The programming of the DPHY vs. DSI _TIMING registers are
two separate steps in the TGL+ bspec sequence, with some
other stuff in between. Implement the same split.
Windows also seems follow the bspec TGL+ sequence, even
on ICL/JSL.

Export Passive version 2 table similar to the way _TRT and _ART tables
via IOCTLs.
This removes need for binary utility to read ACPI Passive 2 table by
providing open source support. This table already has open source
implementation in the user space thermald, when the table is part of
data vault exported by the int3400 sysfs.
This table is supported in some older platforms before Ice Lake
generation.
Passive 2 tables contain multiple entries. Each entry has following
fields:
* Source: Named Reference (String). This is the source device for
temperature.
* Target: Named Reference (String). This is the target device to
control.
* Priority: Priority of this device compared to others.
* SamplingPeriod: Time Period in 1/10 of seconds unit.
* PassiveTemp: Passive Temperature in 1/10 of Kelvin.
* SourceDomain: Domain for the source (00:Processor, others reserved).
* ControlKnob: Type of control knob (00:Power Limit 1, others: reserved)
* Limit: The target state to set on reaching passive temperature.
This can be a string "max", "min" or a power limit value.
* LimitStepSize: Step size during activation.
* UnLimitStepSize: Step size during deactivation.
* Reserved1: Reserved
Three IOCTLs are added similar to IOCTLs for reading TRT:
ACPI_THERMAL_GET_PSVT_COUNT: Number of passive 2 entries.
ACPI_THERMAL_GET_PSVT_LEN: Total return data size (count x each
passive 2 entry size).
ACPI_THERMAL_GET_PSVT: Get the data as an array of objects with
passive 2 entries.

The bug can be reproduced with the following sequence:
# truncate -s 1073741824 xfs_test.img
# mkfs.xfs -f -b size=1024 -d agcount=4 xfs_test.img
# truncate -s 2305843009213693952 xfs_test.img
# mount -o loop xfs_test.img /mnt/test
# xfs_growfs -D 1125899907891200 /mnt/test
The root cause is that during growfs, user space passed in a large value
of newblcoks to xfs_growfs_data_private(), due to current sb_agblocks is
too small, new AG count will exceed UINT_MAX. Because of AG number type
is unsigned int and it would overflow, that caused nagcount much smaller
than the actual value. During AG extent space, delta blocks in
xfs_resizefs_init_new_ags() will much larger than the actual value due to
incorrect nagcount, even exceed UINT_MAX. This will cause corruption and
be detected in __xfs_free_extent. Fix it by growing the filesystem to up
to the maximally allowed AGs and not return EINVAL when new AG count
overflow.

When using dm-verity with a data partition on an emmc device, dm-verity
races with the initialization of the (e)MMC/SD cards. This is because the
card detection procedure is being managed from a workqueue, rather than
synchronously from the mmc host's ->probe() routine.
To allow the card detect to be synchronous, let's simply skip using the
workqueue at the first initialization attempt from mmc_start_host().

GPIO0 is statically configured as input or output prior to Linux boot.
it is used for MULTI_DEVICE_ENABLE function.
This setting is statically configured by NVM.
GPIO0 can't be used as a generic GPIO (specification Table 8-34).
It's either a GPO when MULTI_DEVICE_EN=0 or a GPI when MULTI_DEVICE_EN=1.

Some fields such as gt_logd_secs of the struct gfs2_tune are accessed
without holding the lock gt_spin in gfs2_show_options():
val = sdp->sd_tune.gt_logd_secs;
if (val != 30)
seq_printf(s, ",commit=%d", val);
And thus can cause data races when gfs2_show_options() and other functions
such as gfs2_reconfigure() are concurrently executed:
spin_lock(>->gt_spin);
gt->gt_logd_secs = newargs->ar_commit;
To fix these possible data races, the lock sdp->sd_tune.gt_spin is
acquired before accessing the fields of gfs2_tune and released after these
accesses.

`_regmap_update_bits()` checks if the current register value differs
from the new value, and only writes to the register if they differ. When
testing hardware drivers, it might be desirable to always force a
register write, for example when writing to a `regmap_field`. This
enables and simplifies testing and verification of the hardware
interaction. For example, when using a hardware mock/simulation model,
one can then more easily verify that the driver makes the correct
expected register writes during certain events.
Add a bool variable `force_write_field` and a corresponding debugfs
entry to enable this. Since this feature could interfere with driver
operation, guard it with a macro.

regcache_maple_sync() tries to sync all cached values no matter
whether it's writable or not. OTOH, regache_sync_val() does care the
wrtability and returns -EIO for a read-only register. This results in
an error message like:
snd_hda_codec_realtek hdaudioC0D0: Unable to sync register 0x2f0009. -5
and the sync loop is aborted incompletely.
This patch adds the writable register check to regcache_sync_val() for
addressing the bug above.
Note that, although we may add the check in the caller side
(regcache_maple_sync()), here we put in regcache_sync_val(), so that a
similar case like this can be avoided in future.

Currently, ASoC supports dailinks with the following mappings:
1 cpu DAI to N codec DAIs
N cpu DAIs to N codec DAIs
But the mapping between N cpu DAIs and M codec DAIs is not supported.
The reason is that we didn't have a mechanism to map cpu and codec DAIs
This patch suggests a new snd_soc_dai_link_codec_ch_map struct in
struct snd_soc_dai_link{} which provides codec DAI to cpu DAI mapping
information used to implement N cpu DAIs to M codec DAIs
support.
When a dailink contains two or more cpu DAIs, we should set channel
number of cpus based on its channel mask. The new struct also provides
channel mask information for each codec and we can construct the cpu
channel mask by combining all codec channel masks which map to the cpu.
The N:M mapping is however restricted to the N <= M case due to physical
restrictions on a time-multiplexed bus such as I2S/TDM, AC97, SoundWire
and HDaudio.

Commit 3ed2b549b3 ("ALSA: pcm: fix wait_time calculations") corrected
the PCM wait_time calculations and in doing so reduced the calculated
wait_time. This exposed an issue with the Tegra Master Volume Control
(MVC) device where the reduced wait_time caused the MVC to fail. For now
fix this by setting the default wait_time for Tegra to be 500ms.

Ext2 has fields in superblock reserved for subblock allocation support.
However that never landed. Drop the many years dead code.

On multi package system, the TPMI SST instance is getting allocated
again as the usage counter is not getting incremented. Here the
instance is allocated only when the usage count is zero. There is
no need to allocate again.
Increment usage ID on successful return from isst_if_cdev_register().

When multiple clients are registered and some of those modules are
removed, the default IOCTL callback for those clients are still not
NULL. Calling them will result in crash.
Set the default IOCTL callback pointer to NULL on unregister.
