The concept of timestamping DSA switches / Ethernet PHYs is becoming
more and more popular, however the Linux kernel timestamping code has
evolved quite organically and there's layers upon layers of new and old
code that need to work together for things to behave as expected.
Add this chapter to explain what the overall goals are.
Loosely based upon this email discussion plus some more info:

There are no non-standard bindings being used. However Felix is a PCI
device and Seville is a platform device. So give an example of device
tree for this switch and document its compatible string.

Add an interface to report offloaded UDP ports via ethtool netlink.
Now that core takes care of tracking which UDP tunnel ports the NICs
are aware of we can quite easily export this information out to
user space.
The responsibility of writing the netlink dumps is split between
ethtool code and udp_tunnel_nic.c - since udp_tunnel module may
not always be loaded, yet we should always report the capabilities
of the NIC.
$ ethtool --show-tunnels eth0
Tunnel information for eth0:
UDP port table 0:
Size: 4
Types: vxlan
No entries
UDP port table 1:
Size: 4
Types: geneve, vxlan-gpe
Entries (1):
port 1230, vxlan-gpe
v4:
- back to v2, build fix is now directly in udp_tunnel.h
v3:
- don't compile ETHTOOL_MSG_TUNNEL_INFO_GET in if CONFIG_INET
not set.
v2:
- fix string set count,
- reorder enums in the uAPI,
- fix type of ETHTOOL_A_TUNNEL_UDP_TABLE_TYPES to bitset
in docs and comments.

debugfs_create_u32_array() allocates a small structure to wrap
the data and size information about the array. If users ever
try to remove the file this leads to a leak since nothing ever
frees this wrapper.
That said there are no upstream users of debugfs_create_u32_array()
that'd remove a u32 array file (we only have one u32 array user in
CMA), so there is no real bug here.
Make callers pass a wrapper they allocated. This way the lifetime
management of the wrapper is on the caller, and we can avoid the
potential leak in debugfs.

Implement a managed variant of of_mdiobus_register(). We need to make
mdio_devres into its own module because otherwise we'd hit circular
sumbol dependencies between phylib and of_mdio.

We currently have two managed helpers for mdiobus - devm_mdiobus_alloc()
and devm_mdiobus_register(). The idea behind devres is that the release
callback releases whatever resource the devm function allocates. In the
mdiobus case however there's no devres associated with the device by
devm_mdiobus_register(). Instead the release callback for
devm_mdiobus_alloc(): _devm_mdiobus_free() unregisters the device if
it is marked as managed.
This all seems wrong. The managed structure shouldn't need to know or
care about whether it's managed or not - and this is the case now for
struct mii_bus. The devres wrapper should be opaque to the managed
resource.
This changeset makes devm_mdiobus_alloc() and devm_mdiobus_register()
conform to common devres standards: devm_mdiobus_alloc() allocates a
devres structure and registers a callback that will call mdiobus_free().
__devm_mdiobus_register() allocated another devres and registers a
callback that will unregister the bus.

We have a devres variant of mdiobus_register() but it's not listed in
devres.rst. Add it under other mdio devm functions.

There are two processed schema files:
- processed-schema-examples.yaml
Used for 'make dt_binding_check'. This is always a full schema.
- processed-schema.yaml
Used for 'make dtbs_check'. This may be a full schema, or a smaller
subset if DT_SCHEMA_FILES is given by a user.
If DT_SCHEMA_FILES is not specified, they are the same. You can copy
the former to the latter instead of running dt-mk-schema twice. This
saves the cpu time a lot when you do 'make dt_binding_check dtbs_check'
because building the full schema takes a couple of seconds.
If DT_SCHEMA_FILES is specified, processed-schema.yaml is generated
based on the specified yaml files.

Currently, processed-schema.yaml is always built, but it is actually
used only for 'make dtbs_check'.
'make dt_binding_check' uses processed-schema-example.yaml instead.

We are having more and more schema files.
Commit 8b6b80218b01 ("dt-bindings: Fix command line length limit
calling dt-mk-schema") fixed the 'Argument list too long' error of
the schema checks, but the same error happens while cleaning too.
'make clean' after 'make dt_binding_check' fails as follows:
$ make dt_binding_check
[ snip ]
$ make clean
make[2]: execvp: /bin/sh: Argument list too long
make[2]: *** [scripts/Makefile.clean:52: __clean] Error 127
make[1]: *** [scripts/Makefile.clean:66: Documentation/devicetree/bindings] Error 2
make: *** [Makefile:1763: _clean_Documentation] Error 2
'make dt_binding_check' generates so many .example.dts, .dt.yaml files,
which are passed to the 'rm' command when you run 'make clean'.
I added a small hack to use the 'find' command to clean up most of the
build artifacts before they are processed by scripts/Makefile.clean
