While writel() takes the value and address arguments in that order, most
write functions (including in the regmap API) use the opposite
convention. Having the value first is considered confusing, and often
leads to more difficult to read code compared to the opposite convention
where the write call and the register name often fit on a single line:
rkisp1_write(rkisp1, RKISP1_CIF_THE_REG_NAME,
complicate_calculation + for / the_register
value + goes | here);
Swap the arguments of the rkisp1_write() function, and use the following
semantic patch to update the callers:
@@
expression rkisp1, value, address;
@@
- rkisp1_write(rkisp1, value, address)
+ rkisp1_write(rkisp1, address, value)
This commit also includes a few additional line break cleanups in the
rkisp1_write() calls, but no other manual change.

there is still one child clk(IMX8MP_CLK_MEDIA_ISP_ROOT) sourcing from

So IMX8MP_CLK_MEDIA_ISP_ROOT should be used, not IMX8MP_CLK_MEDIA_ISP_DIV.

A patch series from Sai Prakash Ranjan, who explains:
Generic MMIO read/write i.e., __raw_{read,write}{b,l,w,q} accessors
are typically used to read/write from/to memory mapped registers
and can cause hangs or some undefined behaviour in following cases,
* If the access to the register space is unclocked, for example: if
there is an access to multimedia(MM) block registers without MM
clocks.
* If the register space is protected and not set to be accessible from
non-secure world, for example: only EL3 (EL: Exception level) access
is allowed and any EL2/EL1 access is forbidden.
* If xPU(memory/register protection units) is controlling access to
certain memory/register space for specific clients.
and more...
Such cases usually results in instant reboot/SErrors/NOC or interconnect
hangs and tracing these register accesses can be very helpful to debug
such issues during initial development stages and also in later stages.
So use ftrace trace events to log such MMIO register accesses which
provides rich feature set such as early enablement of trace events,
filtering capability, dumping ftrace logs on console and many more.
Sample output:
rwmmio_write: __qcom_geni_serial_console_write+0x160/0x1e0 width=32 val=0xa0d5d addr=0xfffffbfffdbff700
rwmmio_post_write: __qcom_geni_serial_console_write+0x160/0x1e0 width=32 val=0xa0d5d addr=0xfffffbfffdbff700

Most layerscapes provide a security fuse processor where the vendor
will store a unique id per part. Unfortunately, we cannot use the
corresponding efuse driver because this driver needs to be ready
early during the boot phase. To get the unique identifier, we just
need to access two registers. Thus we just search the device tree
for the corresponding device, map its memory to read the id and then
unmap it again.
Because it is likely that the offset within the fuses is dependent
on the SoC, we need a per SoC data. Also, the compatible string is
different among the SoCs. For now, this add support for the LS1028A
SoC.

This appears to be the result of shortform_to_leaf creating a new leaf
buffer as part of adding an xattr to a file. The new leaf buffer is
held and attached to the xfs_attr_intent structure, but then the
filesystem shuts down. Instead of the usual path (which adds the attr
to the held leaf buffer which releases the hold), we instead cancel the
entire deferred operation.
Unfortunately, xfs_attr_cancel_item doesn't release any attached leaf
buffers, so we leak the locked buffer. The CIL cannot do anything
about that, and hangs. Fix this by teaching it to release leaf buffers,
and make XFS a little more careful about not leaving a dangling
reference.
The prologue of xfs_attri_item_recover is (in this author's opinion) a
little hard to figure out, so I'll clean that up in the next patch.

dma-direct: use the correct size for dma_set_encrypted()
Now that we introduced new infrastructure to increase the type safety
for filesystems supporting idmapped mounts port the first part of the
vfs over to them.
This ports the attribute changes codepaths to rely on the new better
helpers using a dedicated type.
Before this change we used to take a shortcut and place the actual
values that would be written to inode->i_{g,u}id into struct iattr. This
had the advantage that we moved idmappings mostly out of the picture
early on but it made reasoning about changes more difficult than it
should be.
The filesystem was never explicitly told that it dealt with an idmapped
mount. The transition to the value that needed to be stored in
inode->i_{g,u}id appeared way too early and increased the probability of
bugs in various codepaths.
We know place the same value in struct iattr no matter if this is an
idmapped mount or not. The vfs will only deal with type safe
vfs{g,u}id_t. This makes it massively safer to perform permission checks
as the type will tell us what checks we need to perform and what helpers
we need to use.
Fileystems raising FS_ALLOW_IDMAP can't simply write ia_vfs{g,u}id to
inode->i_{g,u}id since they are different types. Instead they need to
use the dedicated vfs{g,u}id_to_k{g,u}id() helpers that map the
vfs{g,u}id into the filesystem.
The other nice effect is that filesystems like overlayfs don't need to
care about idmappings explicitly anymore and can simply set up struct
iattr accordingly directly.

Port the is_quota_modification() and dqout_transfer() helper to type
safe vfs{g,u}id_t. Since these helpers are only called by a few
filesystems don't introduce a new helper but simply extend the existing
helpers to pass down the mount's idmapping.
Note, that this is a non-functional change, i.e. nothing will have
happened here or at the end of this series to how quota are done! This
a change necessary because we will at the end of this series make
ownership changes easier to reason about by keeping the original value
in struct iattr for both non-idmapped and idmapped mounts.
For now we always pass the initial idmapping which makes the idmapping
functions these helpers call nops.
This is done because we currently always pass the actual value to be
written to i_{g,u}id via struct iattr. While this allowed us to treat
the {g,u}id values in struct iattr as values that can be directly
written to inode->i_{g,u}id it also increases the potential for
confusion for filesystems.
Now that we are have dedicated types to prevent this confusion we will
ultimately only map the value from the idmapped mount into a filesystem
value that can be written to inode->i_{g,u}id when the filesystem
actually updates the inode. So pass down the initial idmapping until we
finished that conversion at which point we pass down the mount's
idmapping.
Since struct iattr uses an anonymous union with overlapping types as
supported by the C standard, filesystems that haven't converted to
ia_vfs{g,u}id won't see any difference and things will continue to work
as before. In other words, no functional changes intended with this
change.

Nearly all fileystems currently open-code the same checks for
determining whether the i_{g,u}id fields of an inode need to be updated
and then updating the fields.
Introduce tiny helpers i_{g,u}id_needs_update() and i_{g,u}id_update()
that wrap this logic. This allows filesystems to not care about updating
inode->i_{g,u}id with the correct values themselves instead leaving this
to the helpers.
We also get rid of a lot of code duplication and make it easier to
change struct iattr in the future since changes can be localized to
these helpers.
And finally we make it hard to conflate k{g,u}id_t types with
vfs{g,u}id_t types for filesystems that support idmapped mounts.
In the following patch we will port all filesystems that raise
FS_ALLOW_IDMAP to use the new helpers. However, the ultimate goal is to
convert all filesystems to make use of these helpers.
All new helpers are nops on non-idmapped mounts.

Add ia_vfs{g,u}id members of type vfs{g,u}id_t to struct iattr. We use
an anonymous union (similar to what we do in struct file) around
ia_{g,u}id and ia_vfs{g,u}id.
At the end of this series ia_{g,u}id and ia_vfs{g,u}id will always
contain the same value independent of whether struct iattr is
initialized from an idmapped mount. This is a change from how this is
done today.
Wrapping this in a anonymous unions has a few advantages. It allows us
to avoid needlessly increasing struct iattr. Since the types for
ia_{g,u}id and ia_vfs{g,u}id are structures with overlapping/identical
members they are covered by 6.5.2.3/6 of the C standard and it is safe
to initialize and access them.
Filesystems that raise FS_ALLOW_IDMAP and thus support idmapped mounts
will have to use ia_vfs{g,u}id and the associated helpers. And will be
ported at the end of this series. They will immediately benefit from the
type safe new helpers.
Filesystems that do not support FS_ALLOW_IDMAP can continue to use
ia_{g,u}id for now. The aim is to convert every filesystem to always use
ia_vfs{g,u}id and thus ultimately remove the ia_{g,u}id members.

Introduces new vfs{g,u}id_t types. Similar to k{g,u}id_t the new types
are just simple wrapper structs around regular {g,u}id_t types.
They allows to establish a type safety boundary between {g,u}ids on
idmapped mounts and {g,u}ids as they are represented in filesystems
themselves.
A vfs{g,u}id_t is always created from a k{g,u}id_t, never directly from
a {g,u}id_t as idmapped mounts remap a given {g,u}id according to the
mount's idmapping. This is expressed in the VFS{G,U}IDT_INIT() macros.
A vfs{g,u}id_t may be used as a k{g,u}id_t via AS_K{G,U}IDT(). This
often happens when we need to check whether a {g,u}id mapped according
to an idmapped mount is identical to a given k{g,u}id_t. For an example,
see vfsgid_in_group_p() which determines whether the value of vfsgid_t
matches the value of any of the caller's groups. Similar logic is
expressed in the k{g,u}id_eq_vfs{g,u}id().
The from_vfs{g,u}id() helpers map a given vfs{g,u}id_t from the mount's
idmapping into the filesystem idmapping. They make it possible to update
a filesystem object such as inode->i_{g,u}id with the correct value.
This makes it harder to accidently write a wrong {g,u}id anwywhere. The
vfs{g,u}id_has_fsmapping() helpers check whether a given vfs{g,u}id_t
can be mapped into the filesystem idmapping.
All new helpers are nops on non-idmapped mounts.
I've done work on this roughly 7 months ago but dropped it to focus on
the testsuite. Linus brought this up independently just last week and
it's time to move this along (see [1]).

Merge tag '5.19-rc3-smb3-client-fixes' of git://git.samba.org/sfrench/cifs-2.6
Pull cifs client fixes from Steve French:
"Fixes addressing important multichannel, and reconnect issues.
Multichannel mounts when the server network interfaces changed, or ip
addresses changed, uncovered problems, especially in reconnect, but
the patches for this were held up until recently due to some lock
conflicts that are now addressed.
Included in this set of fixes:
- three fixes relating to multichannel reconnect, dynamically
adjusting the list of server interfaces to avoid problems during
reconnect
- a lock conflict fix related to the above
- two important fixes for negotiate on secondary channels (null
netname can unintentionally cause multichannel to be disabled to
some servers)
- a reconnect fix (reporting incorrect IP address in some cases)"
* tag '5.19-rc3-smb3-client-fixes' of git://git.samba.org/sfrench/cifs-2.6:
cifs: update cifs_ses::ip_addr after failover
cifs: avoid deadlocks while updating iface
cifs: periodically query network interfaces from server
cifs: during reconnect, update interface if necessary
cifs: change iface_list from array to sorted linked list
smb3: use netname when available on secondary channels
smb3: fix empty netname context on secondary channels
