[ Upstream commit 7d87bde21c73731ddaf15e572020f80999c38ee3 ]
The DMIC_GAINx_CUR registers contain the current (as in present) gain of
each DMIC. During capture, this gain will ramp up until a target value
is reached, and therefore the register is volatile since it is updated
automatically by hardware.
However, after capture the register's value returns to the value that
was written to it. So reading these registers returns the current gain,
and writing configures the initial gain for every capture.
>From an audio configuration perspective, reading the instantaneous gain
is not really useful. Instead, reading back the initial gain that was
configured is the desired behavior. For that reason, consider the
DMIC_GAINx_CUR registers as non-volatile, so the regmap's cache can be
used to retrieve the values, rather than requiring pm runtime resuming
the device.

Problem: Currently when running the "make isoimage" command there is an
error related to wrong parameters passed to the cp command:
"cp: missing destination file operand after 'arch/x86/boot/isoimage/'"
This is caused because FDINITRDS is an empty array.
Solution: Check if FDINITRDS is empty before executing the "cp" command,
similar to how it is done in the case of hdimage.

The syscon helper device_node_to_regmap() is used to fetch a regmap
registered to a device node. It also currently creates this regmap
if the node did not already have a regmap associated with it. This
should only be used on "syscon" nodes. This driver is not such a
device and instead uses device_node_to_regmap() on its own node as
a hacky way to create a regmap for itself.
This will not work going forward and so we should create our regmap
the normal way by defining our regmap_config, fetching our memory
resource, then using the normal regmap_init_mmio() function.

Currently, sometimes, the station is unable to identify the configured
AP SSID in its scan results when the AP is not broadcasting its name
publicly and has a hidden SSID.
Currently, channel dwell time for an ath12k station is 30 ms. Sometimes,
station can send broadcast probe request to AP close to the end of dwell
time. In some of these cases, before AP sends a response to the received
probe request, the dwell time on the station side would come to an end.
So, the station will move to scan next channel and will not be able to
acknowledge the unicast probe response.
Resolve this issue by increasing station's channel dwell time to 70 ms,
so that the it remains on the same channel for a longer period. This
would increase the station's chance of receiving probe response from the
AP. The station will then send a response acknowledgment back to the AP,
thus leading to successful scan and BSS discovery.
With an increased dwell time, scan would take longer than it takes now.
But, this fix is an improvement for hidden SSID scan issue.

But these failure status is due to internal firmware tx drop and these

In case of mesh this invalid tx status report might trigger mpath broken

So do not report these tx status as tx failure instead free the skb

Currently, user mode spectre v2 is set to auto
(SPECTRE_V2_USER_CMD_AUTO) by default, even if

Set the spectre_v2 value to auto (SPECTRE_V2_USER_CMD_AUTO) if the

set the value to none (SPECTRE_V2_USER_CMD_NONE).
Important to say the command line argument "spectre_v2_user" overwrites

When CONFIG_MITIGATION_SPECTRE_V2 is not set, users have the flexibility
to opt-in for specific mitigations independently. In this scenario,
setting spectre_v2= will not enable spectre_v2_user=, and command line
options spectre_v2_user and spectre_v2 are independent when

The IMX8MPCEC datasheet lists maximum frequencies allowed for different
modules. Some of these limits are universal, but some depend on
whether the SoC is operating in nominal or in overdrive mode.
The imx8mp.dtsi currently assumes overdrive mode and configures some
clocks in accordance with this. Boards wishing to make use of nominal
mode will need to override some of the clock rates manually.
As operating the clocks outside of their allowed range can lead to
difficult to debug issues, it makes sense to register the maximum rates
allowed in the driver, so the CCF can take them into account.

PC speaker works well on this platform in BIOS and in Linux until sound
card drivers are loaded. Then it stops working.
There seems to be a beep generator node at 0x1a in this CODEC
(ALC269_TYPE_ALC215) but it seems to be only connected to capture mixers
at nodes 0x22 and 0x23.
If I unmute the mixer input for 0x1a at node 0x23 and start recording
from its "ALC285 Analog" capture device I can clearly hear beeps in that
recording.
So the beep generator is indeed working properly, however I wasn't able to
figure out any way to connect it to speakers.
However, the bits in the "Passthrough Control" register (0x36) seems to
work at least partially: by zeroing "B" and "h" and setting "S" I can at
least make the PIT PC speaker output appear either in this laptop speakers
or headphones (depending on whether they are connected or not).
There are some caveats, however:
* If the CODEC gets runtime-suspended the beeps stop so it needs HDA beep
device for keeping it awake during beeping.
* If the beep generator node is generating any beep the PC beep passthrough
seems to be temporarily inhibited, so the HDA beep device has to be
prevented from using the actual beep generator node - but the beep device
is still necessary due to the previous point.
* In contrast with other platforms here beep amplification has to be
disabled otherwise the beeps output are WAY louder than they were on pure
BIOS setup.
Unless someone (from Realtek probably) knows how to make the beep generator
node output appear in speakers / headphones using PC beep passthrough seems
to be the only way to make PC speaker beeping actually work on this
platform.

Both MSM8974 and MSM8226 have only CX as power domain with MX & PX being
handled as regulators. Handle this case by reodering pd_names to have CX
first, and handling that the driver core will already attach a single
power domain internally.

[ Upstream commit b63263555eaafbf9ab1a82f2020bbee872d83759 ]
The phylink_expects_phy() function allows MAC drivers to check if they are
expecting a PHY to attach. The checking condition in phylink_expects_phy()
aims to achieve the same result as the checking condition in
phylink_attach_phy().
However, the checking condition in phylink_expects_phy() uses
pl->link_config.interface, while phylink_attach_phy() uses
pl->link_interface.
Initially, both pl->link_interface and pl->link_config.interface are set
to SGMII, and pl->cfg_link_an_mode is set to MLO_AN_INBAND.
When the interface switches from SGMII to 2500BASE-X,
pl->link_config.interface is updated by phylink_major_config().
At this point, pl->cfg_link_an_mode remains MLO_AN_INBAND, and
pl->link_config.interface is set to 2500BASE-X.
Subsequently, when the STMMAC interface is taken down
administratively and brought back up, it is blocked by
phylink_expects_phy().
Since phylink_expects_phy() and phylink_attach_phy() aim to achieve the
same result, phylink_expects_phy() should check pl->link_interface,
which never changes, instead of pl->link_config.interface, which is
updated by phylink_major_config().

[ Upstream commit b57aa47d39e94dc47403a745e2024664e544078c ]
Add drm_gem_is_imported() that tests if a GEM object's buffer has
been imported. Update the GEM code accordingly.
GEM code usually tests for imports if import_attach has been set
in struct drm_gem_object. But attaching a dma-buf on import requires
a DMA-capable importer device, which is not the case for many serial
busses like USB or I2C. The new helper tests if a GEM object's dma-buf
has been created from the GEM object.

[ Upstream commit b773530a34df0687020520015057075f8b7b4ac4 ]
An of_node_put(i2c_bus) call was immediately used after a pointer check
for an of_find_i2c_adapter_by_node() call in this function implementation.
Thus call such a function only once instead directly before the check.
This issue was transformed by using the Coccinelle software.

Use proper setters and getters for bitwise types.

[ Upstream commit e3cd33ab17c33bd8f1a9df66ec83a15dd8f7afbb ]
snd_seq_poll() calls snd_seq_write_pool_allocated() that reads out a
field in client->pool object, while it can be updated concurrently via
ioctls, as reported by syzbot. The data race itself is harmless, as
it's merely a poll() call, and the state is volatile. OTOH, the read
out of poll object info from the caller side is fragile, and we can
leave it better in snd_seq_pool_poll_wait() alone.
A similar pattern is seen in snd_seq_kernel_client_write_poll(), too,
which is called from the OSS sequencer.
This patch drops the pool checks from the caller side and add the
pool->lock in snd_seq_pool_poll_wait() for better data consistency.
