AUD_PAD_TOP widget's correct register is AFE_AUD_PAD_TOP , and not zero.
Having a zero as register, it would mean that the `snd_soc_dapm_new_widgets`
would try to read the register at offset zero when trying to get the power
status of this widget, which is incorrect.

If an application blocks on the snapshot or snapshot_raw files, expecting
to be woken up when a snapshot occurs, it will not happen. Or it may
happen with an unexpected result.
That result is that the application will be reading the main buffer
instead of the snapshot buffer. That is because when the snapshot occurs,
the main and snapshot buffers are swapped. But the reader has a descriptor
still pointing to the buffer that it originally connected to.
This is fine for the main buffer readers, as they may be blocked waiting
for a watermark to be hit, and when a snapshot occurs, the data that the
main readers want is now on the snapshot buffer.
But for waiters of the snapshot buffer, they are waiting for an event to
occur that will trigger the snapshot and they can then consume it quickly
to save the snapshot before the next snapshot occurs. But to do this, they
need to read the new snapshot buffer, not the old one that is now
receiving new data.
Also, it does not make sense to have a watermark "buffer_percent" on the
snapshot buffer, as the snapshot buffer is static and does not receive new
data except all at once.

The tracefs file "buffer_percent" is to allow user space to set a
water-mark on how much of the tracing ring buffer needs to be filled in
order to wake up a blocked reader.
0 - is to wait until any data is in the buffer
1 - is to wait for 1% of the sub buffers to be filled
50 - would be half of the sub buffers are filled with data
100 - is not to wake the waiter until the ring buffer is completely full
Unfortunately the test for being full was:
dirty = ring_buffer_nr_dirty_pages(buffer, cpu);
return (dirty * 100) > (full * nr_pages);
Where "full" is the value for "buffer_percent".
There is two issues with the above when full == 100.
1. dirty * 100 > 100 * nr_pages will never be true
That is, the above is basically saying that if the user sets
buffer_percent to 100, more pages need to be dirty than exist in the
ring buffer!
2. The page that the writer is on is never considered dirty, as dirty
pages are only those that are full. When the writer goes to a new
sub-buffer, it clears the contents of that sub-buffer.
That is, even if the check was ">=" it would still not be equal as the
most pages that can be considered "dirty" is nr_pages - 1.
To fix this, add one to dirty and use ">=" in the compare.

Commit 804951203aa5 ("platform/x86:intel/pmc: Combine core_init() and
core_configure()") caused a network performance regression due to the GBE
LTR ignore that it added at probe. This was needed in order to allow the
SoC to enter the deepest Package C state. To fix the regression and at
least support PC10 during suspend, move the LTR ignore from probe to the
suspend callback, and enable it again on resume. This solution will allow
PC10 during suspend but restrict Package C entry at runtime to no deeper
than PC8/9 while a network cable it attach to the PCH LAN.

Add a suspend callback to struct pmc for performing platform specific tasks
before device suspend. This is needed in order to perform GBE LTR ignore on
certain platforms at suspend-time instead of at probe-time and replace the

p2sb_bar() unhides P2SB device to get resources from the device. It
guards the operation by locking pci_rescan_remove_lock so that parallel
rescans do not find the P2SB device. However, this lock causes deadlock
when PCI bus rescan is triggered by /sys/bus/pci/rescan. The rescan
locks pci_rescan_remove_lock and probes PCI devices. When PCI devices
call p2sb_bar() during probe, it locks pci_rescan_remove_lock again.
Hence the deadlock.
To avoid the deadlock, do not lock pci_rescan_remove_lock in p2sb_bar().
Instead, do the lock at fs_initcall. Introduce p2sb_cache_resources()
for fs_initcall which gets and caches the P2SB resources. At p2sb_bar(),
refer the cache and return to the caller.

There are two problems with using regcache in this module.
The amplifier has 3 addressing levels (BOOK, PAGE, REG). The firmware
contains blocks that must be written to BOOK 0x8C. The regcache doesn't
know anything about BOOK, so regcache_sync writes invalid values to the
actual BOOK.
The module handles 2 or more separate amplifiers. The amplifiers have
different register values, and the module uses only one regmap/regcache
for all the amplifiers. The regcache_sync only writes the last amplifier
used.
The module successfully restores all the written register values (RC
profile, program, configuration, calibration) without regcache.
Remove regcache functions and set regmap cache_type to REGCACHE_NONE.

As explained in commit e03781879a0d ("drop_monitor: Require
'CAP_SYS_ADMIN' when joining "events" group"), the "flags" field in the
multicast group structure reuses uAPI flags despite the field not being
exposed to user space. This makes it impossible to extend its use
without adding new uAPI flags, which is inappropriate for internal
kernel checks.
Solve this by adding internal flags (i.e., "GENL_MCAST_*") and convert
the existing users to use them instead of the uAPI flags.
Tested using the reproducers in commit 44ec98ea5ea9 ("psample: Require
'CAP_NET_ADMIN' when joining "packets" group") and commit e03781879a0d
("drop_monitor: Require 'CAP_SYS_ADMIN' when joining "events" group").
No functional changes intended.

Currently the driver accepts VLAN TCI steering rules regardless of the

messages to the user.
There are two ways to handle the VLAN TCI mask:
1. Match on the PCP field using a VLAN prio filter
2. Match on complete TCI field using a flex filter
Therefore, add checks and code for that.
For instance the following rule is invalid and will be converted into a
VLAN prio rule which is not correct:

Stop dividing the phase_offset value received from firmware. This fault
is present since the initial implementation.
The phase_offset value received from firmware is in 0.01ps resolution.
Dpll subsystem is using the value in 0.001ps, raw value is adjusted
before providing it to the user.
The user can observe the value of phase offset with response to
`pin-get` netlink message of dpll subsystem for an active pin:
$ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml \
--do pin-get --json '{"id":2}'
Where example of correct response would be:
{'board-label': 'C827_0-RCLKA',
'capabilities': 6,
'clock-id': 4658613174691613800,
'frequency': 1953125,
'id': 2,
'module-name': 'ice',
'parent-device': [{'direction': 'input',
'parent-id': 6,
'phase-offset': -216839550,
'prio': 9,
'state': 'connected'},
{'direction': 'input',
'parent-id': 7,
'phase-offset': -42930,
'prio': 8,
'state': 'connected'}],
'phase-adjust': 0,
'phase-adjust-max': 16723,
'phase-adjust-min': -16723,
'type': 'mux'}
Provided phase-offset value (-42930) shall be divided by the user with
DPLL_PHASE_OFFSET_DIVIDER to get actual value of -42.930 ps.
Before the fix, the response was not correct:
{'board-label': 'C827_0-RCLKA',
'capabilities': 6,
'clock-id': 4658613174691613800,
'frequency': 1953125,

'state': 'connected'}],
'phase-adjust': 0,
'phase-adjust-max': 16723,
'phase-adjust-min': -16723,

Where phase-offset value (-42), after division
(DPLL_PHASE_OFFSET_DIVIDER) would be: -0.042 ps.

A freezable kernel thread can enter frozen state during freezing by
either calling try_to_freeze() or using wait_event_freezable() and its
variants. So for the following snippet of code in a kernel thread loop:
wait_event_interruptible_timeout();
try_to_freeze();
We can change it to a simple wait_event_freezable_timeout() and then
eliminate a function call.

Add MACsec support for TJA11XX C45 PHYs
This is the MACsec support for TJA11XX PHYs. The MACsec block encrypts
the ethernet frames on the fly and has no buffering. This operation will
grow the frames by 32 bytes. If the frames are sent back to back, the
MACsec block will not have enough room to insert the SecTAG and the ICV
and the frames will be dropped.
To mitigate this, the PHY can parse a specific ethertype with some
padding bytes and replace them with the SecTAG and ICV. These padding
bytes might be dummy or might contain information about TX SC that must
be used to encrypt the frame.

Add MACsec support.
The MACsec block has four TX SCs and four RX SCs. The driver supports up
to four SecY. Each SecY with one TX SC and one RX SC.
The RX SCs can have two keys, key A and key B, written in hardware and
enabled at the same time.
The TX SCs can have two keys written in hardware, but only one can be
active at a given time.
On TX, the SC is selected using the MAC source address. Due of this
selection mechanism, each offloaded netdev must have a unique MAC
address.
On RX, the SC is selected by SCI(found in SecTAG or calculated using MAC
SA), or using RX SC 0 as implicit.

Offloading MACsec in PHYs requires inserting the SecTAG and the ICV in
the ethernet frame. This operation will increase the frame size with up
to 32 bytes. If the frames are sent at line rate, the PHY will not have
enough room to insert the SecTAG and the ICV.
Some PHYs use a hardware buffer to store a number of ethernet frames and,
if it fills up, a pause frame is sent to the MAC to control the flow.
This HW implementation does not need any modification in the stack.
Other PHYs might offer to use a specific ethertype with some padding
bytes present in the ethernet frame. This ethertype and its associated
bytes will be replaced by the SecTAG and ICV.
mdo_insert_tx_tag allows the PHY drivers to add any specific tag in the
skb.
