USB4 spec specifies standard set of sideband operations that are send
over the low speed link to access either retimers on the link or the
link parter (the other router). The USB4 retimer spec extends these and
adds operations for retimer NVM upgrade.
This implements the retimer access and NVM upgrade USB4 port sideband
operations which we need for retimer support in the patch that follows.

Especially when accessing retimers over USB4 sideband operations the
possibility to get read errors seems to be higher so make the
usb4_do_read_data() retry a couple of times if it sees any other error
than -ENODEV (device is gone). We can only do this for read side because
it carries the offset as part of metadata (as opposed to writes).

Currently these functions operate on struct tb_switch but we are going
to need the same functionality with retimers as well so make the two
functions work with an arbitrary object that gets passed as parameter to
the callbacks.

We are going to reuse some of this functionality to implement retimer
NVM upgrade so move common NVM functionality into its own file. We also
rename the structure from tb_switch_nvm to tb_nvm to make it clear that
it is not just for switches.

With USB4 Intel is also using its USB-IF ID (0x8087) with the new
devices. The NVM format is the same. Add this to the driver so NVM
upgrade is possible with these devices as well.

USB3 supports both isochronous and non-isochronous traffic. The former
requires guaranteed bandwidth and can take up to 90% of the total
bandwidth. With USB4 USB3 is tunneled over USB4 fabric which means that
we need to make sure there is enough bandwidth allocated for the USB3
tunnels in addition to DisplayPort tunnels.
Whereas DisplayPort bandwidth management is static and done before the
DP tunnel is established, the USB3 bandwidth management is dynamic and
allows increasing and decreasing the allocated bandwidth according to
what is currently consumed. This is done through host router USB3
downstream adapter registers.
This adds USB3 bandwidth management to the software connection manager
so that we always try to allocate maximum bandwidth for DP tunnels and
what is left is allocated for USB3.

We need to call this from tb.c when we improve the bandwidth management

Each host router USB3 downstream adapter has a set of registers that are
used to negotiate bandwidth between the connection manager and the
internal xHCI controller. These registers allow dynamic bandwidth
management for USB3 isochronous traffic based on what is actually
consumed vs. allocated at any given time.
Implement these USB3 bandwidth negotiation routines to allow the
software connection manager take advantage of these.

Sometimes it takes longer for DPRX to be set so increase the timeout to

Whereas DisplayPort bandwidth is consumed only in one direction (from DP
IN adapter to DP OUT adapter), USB3 adds separate bandwidth for both
upstream and downstream directions.
For this reason extend the tunnel consumed bandwidth routines to support
both directions and implement this for DP.

USB3 tunneling is possible only over USB4 link so don't create USB3
tunnels if that's not the case.
Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>

USB4 spec allows DP tunneling from any router that has DP IN adapter,
not just from host router. The driver currently only added the DP IN
resources for the host router because Thunderbolt 1, 2 and 3 devices do
not have DP IN adapters. However, USB4 allows device routers to have DP
IN adapter as well so update the driver to add DP IN resources for each
device that has one. One example would be an eGPU enclosure where the
eGPU output is forwarded to DP IN port and then tunneled over the USB4
fabric.
Only limitation we add now is that the DP IN and DP OUT that gets paired
for tunnel creation should both be under the same topology starting from
host router downstream port. In other words we do not create DP tunnels
across host router at this time even though that is possible as well but
it complicates the bandwidth management and there is no real use-case
for this anyway.

This adds KUnit tests for path walking which is only dependent on
software structures, so no hardware is needed to run these.
We make these available only when both KUnit and the driver itself are
built into the kernel image. The reason for this is that KUnit adds its
own module_init() call in kunit_test_suite() which generates linker
error because the driver does the same in nhi.c. This should be fine for
now because these tests are only meant to run by developers anyway.

Currently we have only supported paths that follow daisy-chain topology
but USB4 also allows to build trees of devices. For this reason increase
maximum path length we use for discovery to be from the lowest level to
the host router and back to the same level.
Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>

If the path is not complete when we do discovery the number of hops may
be less than with the full path. As an example when this can happen is
that user unloads the driver, disconnects the topology, and loads the
driver back. If there is PCIe or USB3 tunnel involved this may happen.
Take this into account in tb_pcie_init_path() and tb_usb3_init_path()
and prevent potential access over array limits.

With USB4, topologies are not limited to daisy-chains anymore so when
calculating how many hops are between two ports we need to walk the
whole path instead.
Add helper function tb_for_each_port_on_path() that can be used to walk
over each port on a path and make tb_path_alloc() to use it.

USB4 makes it possible to have tree topology of devices connected in the
same way than USB3. This was actually possible in Thunderbolt 1, 2 and 3
as well but all the available devices only had two ports which allows
building only daisy-chains of devices.
With USB4 it is possible for example that there is DP IN adapter as part
of eGPU device router and that should be tunneled over the tree topology
to a DP OUT adapter. This updates the tb_next_port_on_path() to support
such topologies.

The USB3 discovery used wrong indices when tunnel is discovered. It
should use TB_USB3_PATH_DOWN for path that flows downstream and
TB_USB3_PATH_UP when it flows upstream. This should not affect the
functionality but better to fix it.

The end-to-end (E2E) workaround is needed for Falcon Ridge (TBT 2)
controller when E2E is enabled for both ends of the host-to-host
connection. However, we never supported full E2E in the first place so
this code is not necessary at the moment. Further this allows us to use
all available rings for data except ring 0 which is reserved for the
control path.
The complete E2E flow control is explained in the USB4 spec so we may
add it back later if needed but at least the networking driver seems to
work fine without, and the higher level stack, like TCP will retransmit
lost packets anyway.

On a systems where the Thunderbolt controller is present all the time
the kernel nodename may not yet set by the userspace when the driver is
loaded. This means when another host is connected it may see the default
"(none)" hostname instead of the system real hostname.
For this reason build the initial XDomain property block only upon first
connect. This should make sure the userspace has had chance to set it up.

This reverts commit a43a67a2d715540c1368b9501a22b0373b5874c0.
This patch reverts the main part of switching direct io implementation
to iomap infrastructure. There's a problem in invalidate page that
couldn't be solved as regression in this development cycle.
The problem occurs when buffered and direct io are mixed, and the ranges
overlap. Although this is not recommended, filesystems implement
measures or fallbacks to make it somehow work. In this case, fallback to
buffered IO would be an option for btrfs (this already happens when
direct io is done on compressed data), but the change would be needed in
the iomap code, bringing new semantics to other filesystems.
Another problem arises when again the buffered and direct ios are mixed,
invalidation fails, then -EIO is set on the mapping and fsync will fail,
though there's no real error.
There have been discussions how to fix that, but revert seems to be the
least intrusive option.

On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow
unregistered mcast packets to pass.
This happens, because ALE VLAN entries on these SoCs do not contain port
masks for reg/unreg mcast packets, but instead store indexes of
ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for
reg/unreg mcast packets.
This path was missed by commit 9d1f6447274f ("net: ethernet: ti: ale: fix
seeing unreg mcast packets with promisc and allmulti disabled").
Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti().
