Both CAL and VIP rely on this clock domain. But CAL DPHY require
LVDSRX_96M_GFCLK to be active. When this domain is set to HWSUP the
LVDSRX_96M_GFCLK is on;y active when VIP1 clock is also active. If only
CAL on DRA72x (which uses the VIP2 clkctrl) probes the CAM domain is
enabled but the LVDSRX_96M_GFCLK is left gated. Since LVDSRX_96M_GFCLK
is sourcing the input clock to the DPHY then actual frame capture cannot
start as the phy are inactive.
So we either have to also enabled VIP1 even if we don't intend on using
it or we need to set the CAM domain to use SWSUP only.
This patch implements the latter.

Add clkctrl nodes for CAM domain.
Note that because of the current dts node name dependency for mapping to
clock domain, we must still use "cam-clkctrl@" naming instead of generic
"clock@" naming for the node. And because of this, it's probably best to
apply the dts node addition together along with the other clock changes.

Extents are cached in read_extent_tree_block(); as a result, extents

extent using ext4_find_extent(). The result of the lookup is cached
in ext4_map_blocks() but is only a subset of the extent on disk. As a

Sometimes when running generic/475 we would trip the
WARN_ON(cache->reserved) check when free'ing the block groups on umount.
This is because sometimes we don't commit the transaction because of IO
errors and thus do not cleanup the tree logs until at umount time.
These blocks are still reserved until they are cleaned up, but they
aren't cleaned up until _after_ we do the free block groups work. Fix
this by moving the free after free'ing the fs roots, that way all of the
tree logs are cleaned up and we have a properly cleaned fs. A bunch of
loops of generic/475 confirmed this fixes the problem.

Current code doesn't correctly handle the situation which arises when
a file system that has METADATA_UUID_INCOMPAT flag set and has its FSID
changed to the one in metadata uuid. This causes the incompat flag to
disappear.
In case of a power failure we could end up in a situation where part of
the disks in a multi-disk filesystem are correctly reverted to
METADATA_UUID_INCOMPAT flag unset state, while others have
METADATA_UUID_INCOMPAT set and CHANGING_FSID_V2_IN_PROGRESS.
This patch corrects the behavior required to handle the case where a
disk of the second type is scanned first, creating the necessary
btrfs_fs_devices. Subsequently, when a disk which has already completed
the transition is scanned it should overwrite the data in
btrfs_fs_devices.

There is one more cases which isn't handled by the original metadata

the user decides to change the FSID to the original one e.g. have
metadata_uuid and fsid match. In case of power failure while this
operation is in progress we could end up in a situation where some of
the disks have the incompat bit removed and the other half have both
METADATA_UUID_INCOMPAT and FSID_CHANGING_IN_PROGRESS flags.
This patch handles the case where a disk that has successfully changed
its FSID such that it equals METADATA_UUID is scanned first.
Subsequently when a disk with both
METADATA_UUID_INCOMPAT/FSID_CHANGING_IN_PROGRESS flags is scanned
find_fsid_changed won't be able to find an appropriate btrfs_fs_devices.
This is done by extending find_fsid_changed to correctly find
btrfs_fs_devices whose metadata_uuid/fsid are the same and they match
the metadata_uuid of the currently scanned device.

Recently fsstress (from fstests) sporadically started to trigger an
infinite loop during fsync operations. This turned out to be because
support for the rename exchange and whiteout operations was added to
fsstress in fstests. These operations, unlike any others in fsstress,
cause file names to be reused, whence triggering this issue. However
it's not necessary to use rename exchange and rename whiteout operations
trigger this issue, simple rename operations and file creations are
enough to trigger the issue.
The issue boils down to when we are logging inodes that conflict (that
had the name of any inode we need to log during the fsync operation), we
keep logging them even if they were already logged before, and after
that we check if there's any other inode that conflicts with them and
then add it again to the list of inodes to log. Skipping already logged
inodes fixes the issue.
Consider the following example:
$ mkfs.btrfs -f /dev/sdb
$ mount /dev/sdb /mnt
$ mkdir /mnt/testdir # inode 257
$ touch /mnt/testdir/zz # inode 258
$ ln /mnt/testdir/zz /mnt/testdir/zz_link
$ touch /mnt/testdir/a # inode 259
$ sync
# The following 3 renames achieve the same result as a rename exchange
# operation (<rename_exchange> /mnt/testdir/zz_link to /mnt/testdir/a).
$ mv /mnt/testdir/a /mnt/testdir/a/tmp
$ mv /mnt/testdir/zz_link /mnt/testdir/a
$ mv /mnt/testdir/a/tmp /mnt/testdir/zz_link
# The following rename and file creation give the same result as a
# rename whiteout operation (<rename_whiteout> zz to a2).
$ mv /mnt/testdir/zz /mnt/testdir/a2
$ touch /mnt/testdir/zz # inode 260
$ xfs_io -c fsync /mnt/testdir/zz
--> results in the infinite loop
The following steps happen:
1) When logging inode 260, we find that its reference named "zz" was
used by inode 258 in the previous transaction (through the commit
root), so inode 258 is added to the list of conflicting indoes that
need to be logged;
2) After logging inode 258, we find that its reference named "a" was
used by inode 259 in the previous transaction, and therefore we add
inode 259 to the list of conflicting inodes to be logged;
3) After logging inode 259, we find that its reference named "zz_link"
was used by inode 258 in the previous transaction - we add inode 258
to the list of conflicting inodes to log, again - we had already
logged it before at step 3. After logging it again, we find again
that inode 259 conflicts with him, and we add again 259 to the list,
etc - we end up repeating all the previous steps.
So fix this by skipping logging of conflicting inodes that were already
logged.

If we abort a transaction we have the following sequence
if (!trans->dirty && list_empty(&trans->new_bgs))
return;
WRITE_ONCE(trans->transaction->aborted, err);
The idea being if we didn't modify anything with our trans handle then
we don't really need to abort the whole transaction, maybe the other
trans handles are fine and we can carry on.
However in the case of create_snapshot we add a pending_snapshot object
to our transaction and then commit the transaction. We don't actually
modify anything. sync() behaves the same way, attach to an existing
transaction and commit it. This means that if we have an IO error in
the right places we could abort the committing transaction with our
trans->dirty being not set and thus not set transaction->aborted.
This is a problem because in the create_snapshot() case we depend on
pending->error being set to something, or btrfs_commit_transaction
returning an error.
If we are not the trans handle that gets to commit the transaction, and
we're waiting on the commit to happen we get our return value from
cur_trans->aborted. If this was not set to anything because sync() hit
an error in the transaction commit before it could modify anything then
cur_trans->aborted would be 0. Thus we'd return 0 from
btrfs_commit_transaction() in create_snapshot.
This is a problem because we then try to do things with
pending_snapshot->snap, which will be NULL because we didn't create the
snapshot, and then we'll get a NULL pointer dereference like the
following
"BUG: kernel NULL pointer dereference, address: 00000000000001f0"

In order to fix this we need to make sure anybody who calls
commit_transaction has trans->dirty set so that they properly set the
trans->transaction->aborted value properly so any waiters know bad
things happened.
This was found while I was running generic/475 with my modified
fsstress, it reproduced within a few runs. I ran with this patch all
night and didn't see the problem again.

New sysfs attributes that track the filesystem status of devices, stored
in the per-filesystem directory in /sys/fs/btrfs/FSID/devinfo . There's
a directory for each device, with name corresponding to the numerical
device id.
in_fs_metadata - device is in the list of fs metadata
missing - device is missing (no device node or block device)
replace_target - device is target of replace
writeable - writes from fs are allowed
These attributes reflect the state of the device::dev_state and created
at mount time.
Sample output:
$ pwd
/sys/fs/btrfs/6e1961f1-5918-4ecc-a22f-948897b409f7/devinfo/1/
$ ls
in_fs_metadata missing replace_target writeable
$ cat missing
0
The output from these attributes are 0 or 1. 0 indicates unset and 1
indicates set. These attributes are readonly.
It is observed that the device delete thread and sysfs read thread will
not race because the delete thread calls sysfs kobject_put() which in
turn waits for existing sysfs read to complete.
Note for device replace devid swap:
During the replace the target device temporarily assumes devid 0 before
assigning the devid of the soruce device.
In btrfs_dev_replace_finishing() we remove source sysfs devid using the
function btrfs_sysfs_remove_devices_attr(), so after that call
kobject_rename() to update the devid in the sysfs. This adds and calls
btrfs_sysfs_update_devid() helper function to update the device id.

Because interrupt mask register only affects assertion of the interrupt

So, there is problem, when we unmask interrupt with already

even if GPIO don't change their value since last unmask.

The Imgu acronyms are moved from header file into Document by previous
commit b8726aea59 ("media: ipu3: update meta format documentation"), so
the item can be removed from TODO list now.

This reverts commit e878742c83.
Imgu should still keep the capability and flexibility to allow user to
run 2 video pipes, as the user may use the video pipe to capture still
frames with less system load and power than still pipe.

In the current codes, the following 3 lines would be output to
the console for each irq line.
gpio gpiochip0: (gpio_thunderx): allocate IRQ 10, hwirq 0
gpio gpiochip0: (gpio_thunderx): found parent hwirq 245784
gpio gpiochip0: (gpio_thunderx): alloc_irqs_parent for 10 parent hwirq 245784
In general, there are about tens of irq lines for each gpio chip,
and then it would emit so many insignificant log in the boot process.
These infos are more suitable for the dbg purpose. So change these
to the dbg level. With this change, about 200 lines are suppressed
on my Marvell cn96xx board.

intel-pinctrl for v5.6-1
* Tiger Lake appears to have _HID enumeration, thus driver has been updated
* Coffee Lake-S has the same IP as Sunrisepoint, thus ID has been added
* Baytrail has got more clean ups and bug fixes, such as direct IRQ handling
* Lynxpoint GPIO has been converted to true pin control driver
* The common driver now uses IRQ chip enumeration via GPIO chip
The following is an automated git shortlog grouped by driver:
baytrail:
- Replace WARN with dev_info_once when setting direct-irq pin to output
- Do not clear IRQ flags on direct-irq enabled pins
- Reuse struct intel_pinctrl in the driver
- Use local variable to keep device pointer
- Keep pointer to struct device instead of its container
- Use GPIO direction definitions
- Move IRQ valid mask initialization to a dedicated callback
- Group GPIO IRQ chip initialization
- Allocate IRQ chip dynamic
cherryview:
- Use GPIO direction definitions
intel:
- Pass irqchip when adding gpiochip
- Add GPIO <-> pin mapping ranges via callback
- Share struct intel_pinctrl for wider use
- Use GPIO direction definitions
lynxpoint:
- Update summary in the driver
- Switch to pin control API
- Add GPIO <-> pin mapping ranges via callback
- Implement ->pin_dbg_show()
- Add pin control operations
- Reuse struct intel_pinctrl in the driver
- Add pin control data structures
- Implement intel_gpio_get_direction callback
- Implement ->irq_ack() callback
- Move ownership check to IRQ chip
- Move lp_irq_type() closer to IRQ related routines
- Move ->remove closer to ->probe()
- Extract lp_gpio_acpi_use() for future use
- Convert unsigned to unsigned int
- Switch to memory mapped IO accessors
- Keep pointer to struct device instead of its container
- Relax GPIO request rules
- Assume 2 bits for mode selector
- Use standard pattern for memory allocation
- Use %pR to print IO resource
- Drop useless assignment
- Correct amount of pins
- Use raw_spinlock for locking
- Move GPIO driver to pin controller folder
sunrisepoint:
- Add Coffee Lake-S ACPI ID
- Add missing Interrupt Status register offset
tigerlake:
- Tiger Lake uses _HID enumeration
When submitting v2 of "fou: Support binding FoU socket" (1713cb37bf),
I accidentally sent the wrong version of the patch and one fix was
missing. In the initial version of the patch, as well as the version 2
that I submitted, I incorrectly used ".type" for the two V6-attributes.
The correct is to use ".len".

====================
wireless-drivers fixes for v5.5
Second set of fixes for v5.5. There are quite a few patches,
especially on iwlwifi, due to me being on a long break. Libertas also
has a security fix and mt76 a build fix.
iwlwifi
* don't send the PPAG command when PPAG is disabled, since it can cause problems
* a few fixes for a HW bug
* a fix for RS offload;
* a fix for 3168 devices where the NVM tables where the wrong tables were being read
* fix a couple of potential memory leaks in TXQ code
* disable L0S states in all hardware since our hardware doesn't
officially support them anymore (and older versions of the hardware
had instability in these states)
* remove lar_disable parameter since it has been causing issues for
some people who erroneously disable it
* force the debug monitor HW to stop also when debug is disabled,
since it sometimes stays on and prevents low system power states
* don't send IWL_MVM_RXQ_NSSN_SYNC notification due to DMA problems
libertas
* fix two buffer overflows
mt76
* build fix related to CONFIG_MT76_LEDS
* fix off by one in bitrates handling

Keys queued for measurement should be freed if a custom IMA policy
was not loaded. Otherwise, the keys will remain queued forever
consuming kernel memory.
This patch defines a delayed workqueue to handle the above scenario.
The workqueue handler is setup to execute 5 minutes after IMA
initialization is completed.
If a custom IMA policy is loaded before the workqueue handler is
scheduled to execute, the workqueue task is cancelled and any queued keys
are processed for measurement. But if a custom policy was not loaded then
the queued keys are just freed when the delayed workqueue handler is run.
