ana->maskX values are already '~'-ed in bcm2835_pll_set_rate(). Remove
the '~' in the definition to fix ANA setup.
Note that this commit fixes a long standing bug preventing one from
using an HDMI display if it's plugged after the FW has booted Linux.
This is because PLLH is used by the HDMI encoder to generate the pixel
clock.

When commit 9c7be59fc519af ("libata: Apply NOLPM quirk to Crucial MX100
512GB SSDs") was added it inherited the ATA_HORKAGE_NO_NCQ_TRIM quirk
from the existing "Crucial_CT*MX100*" entry, but that entry sets model_rev
to "MU01", where as the entry adding the NOLPM quirk sets it to NULL.
This means that after this commit we no apply the NO_NCQ_TRIM quirk to
all "Crucial_CT512MX100*" SSDs even if they have the fixed "MU02"
firmware. This commit splits the "Crucial_CT512MX100*" quirk into 2
quirks, one for the "MU01" firmware and one for all other firmware
versions, so that we once again only apply the NO_NCQ_TRIM quirk to the
"MU01" firmware version.

Commit b17e5729a630 ("libata: disable LPM for Crucial BX100 SSD 500GB
drive"), introduced a ATA_HORKAGE_NOLPM quirk for Crucial BX100 500GB SSDs
but limited this to the MU02 firmware version, according to:
http://www.crucial.com/usa/en/support-ssd-firmware
MU02 is the last version, so there are no newer possibly fixed versions
and if the MU02 version has broken LPM then the MU01 almost certainly
also has broken LPM, so this commit changes the quirk to apply to all
firmware versions.

There have been reports of the Crucial M500 480GB model not working
with LPM set to min_power / med_power_with_dipm level.
It has not been tested with medium_power, but that typically has no
measurable power-savings.
Note the reporters Crucial_CT480M500SSD3 has a firmware version of MU03
and there is a MU05 update available, but that update does not mention any
LPM fixes in its changelog, so the quirk matches all firmware versions.
In my experience the LPM problems with (older) Crucial SSDs seem to be
limited to higher capacity versions of the SSDs (different firmware?),
so this commit adds a NOLPM quirk for the 480 and 960GB versions of the
M500, to avoid LPM causing issues with these SSDs.

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 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.

'Commit 45dac1d6ea04 ("vmxnet3: Changes for vmxnet3 adapter version 2
(fwd)")' introduced a flag "lro" in structure vmxnet3_adapter which is
used to indicate whether LRO is enabled or not. However, the patch
did not set the flag and hence it was never exercised.
So, when LRO is enabled, it resulted in poor TCP performance due to
delayed acks. This issue is seen with packets which are larger than
the mss getting a delayed ack rather than an immediate ack, thus
resulting in high latency.
This patch removes the lro flag and directly uses device features
against NETIF_F_LRO to check if lro is enabled.

The field txNumDeferred is used by the driver to keep track of the number
of packets it has pushed to the emulation. The driver increments it on
pushing the packet to the emulation and the emulation resets it to 0 at
the end of the transmit.
There is a possibility of a race either when (a) ESX is under heavy load or
(b) workload inside VM is of low packet rate.
This race results in xmit hangs when network coalescing is disabled. This
change creates a local copy of txNumDeferred and uses it to perform ring
arithmetic.

In commit 9ffcc3725f09 ("mlxsw: spectrum: Allow packets to be trapped
from any PG") I fixed a problem where packets could not be trapped to
the CPU due to exceeded shared buffer quotas. The mentioned commit
explains the problem in detail.
The problem was fixed by assigning a minimum quota for the CPU port and
the traffic class used for scheduling traffic to the CPU.
However, commit 117b0dad2d54 ("mlxsw: Create a different trap group list
for each device") assigned different traffic classes to different
packet types and rendered the fix useless.
Fix the problem by assigning a minimum quota for the CPU port and all
the traffic classes that are currently in use.

There is no need for complex checking between the last consumed index
and current consumed index, a simple subtraction will do.
This also eliminates the possibility of a permanent transmit queue stall
under the following conditions:
- one CPU bursts ring->size worth of traffic (up to 256 buffers), to the
point where we run out of free descriptors, so we stop the transmit
queue at the end of bcm_sysport_xmit()
- because of our locking, we have the transmit process disable
interrupts which means we can be blocking the TX reclamation process
- when TX reclamation finally runs, we will be computing the difference
between ring->c_index (last consumed index by SW) and what the HW
reports through its register
- this register is masked with (ring->size - 1) = 0xff, which will lead
to stripping the upper bits of the index (register is 16-bits wide)
- we will be computing last_tx_cn as 0, which means there is no work to
be done, and we never wake-up the transmit queue, leaving it
permanently disabled
A practical example is e.g: ring->c_index aka last_c_index = 12, we
pushed 256 entries, HW consumer index = 268, we mask it with 0xff = 12,
so last_tx_cn == 0, nothing happens.

Testing brcmfmac with more recent firmwares resulted in AP interfaces
not working in some specific setups. Debugging resulted in discovering
support for IAPP in Broadcom's firmwares.
Older firmwares were only generating 802.11f frames. Newer ones like:
1) 10.10 (TOB) (r663589)
2) 10.10.122.20 (r683106)
for 4366b1 and 4366c0 respectively seem to also /respect/ 802.11f frames
in the Tx path by performing a STA disassociation.
This obsoleted standard and its implementation is something that:
1) Most people don't need / want to use
2) Can allow local DoS attacks
3) Breaks AP interfaces in some specific bridge setups
To solve issues it can cause this commit modifies brcmfmac to drop IAPP
packets. If affects:
1) Rx path: driver won't be sending these unwanted packets up.
2) Tx path: driver will reject packets that would trigger STA
disassociation perfromed by a firmware (possible local DoS attack).
It appears there are some Broadcom's clients/users who care about this
feature despite the drawbacks. They can switch it on using a new module
param.
This change results in only two more comparisons (check for module param
and check for Ethernet packet length) for 99.9% of packets. Its overhead
should be very minimal.

The tid being used for the queue (cab_queue) for the MCAST
station has been changed recently to be 0 (for BE).
The flush path still flushed only the special tid (15)
which means that the firmware wasn't flushing the right
queue and we could get a firmware crash upon remove
station if we had an MCAST packet on the ring.
The current code that flushes queues for a station only
differentiates between internal stations (stations that
aren't instantiated in mac80211, like the MCAST station)
and the non-internal ones.
Internal stations can be either: BCAST (beacons), MCAST
(for cab_queue), GENERAL_PURPOSE (p2p dev, and sniffer
injection). The internal stations can use different tids.
To make the code simpler, just flush all the tids always
and add the special internal tid (15) for internal
stations. The firmware will know how to handle this even
if we hadn't any queue mapped that that tid.

It was found that in IDMAC mode after soft-reset driver switches
to PIO mode.
That's what happens in case of DTO timeout overflow calculation failure:
1. soft-reset is called
2. driver restarts dma
3. descriptors states are checked, one of descriptor is owned by the IDMAC.
4. driver can't use DMA and then switches to PIO mode.
Failure was already fixed in:
https://www.spinics.net/lists/linux-mmc/msg48125.html.
Behaviour while soft-reset is not something we except or
even want to happen. So we switch from dw_mci_idmac_reset
to dw_mci_idmac_init, so descriptors are cleaned before starting dma.
And while at it explicitly zero des0 which otherwise might
contain garbage as being allocated by dmam_alloc_coherent().

Commit 99759869faf1 "acpi: Add acpi_map_pxm_to_online_node()" added
support for mapping a given proximity to its nearest, by SLIT distance,
online node. However, it sometimes returns unexpected results due to the
fact that it switches from comparing the PXM node to the last node that
was closer than the current max.
for_each_online_node(n) {
dist = node_distance(node, n);
if (dist < min_dist) {
min_dist = dist;
node = n; <---- from this point we're using the
wrong node for node_distance()

The IRQ output of the bcm bt-device is really a level IRQ signal, which
signals a logical high as long as the device's buffer contains data. Since
the draining in the buffer is done in the tty driver, we cannot (easily)
wait in a threaded interrupt handler for the draining, after which the
IRQ should go low again.
So instead we treat the IRQ as an edge interrupt. This opens the window
for a theoretical race where we wakeup, read some data and then autosuspend
*before* the IRQ has gone (logical) low, followed by the device just at
that moment receiving more data, causing the IRQ to stay high and we never
see an edge.
Since we call pm_runtime_mark_last_busy() on every received byte, there
should be plenty time for the IRQ to go (logical) low before we ever
suspend, so this should never happen, but after commit 43fff7683468
("Bluetooth: hci_bcm: Streamline runtime PM code"), which has been reverted
since, this was actually happening causing the device to get stuck in
runtime suspend.
The bcm bt-device actually has a workaround for this, if we set the
pulsed_host_wake flag in the sleep parameters, then the device monitors
if the host is draining the buffer and if not then after a timeout the
device will pulse the IRQ line, causing us to see an edge, fixing the
stuck in suspend condition.
This commit sets the pulsed_host_wake flag to fix the (mostly theoretical)
race caused by us treating the IRQ as an edge IRQ.

This reverts commit 43fff7683468 ("Bluetooth: hci_bcm: Streamline runtime

intended.", but replacing:
pm_runtime_get();
pm_runtime_mark_last_busy();
pm_runtime_put_autosuspend();
with:
pm_request_resume();
Does result in a functional change, pm_request_resume() only calls
pm_runtime_mark_last_busy() if the device was suspended before the call.
This results in the following happening:
1) Device is runtime suspended
2) Device drives host_wake IRQ logically high as it starts receiving data
3) bcm_host_wake() gets called, causes the device to runtime-resume,
current time gets marked as last_busy time
4) After 5 seconds the autosuspend timer expires and the dev autosuspends
as no one has been calling pm_runtime_mark_last_busy(), the device was
resumed during those 5 seconds, so all the pm_request_resume() calls
while receiving data and/or bcm_host_wake() calls were nops
5) If 4) happens while the device has (just received) data in its buffer to
be read by the host the IRQ line is *already* / still logically high
when we autosuspend and since we use an edge triggered IRQ, the IRQ
will never trigger, causing the device to get stuck in suspend
Therefor this commit has to be reverted, so that we avoid the device
getting stuck in suspend.

The Atheros 1525/QCA6174 BT doesn't seem working properly on the
recent kernels, as it tries to load a wrong firmware
ar3k/AthrBT_0x00000200.dfu and it fails.
This seems to have been a problem for some time, and the known
workaround is to apply BTUSB_QCA_ROM quirk instead of BTUSB_ATH3012.
The device in question is:

According to the Aspeed specification, the reset and enable sequence
should be done when the clock is stopped. The specification doesn't
define behavior if the reset is done while the clock is enabled.
From testing on the AST2500, the LPC Controller has problems if the
clock is reset while enabled.
Therefore, check whether the clock is enabled or not before performing
the reset and enable sequence in the Aspeed clock driver.
