cb13aa16f3 i2c: meson: Fix wrong speed use from probe
Having meson_i2c_set_clk_div after i2c_add_adapter
causes issues for client drivers that try to use
the bus before the requested speed is applied.

The bus can be used just after i2c_add_adapter, so
move i2c_add_adapter to the final step as
meson_i2c_set_clk_div needs to be called before
the bus is used.

d714fb25e7 i2c: add tracepoints for I2C slave events
I2C slave events tracepoints can be enabled by:

	echo 1 > /sys/kernel/tracing/events/i2c_slave/enable

and logs in /sys/kernel/tracing/trace will look like:

	... i2c_slave: i2c-0 a=010 ret=0 WR_REQ []
	... i2c_slave: i2c-0 a=010 ret=0 WR_RCV [02]
	... i2c_slave: i2c-0 a=010 ret=0 WR_RCV [0c]
	... i2c_slave: i2c-0 a=010 ret=0   STOP []
	... i2c_slave: i2c-0 a=010 ret=0 RD_REQ [04]
	... i2c_slave: i2c-0 a=010 ret=0 RD_PRO [b4]
	... i2c_slave: i2c-0 a=010 ret=0  STOP []

formatted as:

	i2c-<adapter_nr>
	a=<addr>
	ret=<ret>	<- callback return value
	<event>
	[<data>]

trace printings can be selected by adding a filter like:

246313e313 MAINTAINERS: adjust XLP9XX I2C DRIVER after removing the devicetree binding
Commit 0e5f897708 ("dt-bindings: Remove Netlogic bindings") removes the
devicetree binding i2c-xlp9xx.txt, but misses to adjust the reference in
MAINTAINERS.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken reference.

Remove the file reference to i2c-xlp9xx.txt in XLP9XX I2C DRIVER.

As commit ef99066c7d ("i2c: Remove Netlogic XLP variant") explains, the
i2c-xlp9xx driver is still used by the Cavium ThunderX2 platform. So, keep
the XLP9XX I2C DRIVER section in MAINTAINERS with its reference to
drivers/i2c/busses/i2c-xlp9xx.c.

When CONFIG_PM is set but CONFIG_PM_SLEEP is not, two compiler warnings

             ^
  2 errors generated.

These functions are only used in SET_LATE_SYSTEM_SLEEP_PM_OPS(), which
is defined as empty when CONFIG_PM_SLEEP is not defined. Mark the
functions as __maybe_unused to make it clear that these functions might
be unused in this configuration.

Since depending on the SoC or specific bus functionality some clocks
may be optional, we cannot get the benefit of using devm_clk_bulk_get()
but, by migrating to clk-bulk, we are able to remove the custom functions
mtk_i2c_clock_enable() and mtk_i2c_clock_disable(), increasing common
APIs usage, hence (lightly) decreasing kernel footprint.

1d366c2f9d i2c: xiic: Make bus names unique
This driver is for an FPGA logic core, so there can be arbitrarily many
instances of the bus on a given system. Previously all of the I2C bus
names were "xiic-i2c" which caused issues with lm_sensors when trying to
map human-readable names to sensor inputs because it could not properly
distinguish the busses, for example. Append the platform device name to
the I2C bus name so it is unique between different instances.

9c02c6391c i2c: i801: Drop useless masking in i801_access
I went all the way back to kernel 2.6.12 and that masking was never
needed. I suppose it was there in anticipation of software PEC
support, but that was never added to the driver (and never will be,
as this is made obsolete by hardware PEC).

I'm also removing initialization to 0, which is not needed either,
and would prevent the compiler from reporting an actual usage of
uninitialized variables.

c57813b8b2 i2c: designware: Lock the adapter while setting the suspended flag
Lock the adapter while setting the suspended flag, to ensure that other
locked code always sees the change immediately, rather then possibly using
a stale value.

This involves splitting the suspend/resume callbacks into separate runtime
and normal suspend/resume calls. This is necessary because i2c_dw_xfer()
will get called by the i2c-core with the adapter locked and it in turn
calls the runtime-resume callback through pm_runtime_get_sync().

So the runtime versions of the suspend/resume callbacks cannot take
the adapter-lock. Note this patch simply makes the runtime suspend/resume
callbacks not deal with the suspended flag at all. During runtime the
pm_runtime_get_sync() from i2c_dw_xfer() will always ensure that the
adapter is resumed when necessary.

The suspended flag check is only necessary to check proper suspend/resume
ordering during normal suspend/resume which makes the pm_runtime_get_sync()
call a no-op.

17ba1e87fc i2c: designware: Fix improper usage of readl
Kernel test robot reported incorrect type in argument 1 of readl(), but
more importantly it brought attention that MMIO accessor shouldn't be
used in this case, since req->hdr.status is part of a command-response
buffer in system memory.

Since its value may be altered by PSP outside of the scope of current
thread (somehow similar to IRQ handler case), we need to use
READ_ONCE() to ensure compiler won't optimize this call.

Fix also 'status' variable type to reflect that corresponding field in
command-response buffer is platform-independent u32.

da2e86c0bd i2c: riic: Simplify reset handling
Read reset phandle as optional instead of exclusive so that all the DT's
passing the reset phandle can be used to assert/deassert the reset line.
With this change we don't have to differentiate the RZ/G2L SoC.

With the above changes we no longer need the "renesas,riic-r9a07g044"
compatible string, so drop it from riic_i2c_dt_ids[]. No changes are
required to the r9a07g044.dtsi as we already have "renesas,riic-rz" as a
fallback compatible string.

While at it, check the return code of reset_control_deassert() as it might
fail and also add a devres action to assert the reset line.

Merge tag 'pidfd.v5.17-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux

Pull pidfd fix from Christian Brauner:
 "This fixes a problem reported by lockdep when installing a pidfd via
  fd_install() with siglock and the tasklisk write lock held in
  copy_process() when calling clone()/clone3() with CLONE_PIDFD.

  Originally a pidfd was created prior to holding any of these locks but
  this required a call to ksys_close(). So quite some time ago in
  6fd2fe494b ("copy_process(): don't use ksys_close() on cleanups") we
  switched to a get_unused_fd_flags() + fd_install() model.

  As part of that we moved fd_install() as late as possible. This was
  done for two main reasons. First, because we needed to ensure that we
  call fd_install() past the point of no return as once that's called
  the fd is live in the task's file table. Second, because we tried to
  ensure that the fd is visible in /proc/<pid>/fd/<pidfd> right when the
  task is visible.

  This fix moves the fd_install() to an even later point which means
  that a task will be visible in proc while the pidfd isn't yet under
  /proc/<pid>/fd/<pidfd>.

  While this is a user visible change it's very unlikely that this will
  have any impact. Nobody should be relying on that and if they do we
  need to come up with something better but again, it's doubtful this is
  relevant"

Pull ucounts fixes from Eric Biederman:
 "Michal Koutný recently found some bugs in the enforcement of
  RLIMIT_NPROC in the recent ucount rlimit implementation.

  In this set of patches I have developed a very conservative approach
  changing only what is necessary to fix the bugs that I can see
  clearly. Cleanups and anything that is making the code more consistent
  can follow after we have the code working as it has historically.

  The problem is not so much inconsistencies (although those exist) but
  that it is very difficult to figure out what the code should be doing
  in the case of RLIMIT_NPROC.

  All other rlimits are only enforced where the resource is acquired
  (allocated). RLIMIT_NPROC by necessity needs to be enforced in an
  additional location, and our current implementation stumbled it's way
  into that implementation"

Where commit 4ef0c5c6b5 ("kernel/sched: Fix sched_fork() access an
invalid sched_task_group") fixed a fork race vs cgroup, it opened up a
race vs syscalls by not placing the task on the runqueue before it
gets exposed through the pidhash.

Commit 13765de814 ("sched/fair: Fix fault in reweight_entity") is
trying to fix a single instance of this, instead fix the whole class
of issues, effectively reverting this commit.

Pull ACPI fixes from Rafael Wysocki:
 "These make an excess warning message go away and fix a recently
  introduced boot failure on a vintage machine.

  Specifics:

   - Change the log level of the "table not found" message in
     acpi_table_parse_entries_array() to debug to prevent it from
     showing up in the logs unnecessarily (Dan Williams)

   - Add a C-state limit quirk for 32-bit ThinkPad T40 to prevent it
     from crashing on boot after recent changes in the ACPI processor
     driver (Woody Suwalski)"

7b1f781f2d Input: psmouse - set up dependency between PS/2 and SMBus companions
When we switch from emulated PS/2 to native (RMI4 or Elan) protocols, we
create SMBus companion devices that are attached to I2C/SMBus controllers.
However, when suspending and resuming, we also need to make sure that we
take into account the PS/2 device they are associated with, so that PS/2
device is suspended after the companion and resumed before it, otherwise
companions will not work properly. Before I2C devices were marked for
asynchronous suspend/resume, this ordering happened naturally, but now we
need to enforce it by establishing device links, with PS/2 devices being
suppliers and SMBus companions being consumers.

Fixes: 172d931910 ("i2c: enable async suspend/resume on i2c client devices")
