It seems that this driver was developed based on preliminary documentation.
Report the correct names for all TQMxE39x variants, as they are used by
the released hardware revisions:
- Fix names for TQMxE39C1/C2 board IDs
- Distinguish TQMxE39M and TQMxE39S, which use the same board ID
The TQMxE39M/S are distinguished using the SAUC (Sanctioned Alternate
Uses Configuration) register of the GPIO controller. This also prepares
for the correct handling of the differences between the GPIO controllers
of our COMe and SMARC modules.

Registers 0x160..0x17f are unassigned. Use 0x180 as base register and
update offets accordingly.
Also change the size of the range to include 0x19f. While 0x19f is
currently reserved for future extensions, so are several of the previous
registers up to 0x19e, and it is weird to leave out just the last one.

The I2C_DETECT register is at IO port 0x1a7, which is outside the range
passed to devm_ioport_map() for io_base, and was only working because
there aren't actually any bounds checks for IO port accesses.
Extending the range does not seem like a good solution here, as it would
then conflict with the IO resource assigned to the I2C controller. As
this is just a one-off access during probe, use a simple inb() instead.
While we're at it, drop the unused define TQMX86_REG_I2C_INT_EN.

are used to identify modules. As a consequence, uses of the macro

Remove pm8008_init(), which according to the comments exists only
as a workaround for regmap-irq's odd treatment of type registers.
This workaround shouldn't be needed anymore because this driver
uses config registers, which are always programmed by regmap-irq
no matter what the initial register state is.

The usual behavior of mask registers is writing a '1' bit to
disable (mask) an interrupt; similarly, writing a '1' bit to
an unmask register enables (unmasks) an interrupt.
Due to a longstanding issue in regmap-irq, mask and unmask
registers were inverted when both kinds of registers were
present on the same chip, ie. regmap-irq actually wrote '1's
to the mask register to enable an IRQ and '1's to the unmask
register to disable an IRQ.
This was fixed by commit e8ffb12e7f ("regmap-irq: Fix
inverted handling of unmask registers") but the fix is opt-in
via mask_unmask_non_inverted = true because it requires manual
changes for each affected driver. The new behavior will become
the default once all drivers have been updated.
The PM8008 appears to rely on the inverted behavior. It has
separate set & clear registers for a register called INT_EN,
which presumably enables interrupts by writing '1's. Opt in
to the new non-inverted behavior & swap mask_base/unmask_base.

There is a problem with the behavior of hwlat in a container,
resulting in incorrect output. A warning message is generated:
"cpumask changed while in round-robin mode, switching to mode none",
and the tracing_cpumask is ignored. This issue arises because
the kernel thread, hwlatd, is not a part of the container, and
the function sched_setaffinity is unable to locate it using its PID.
Additionally, the task_struct of hwlatd is already known.
Ultimately, the function set_cpus_allowed_ptr achieves
the same outcome as sched_setaffinity, but employs task_struct
instead of PID.
Test case:
# cd /sys/kernel/tracing
# echo 0 > tracing_on
# echo round-robin > hwlat_detector/mode
# echo hwlat > current_tracer
# unshare --fork --pid bash -c 'echo 1 > tracing_on'
# dmesg -c

The hwlatd tracer will end up starting multiple per-cpu threads with
the following script:
#!/bin/sh
cd /sys/kernel/debug/tracing
echo 0 > tracing_on
echo hwlat > current_tracer
echo per-cpu > hwlat_detector/mode
echo 100000 > hwlat_detector/width

To fix the issue, check if the hwlatd thread for the cpu is already
running, before starting a new one. Along with the previous patch, this
avoids running multiple instances of the same CPU thread on the system.

Overwriting the error code with the deletion result may cause the

("tracing: Remove the useless value assignment in

returning the original error code, so this patch does the same.

The __find_restype() function loops over the m5mols_default_ffmt[]
array, and the termination condition ends up being wrong: instead of
stopping when the iterator becomes the size of the array it traverses,
it stops after it has already overshot the array.
Now, in practice this doesn't likely matter, because the code will
always find the entry it looks for, and will thus return early and never
hit that last extra iteration.
But it turns out that clang will unroll the loop fully, because it has
only two iterations (well, three due to the off-by-one bug), and then
clang will end up just giving up in the middle of the loop unrolling
when it notices that the code walks past the end of the array.
And that made 'objtool' very unhappy indeed, because the generated code
just falls off the edge of the universe, and ends up falling through to
the next function, causing this warning:
drivers/media/i2c/m5mols/m5mols.o: warning: objtool: m5mols_set_fmt() falls through to next function m5mols_get_frame_desc()
Fix the loop ending condition.

Merge tag 'net-6.3-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski:
"Including fixes from netfilter, wifi and ipsec.
A little more changes than usual, but it's pretty normal for us that
the rc3/rc4 PRs are oversized as people start testing in earnest.
Possibly an extra boost from people deploying the 6.1 LTS but that's
more of an unscientific hunch.
Current release - regressions:
- phy: mscc: fix deadlock in phy_ethtool_{get,set}_wol()
- virtio: vsock: don't use skbuff state to account credit
- virtio: vsock: don't drop skbuff on copy failure
- virtio_net: fix page_to_skb() miscalculating the memory size
Current release - new code bugs:
- eth: correct xdp_features after device reconfig
- wifi: nl80211: fix the puncturing bitmap policy
- net/mlx5e: flower:
- fix raw counter initialization
- fix missing error code
- fix cloned flow attribute
- ipa:
- fix some register validity checks
- fix a surprising number of bad offsets
- kill FILT_ROUT_CACHE_CFG IPA register
Previous releases - regressions:
- tcp: fix bind() conflict check for dual-stack wildcard address
- veth: fix use after free in XDP_REDIRECT when skb headroom is small
- ipv4: fix incorrect table ID in IOCTL path
- ipvlan: make skb->skb_iif track skb->dev for l3s mode
- mptcp:
- fix possible deadlock in subflow_error_report
- fix UaFs when destroying unaccepted and listening sockets
- dsa: mv88e6xxx: fix max_mtu of 1492 on 6165, 6191, 6220, 6250, 6290
Previous releases - always broken:
- tcp: tcp_make_synack() can be called from process context, don't
assume preemption is disabled when updating stats
- netfilter: correct length for loading protocol registers
- virtio_net: add checking sq is full inside xdp xmit
- bonding: restore IFF_MASTER/SLAVE flags on bond enslave Ethertype
change
- phy: nxp-c45-tja11xx: fix MII_BASIC_CONFIG_REV bit number
- eth: i40e: fix crash during reboot when adapter is in recovery mode
- eth: ice: avoid deadlock on rtnl lock when auxiliary device
plug/unplug meets bonding
- dsa: mt7530:
- remove now incorrect comment regarding port 5
- set PLL frequency and trgmii only when trgmii is used
- eth: mtk_eth_soc: reset PCS state when changing interface types
Misc:
- ynl: another license adjustment
- move the TCA_EXT_WARN_MSG attribute for tc action"
* tag 'net-6.3-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (108 commits)
selftests: bonding: add tests for ether type changes

ynl: make the tooling check the license
ynl: broaden the license even more

Merge tag 'io_uring-6.3-2023-03-16' of git://git.kernel.dk/linux
Pull io_uring fixes from Jens Axboe:
- When PF_NO_SETAFFINITY was removed for io-wq threads, we kind of
forgot about the SQPOLL thread. Remove it there as well, there's even
less of a reason to set it there (Michal)
- Fixup a confusing 'ret' setting (Li)
- When MSG_RING is used to send a direct descriptor to another ring,
it's possible to have it allocate it on the target ring rather than
provide a specific index for it. If this is done, return the chosen
value in the CQE, like we would've done locally (Pavel)
- Fix a regression in this series on huge page bvec collapsing (Pavel)
* tag 'io_uring-6.3-2023-03-16' of git://git.kernel.dk/linux:
io_uring/rsrc: fix folio accounting
io_uring/msg_ring: let target know allocated index
io_uring: rsrc: Optimize return value variable 'ret'
io_uring/sqpoll: Do not set PF_NO_SETAFFINITY on sqpoll threads
- Fix the psci_pd_init_topology() failure path in the PSCI cpuidle
driver (Shawn Guo).
- Modify the sleepgraph utility so it does not crash on binary data
in device names (Todd Brandt).
