Josua Mayer requested to have OF nodes for each lane, so that he
(and other board developers) can further describe electrical parameters
individually.
For this use case, we need a container node to apply the already
existing Documentation/devicetree/bindings/phy/transmit-amplitude.yaml,
plus whatever other schemas might get standardized for TX equalization
parameters, polarity inversion etc.
When lane OF nodes exist, these are also PHY providers ("phys" phandles
can point directly to them). Compare that to the existing binding, where
the PHY provider is the top-level SerDes node, and the second cell in
the "phys" phandle specifies the lane index.
The new binding format overlaps over the old one without interfering,
but there is a caveat:
Existing device trees, which already have "phys = <&serdes1 0>" cannot
be converted to "phys = <&serdes_1_lane_a>", because in doing so, we
would break compatibility with old kernels which don't understand how to
translate the latter phandle to a PHY.
The transition to the new phandle format can be performed only after a
reasonable amount of time has elapsed after this schema change and the
corresponding driver change have been backported to stable kernels.
However, the aforementioned transition is not strictly necessary, and
the "hybrid" description (where individual lanes have their own OF node,
but are not pointed to by the "phys" phandle) can remain for an
indefinite amount of time, even if a little inelegant.
For newly introduced device trees, where there are no compatibility
concerns with old kernels to speak of, it is strongly recommended to use
the "phys = <&serdes_1_lane_a>" format. The same holds for phandles
towards lanes of LX2160A SerDes #3, which at the time of writing is not
yet described in fsl-lx2160a.dtsi, so there is no legacy to maintain.
To avoid the strange situation where we have a "phy" (SerDes node) ->
"phy" (lane node) hierarchy, let's rename the expected name of the
top-level node to "serdes", and update the example too. This has a
theoretical chance of causing regressions if bootloaders search for
hardcoded paths rather than using aliases, but to the best of my
knowledge, for LX2160A/LX2162A this is not the case.

The Tensor G5 silicon represents a complete architectural departure from

existing Samsung/Exynos DWC3 USB bindings are incompatible, necessitating
this new device tree binding.

- Update ADMA device tree bindings for tegra264 to support up to 64
interrupt channels by setting 'interrupts' property maxItems to 64.
- Also, update the 'allOf' conditional schema to ensure correct maxItems
for 'interrupts' based on compatible string, including tegra210 (22)
and tegra186 (32) ADMA controllers.

Add support for the APDMA IP found in all of the SoC generations
that are currently supported upstream; this includes:
- MT8173, MT8183, fully compatible with MT6577 (32-bits)
- MT7988, MT8186, MT8188, MT8192, MT8195 and MT6835 (34-bits)
- MT6991, MT8196 and MT6985 (35-bits)
...where:
- MT6835 is the first SoC where the AP_DMA IP supports 34-bits
addressing; and
- MT6985 is the first SoC where the AP_DMA IP supports 35-bits
addressing.
While at it, also add myself in the maintainers list.

While this property wants to express a capability of the hardware,
this is only used by the driver itself to vary the DMA bits during
probe.
Different hardware shall instead have different compatible strings.
Following the driver cleanup and the introduction of a specific
compatible string for the APDMA IP version found in MT6795, set
the "mediatek,dma-33bits" vendor property as deprecated.

While it is true that this SoC is compatible with the MT6577 APDMA
IP, that is valid only when the IP is used in 32-bits addressing
mode, and, by the way there is no good reason to do so.
Since the APDMA IP in MT6795 supports 33 bits addressing, this
means that it is a newer revision compared to the one found in
MT6577, hence only partially compatible with it.
Allow nodes to specify "mediatek,mt6795-uart-dma" as their only
compatible in the case of MT6795; this is done in lieu of the fact
that there are other SoCs integrating the same version of this IP
as MT6795, and those will eventually get their own compatible that
expresses full compatibility with this SoC.

The SpacemiT K3 UART controller is compatible with the Intel XScale UART.
Add K3 UART binding and allow describing it with a fixed clock-frequency
for now.
The clocks and clock-names properties will be made mandatory in a future
patch, once the K3 clock driver and device tree are merged.

Some thoughts on hardware that is used for real-time workload. Certainly
not complete but should cover some of the import topics such as:
- Main memory, caches and the possiblie control given by the hardware.
- What could happen by putting critical hardware behind USB or VirtIO.
- Allowing real-time tasks to consume the CPU entirely without giving
the system some time to breath.
- Networking with what the kernel provides.

For several years, and still ongoing, the kernel.h is being split
to smaller and narrow headers to avoid "including everything" approach
which is bad in many ways. Since that, documentation missed a few
required updates to align with that work. Do it here.
Note, language translations are left untouched and if anybody willing
to help, please provide path(es) based on the updated English variant.

Don't claim that /dev/sr<N> device names for SCSI CD-ROM drives are
deprecated and don't recommend /dev/scd<N> alternate names for them.
/dev/scd<N> device names for SCSI CD-ROM drives are not in use for more
than a decade, see commit [1] that was a part of udev release 174.
Earlier, related rules were volatile, sometimes /dev/scd<N> were syminks
to /dev/sr<N>, sometimes vice versa.
Recognizing of root=/dev/scd<N> kernel command line argument was removed
in kernel 2.5.45 [2].
In the docs /dev/scd<N> became recommended names in 2.6.9 [3].
Mention of these names appeared much earlier in 1.3.22 [4].
