arm64: dts: rockchip: move QCA6174A wakeup pin into its USB node
Currently, we don't coordinate BT USB activity with our handling of the
BT out-of-band wake pin, and instead just use gpio-keys. That causes
problems because we have no way of distinguishing wake activity due to a
BT device (e.g., mouse) vs. the BT controller (e.g., re-configuring wake
mask before suspend). This can cause spurious wake events just because
we, for instance, try to reconfigure the host controller's event mask
before suspending.
We can avoid these synchronization problems by handling the BT wake pin
directly in the btusb driver -- for all activity up until BT controller
suspend(), we simply listen to normal USB activity (e.g., to know the
difference between device and host activity); once we're really ready to
suspend the host controller, there should be no more host activity, and
only *then* do we unmask the GPIO interrupt.
This is already supported by btusb; we just need to describe the wake
pin in the right node.
We list 2 compatible properties, since both PID/VID pairs show up on
Scarlet devices, and they're both essentially identical QCA6174A-based
modules.
Also note that the polarity was wrong before: Qualcomm implemented WAKE
as active high, not active low. We only got away with this because
gpio-keys always reconfigured us as bi-directional edge-triggered.
Finally, we have an external pull-up and a level-shifter on this line
(we didn't notice Qualcomm's polarity in the initial design), so we
can't do pull-down. Switch to pull-none.

- Fixed a scaling issue when adding more auto-tuning cases which caused

This series contains updates to the ice driver only.
Bruce adds the __always_unused attribute to a parameter to avoid
compiler warnings when using -Wunused-parameter. Fixed unnecessary
type-casting and the use of sizeof(). Fix the allocation of structs
that have become memory hogs, so allocate them in heaps and fix all the
associated references. Fixed the "possible" numeric overflow issues
that were caught with static analysis.
Maciej fixes the maximum MTU calculation by taking into account double
VLAN tagging amd ensure that the operations are done in the correct
order.
Victor fixes the supported node calculation, where we were not taking
into account if there is space to add the new VSI or intermediate node
above that layer, then it is not required to continue the calculation.
Added a check for a leaf node presence for a given VSI, which is needed
before removing a VSI.
Jake fixes an issue where the VSI list is shared, so simply removing a
VSI from the list will cause issues for the other users who reference
the list. Since we also free the memory, this could lead to
segmentation faults.
Brett fixes an issue where driver unload could cause a system reboot
when intel_iommu=on parameter is set. The issue is that we are not
clearing the CAUSE_ENA bit for the appropriate control queues register
when freeing the miscellaneous interrupt vector.
Mitch is so kind, he prevented spamming the VF with link messages when
the link status really has not changed. Updates the driver to use the
absolute vector ID and not the per-PF vector ID for the VF MSIx vector
allocation.
Lukasz fixes the ethtool pause parameter for the ice driver, which was
originally based off the link status but is now based off the PHY
configuration. This is to resolve an issue where pause parameters could
be set while link was down.
Jesse updates the string that reports statistics so the string does not
get modified at runtime and cause reports of string truncation.

Function tc_dump_chain() obtains and releases block->lock on each iteration

ice: fix issue where host reboots on unload when iommu=on
Currently if the kernel has the intel_iommu=on parameter set, on some
platforms removing the driver causes a system reboot. In initialization
we associate the control queue interrupts with the pf->hw_oicr_idx and
enable the interrupts by setting the CAUSE_ENA bit. The problem comes
on teardown because we are not clearing the CAUSE_ENA bit for the
control queues, but the vector at pf->hw_oicr_idx (miscellaneous
interrupt vector) gets disabled.
Fix this by clearing the CAUSE_ENA bit in the appropriate control queue
registers on when freeing the miscellaneous interrupt vector. Also,
move the call to ice_free_irq_msix_misc() to after ice_deinit_sw() in
ice_remove() because ice_deinit_sw() makes an AQ call, but
ice_free_irq_msix_misc() disables the miscellaneous vector and it's

Also, create two small helper functions to enable and disable the

ice: fix ice_remove_rule_internal vsi_list handling
When adding multiple VLANs to the same VSI, the ice_add_vlan code will
share the VSI list, so as not to create multiple unnecessary VSI lists.
Consider the following flow
ice_add_vlan(hw, <VSI 0 VID 7, VSI 0 VID 8, VSI 0 VID 9>)
Where we add three VLAN filters for VIDs 7, 8, and 9, all for VSI 0.
The ice_add_vlan will create a single vsi_list and share it among all
the filters.
Later, if we try to remove a VLAN,
ice_remove_vlan(hw, <VSI 0 VID 7>)
Then the removal code will update the vsi_list and remove VSI 0 from it.
But, since the vsi_list is shared, this breaks the list for the other
users who reference it. We actually even free the VSI list memory, and
may result in segmentation faults.
This is due to the way that VLAN rule share VSI lists with reference
counts, and is caused because we call ice_rem_update_vsi_list even when
the ref_cnt is greater than one.
To fix this, handle the case where ref_cnt is greater than one
separately. In this case, we need to remove the associated rule without
modifying the vsi_list, since it is currently being referenced by
another rule. Instead, we just need to decrement the VSI list ref_cnt.
The case for handling sharing of VSI lists with multiple VSIs is not
currently supported by this code. No such rules will be created today,
and this code will require changes if/when such code is added.

Possible unsafe locking scenario:

lock(&desc->request_mutex);
lock(&chip->reg_lock);
lock(&desc->request_mutex);
lock(&chip->reg_lock);
&desc->request_mutex refer to two different mutex. #1 is the GPIO for
the chip interrupt. #2 is the chained interrupt between global 1 and
global 2.
Add lockdep classes to the GPIO interrupt to avoid this.

tls: Return type of non-data records retrieved using MSG_PEEK in recvmsg
The patch enables returning 'type' in msghdr for records that are
retrieved with MSG_PEEK in recvmsg. Further it prevents records peeked
from socket from getting clubbed with any other record of different
type when records are subsequently dequeued from strparser.
For each record, we now retain its type in sk_buff's control buffer
cb[]. Inside control buffer, record's full length and offset are already
stored by strparser in 'struct strp_msg'. We store record type after
'struct strp_msg' inside 'struct tls_msg'. For tls1.2, the type is
stored just after record dequeue. For tls1.3, the type is stored after
record has been decrypted.
Inside process_rx_list(), before processing a non-data record, we check
that we must be able to return back the record type to the user
application. If not, the decrypted records in tls context's rx_list is
left there without consuming any data.

mlxsw: spectrum_acl: Don't take rtnl mutex for region rehash
Jiri says:
During region rehash, a new region is created with a more optimized set
of masks (ERPs). When transitioning to the new region, all the rules
from the old region are copied one-by-one to the new region. This
transition can be time consuming and currently done under RTNL lock.
In order to remove RTNL lock dependency during region rehash, introduce
multiple smaller locks guarding dedicated structures or parts of them.
That is the vast majority of this patchset. Only patch #1 is simple
cleanup and patches 12-15 are improving or introducing new selftests.
