79ed18d9ec arm64: tegra: Sort nodes by unit-address, then alphabetically
Nodes in device tree should be sorted by unit-address, followed by nodes
without a unit-address, sorted alphabetically. Some exceptions are the
top-level aliases, chosen, firmware, memory and reserved-memory nodes,
which are expected to come first.

These rules apply recursively with some exceptions, such as pinmux nodes
or regulator nodes, which often follow more complicated ordering (often
by "importance").

While at it, change the name of some of the nodes to follow standard
naming conventions, which helps with the sorting order and reduces the
amount of warnings from the DT validation tools.

2838cfddbc arm64: tegra: Bump #address-cells and #size-cells
The #address-cells and #size-cells properties for the top-level bus were
set to 1 because that was enough to represent the register ranges of all
the IP blocks on that bus. However, most of these devices can do DMA to
a larger address space, so translation of DMA addresses needs to happen
in a 64-bit address space.

Partially this was already done by the memory controller increasing that
address space by setting #address-cells and #size-cells to 2, but a full
DMA address translation would still cause truncation when traversing to
the top-level bus.

Fix this by setting #address-cells = <2> and #size-cells = <2> on the
top-level bus and adjusting all "reg" and "ranges" properties of its
children.

While at it, also move the PCI and GPU nodes back under the top-level
bus where they belong. The were put outside of it to work around this
same problem.

Syzkaller detected a memory leak of skbs in ath9k_hif_usb_rx_stream().
While processing skbs in ath9k_hif_usb_rx_stream(), the already allocated
skbs in skb_pool are not freed if ath9k_hif_usb_rx_stream() fails. If we
have an incorrect pkt_len or pkt_tag, the input skb is considered invalid
and dropped. All the associated packets already in skb_pool should be
dropped and freed. Added a comment describing this issue.

The patch also makes remain_skb NULL after being processed so that it
cannot be referenced after potential free. The initialization of hif_dev
fields which are associated with remain_skb (rx_remain_len,
rx_transfer_len and rx_pad_len) is moved after a new remain_skb is
allocated.

28a35ac2f5 ACPI: PNP: Introduce list of known non-PNP devices
In some cases, PNP device IDs from acpi_pnp_device_ids[] are returned by
_CID for devices for which matching platform drivers are present in the
kernel and should be bound to them.  However, the IDs coming from _CID
cause the PNP scan handler to attach to those devices which prevents
platform device objects from being created for them.

Address this by introducing a list of known non-PNP device IDs into
acpi_pnp.c such that if a device ID is there in that list, it cannot be
attached to by the PNP scan handler and add the platform runtime update
and telemetry device IDs to that list to start with.

21cbd90a6f inet: fix fast path in __inet_hash_connect()
__inet_hash_connect() has a fast path taken if sk_head(&tb->owners) is
equal to the sk parameter.
sk_head() returns the hlist_entry() with respect to the sk_node field.
However entries in the tb->owners list are inserted with respect to the
sk_bind_node field with sk_add_bind_node().
Thus the check would never pass and the fast path never execute.

This fast path has never been executed or tested as this bug seems
to be present since commit 1da177e4c3 ("Linux-2.6.12-rc2"), thus
remove it to reduce code complexity.

cddf70d0bc i2c: dev: fix notifier return values
We have a set of return values that notifier callbacks can return. They
should not return 0, error codes or anything other than those predefined
values. Make the i2c character device's callback return NOTIFY_DONE or
NOTIFY_OK depending on the situation.

6ce3563520 thunderbolt: Add support for DisplayPort bandwidth allocation mode
The USB4 spec defines an optional feature that allows the connection
manager to negotiate with the graphics through DPCD registers changes in
the bandwidth allocation dynamically. This is referred as "bandwidth
allocation mode" in the spec. The connection manager uses DP IN adapters
registers to communicate with the graphics, and also gets notifications
from these adapters when the graphics wants to change the bandwidth
allocation. Both the connection manager and the graphics driver needs to
support this.

We check if the DP IN adapter supports this and if it does enable it
before establishing a DP tunnel. Then we react on DP_BW notifications
coming from the DP IN adapter and update the bandwidth allocation
accordingly (within the maximum common capabilities the DP IN/OUT
support).

630f211be7 thunderbolt: Include the additional DP IN double word in debugfs dump
When DisplayPort bandwidth allocation mode is supported by the DP IN
adapter it has an extra double word in the adapter config space. Include
this in the debugfs register dump.

e327380133 thunderbolt: Add functions to support DisplayPort bandwidth allocation mode
USB4 spec defines an additional feature that DP IN adapters can
implement (alongside with the graphics DPCD register set) to support
more dynamic bandwidth management for DisplayPort tunnels. For the
connection manager the communication happens through the DP IN adapter
using a set of registers in the adapter config space allocated for this.
Add functions that export this functionality for the rest of the driver.

e70a8f3698 thunderbolt: Take CL states into account when waiting for link to come up
If CL states are enabled for the link it may be in these states too when
reading the lane adapter state but it will enter CL0 as soon as there is
traffic in the high-speed lanes. Upon discovery we want to make sure
that is accounted as the link being up, otherwise we end up tearing down
the topology with no good reason.

1cea99593c thermal/drivers/imx_sc_thermal: Add iMX8QM sensors
Add iMX8QM sensors. As stated in 31fd4b9db1 ("thermal/drivers/imx_sc:
Rely on the platform data to get the resource id"):

    The thermal OF code returns -ENODEV if the thermal zone registration
    with a specific id fails because the description is not available in
    the DT for such a sensor id. In this case we continue with the other
    ids without bailing out with an error.
