Revert commit c68f0676ef7d ("ACPI / battery: Add quirk for Asus
GL502VSK and UX305LA") and commit 4446823e2573 ("ACPI / battery: Add
quirk for Asus UX360UA and UX410UAK").
On many many Asus products, the battery is sometimes reported as
charging or discharging even when it is full and you are on AC power.
This change quirked the kernel to avoid advertising the discharging
state when this happens on 4 laptop models, under the belief that
this was incorrect information. I presume it originates from user
reports who are confused that their battery status icon says that it
is discharging.
However, the reported information is indeed correct, and the quirk
approach taken is inadequate and more thought is needed first.
Specifically:
1. It only quirks discharging state, not charging
2. There are so many different Asus products and DMI naming variants
within those product families that behave this way; Linux could
grow to quirk hundreds of products and still not even be close at
"winning" this battle.
3. Asus previously clarified that this behaviour is intentional. The
platform will periodically do a partial discharge/charge cycle
when the battery is full, because this is one way to extend the
lifetime of the battery (leaving a battery at 100% charge and
unused will decrease its usable capacity over time).
My understanding is that any decent consumer product will have
this behaviour, but it appears that Asus is different in that
they expose this info through ACPI.
However, the behaviour seems correct. The ACPI spec does not
suggest in that the platform should hide the truth. It lets you
report that the battery is full of charge, and discharging, and
with external power connected; and Asus does this.
4. In terms of not confusing the user, this seems like something that
could/should be handled by userspace, which can also detect these
same (accurate) conditions in the general case.
Revert this quirk before it gets included in a release, while we look
for better approaches.

Since commit 846c7dfc1193 ("drm/atomic: Try to preserve the crtc enabled
state in drm_atomic_remove_fb, v2."), removing the last framebuffer will
no longer disable the corresponding pipeline, which causes the KMS core
to complain about leaked connectors on driver unbind.
Fix this by calling drm_atomic_helper_shutdown() on driver unbind, which
will cause all display pipelines to be shut down and therefore drop the
extra references on the connectors.

When immediate quiet bit is set in CSA, the entire channel is blocked
by the firmware. It is expected that all the MACs will evacuate the
channel and the phy will be eventually either moved or removed.
Currently, the phy context is just unreferenced and thus, the quiet
bit is kept set and it will be impossible to TX on this phy, if we
will need to reuse it in the future. This can be seen when doing a
channel switch with mode=1 (quiet) twice from channel X to Y and then
back to channel X.
Fix that, by moving the phy context to a default channel when not
referenced anymore.

When starting aggregation, the code checks the status of the queue
allocated to the aggregation tid, which might not yet be allocated
and thus the queue index may be invalid.
Fix this by reserving a new queue in case the queue id is invalid.
While at it, clean up some unreachable code (a condition that is
already handled earlier) and remove all the non-DQA comments since
non-DQA mode is no longer supported.

If the driver failed to resume from D3, it is possible that it has
no valid aux station. In such case, fw restart will end up in sending
station related commands with an invalid station id, which will
result in an assert.

does not have a valid id even in the case of fw restart.

When a queue is reserved for aggregation, the queue id is assigned
to the tid_data. This is fine since iwl_mvm_sta_tx_agg_oper()
takes care of allocating the queue before actual tx starts.
When the reservation is cancelled (e.g. when the AP declined the
aggregation request) the tid_data is not cleared. As a result,
following tx for this tid was trying to use an unallocated queue.
Fix this by setting the txq_id for the tid to invalid when unreserving
the queue.

After switching to a new channel, driver schedules session protection
time event in order to hear the beacon on the new channel.
The duration of the protection is two beacon intervals.
However, since we start to switch slightly before beacon with count 1, in
case we don't hear (or AP doesn't transmit) the very first beacon on the
new channel the protection ends without hearing any beacon at all.
At this stage the switch is not complete, the queues are closed and the
interface doesn't have quota yet or TBTT events. As the result, we are
stuck forever waiting for iwl_mvm_post_channel_switch() to be called.
Fix this by increasing the protection time to be 3 beacon intervals and
in addition drop the connection if the time event ends before we got any
beacon.

====================
Automatic PHY interrupts
Now that the mv88e6xxx driver either installs in interrupt handler, or
polls for interrupts, it is possible to always handle PHY interrupts,
rather than have phylib perform the polling. This speeds up detection
of link changes and reduces the load on the MDIO bus, which is
beneficial for PTP.

When registering an MDIO bus, it is possible to pass an array of

interrupt to the PHY device, if no other interrupt is provided.

MDIO bus structure.

====================
ibmvnic: Update TX pool and TX routines
This patch restructures the TX pool data structure and provides a
separate TX pool array for TSO transmissions. This is already used
in some way due to our unique DMA situation, namely that we cannot
use single DMA mappings for packet data. Previously, both buffer
arrays used the same pool entry. This restructuring allows for
some additional cleanup in the driver code, especially in some
places in the device transmit routine.
In addition, it allows us to more easily track the consumer
and producer indexes of a particular pool. This has been
further improved by better tracking of in-use buffers to
prevent possible data corruption in case an invalid buffer
entry is used.
v5: Fix bisectability mistake in the first patch. Removed
TSO-specific data in a later patch when it is no longer used.
v4: Fix error in 7th patch that causes an oops by using
the older fixed value for number of buffers instead
of the respective field in the tx pool data structure
v3: Forgot to update TX pool cleaning function to handle new data
structures. Included 7th patch for that.

Improve TX pool buffer accounting to prevent the producer
index from overruning the consumer. First, set the next free
index to an invalid value if it is in use. If next buffer
to be consumed is in use, drop the packet.
Finally, if the transmit fails for some other reason, roll
back the consumer index and set the free map entry to its original
value. This should also be done if the DMA map fails.
