expanding i.MX SoC
family, similar to the i.MX8M Mini. As usual, there is a large
number of new boards for i.MX SoCs: Einfochips i.MX8QXP AI_ML,
SolidRun Hummingboard Pulse baseboard and System-on-Module,
Boundary Devices i.MX8MQ Nitrogen8M, and TechNexion
PICO-PI-IMX8M-DEV for the 64-bit i.MX8 line. For 32-bit, we get the
Kontron i.MX6UL N6310 SoM with two baseboards, the PHYTEC
phyBOARD-Segin SoM with three baseboards, and the Zodiac Inflight
Innovations i.MX7 RMU2 board.
- In a different NXP product line, the Layerscape LS1046A "Freeway"
reference board gets added.
- Amlogic SM1 (S905X3) and G12B (S922X, A311D) are updated chips from
their set-top-box line and smart speaker with newer CPU and GPU
cores compared to their predecessors. Both are now also supported
by the Khadas VIM3 development board series, and the dts files for
that get reorganized a bit to better deal with all variants.
Another board based on SM1 that gets added is the SEI Robotics
SEI610.
- There are a handful of new x86 and Power9 server boards using
Aspeed BMC chips that are gaining support for running Linux on the
BMC through the OpenBMC project: Facebook
Minipack/Wedge100/Wedge40, Lenovo Hr855xg2, and Mihawk. Notably
these are still new machines using SoCs based on the ARM9 and ARM11
CPU cores, as support for the new Cortex-A7 based AST2600 is still
ramping up.
- There are three new end-user products using 32-bit Rockchips SoCs:
Mecer Xtreme Mini S6 is an Android "mini PC" box based on the
low-end RK3229 chip, while the two AOpen products Chromebox Mini
(Fievel) and Chromebase Mini (Tiger) run ChromeOS and are meant for
commercial settings(digital signage, PoS, ...).
- One more single-board computer based on the popular 64-bit RK3399
is added: the Leez RK3399 P710"
