Char/Misc/IIO pull request for 6.16-rc1
Here is the big char/misc/iio and other small driver subsystem pull
request for 6.16-rc1.
Overall, a lot of individual changes, but nothing major, just the normal
constant forward progress of new device support and cleanups to existing
subsystems. Highlights in here are:
- Large IIO driver updates and additions and device tree changes
- Android binder bugfixes and logfile fixes
- mhi driver updates
- comedi driver updates
- counter driver updates and additions
- coresight driver updates and additions
- echo driver removal as there are no in-kernel users of it
- nvmem driver updates
- spmi driver updates
- new amd-sbi driver "subsystem" and drivers added
- rust miscdriver binding documentation fix
- other small driver fixes and updates (uio, w1, acrn, hpet, xillybus,
cardreader drivers, fastrpc and others.)
All of these have been in linux-next for quite a while with no reported
problems.

ARM: soc updates for 6.16
The main update in size is the removal of the TI DaVinci DA830 SoC support. DA830 is similar to DA850, which remain supported, but only the reference board was ever supported, and we removed that one 3 years ago as it had never been converted to devicetree. There are some other cleanups for OMAP4 and a few boards using old GPIO interfaces. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmg532EACgkQmmx57+YA GNk1Wg/+LyNX9SX/OrHa0mIv8MpVd+JqJQccFRQ1M9Yt53xPbG+7iToQkRicMS6+ 1dUPypjt9dSh8dTxwZ4zMEZ/x6Pg8j5CxW74ye0s5ympq/EFCab07DTayZUmj0XL C2NDpCTec47uD8BjAf03wdsw34Qd5I9JIjWXoWo9o4MtUHenaMn86TCuCdWyclMi 8JZLnyW+D+K2u1LAmh43L9JidHYCd90N6gDKpcWL37FrEcJR+8AI8XLNWViyOEq2 ow7aj5KTtcmChslgxMtQcxOJ32g0u3RAUdf24OrptYA0RfYmxzscyWoTpCWYket6 H9xnrz+OHejabVRa484FeHSQRRRgwdNR8eAKNs/NQIf5SM/SWuQy8vQu9wJEA9gm 2iNF6c4vSl65xu/LwamlkIMBEM7XY+ABtkJ63LaLHQaQ2NB7Cc8OebQXRhUNS6Dm tdTdFz5aw+vN1r6zobQ3Lk4DpA0SUueTHOc9GYXdp0piKANWTUL/oYBEVR10gSto vtUOWHUeoeaTffqWTJvOXq9YsXOAk71bBHa+uqrYz2Q12zuohWfB82uPU4jgiWAK SaMCo27HKmTdEctzA0fSEfel26C4SephMmu7QiCtGgwCnR6F1nlztyjjYVzt5DtZ t9iXXIk8K5B7W7WARU8DnSQFHgc49SowbRhrV0EpC4j2grs8Ix0= =8hph -----END PGP SIGNATURE----- Merge tag 'soc-arm-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM SoC updates from Arnd Bergmann: "The main update in size is the removal of the TI DaVinci DA830 SoC support.

bus: moxtet: Switch to irq_domain_create_simple()
irq_domain_add_simple() is going away as being obsolete now. Switch to the preferred irq_domain_create_simple(). That differs in the first parameter: It takes more generic struct fwnode_handle instead of struct device_node. Therefore, of_fwnode_handle() is added around the parameter. Note some of the users can likely use dev->fwnode directly instead of indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not guaranteed to be set for all, so this has to be investigated on case to case basis (by people who can actually test with the HW).

bus: mhi: host: Fix conflict between power_up and SYSERR
When mhi_async_power_up() enables IRQs, it is possible that we could
receive a SYSERR notification from the device if the firmware has crashed
for some reason. Then the SYSERR notification queues a work item that
cannot execute until the pm_mutex is released by mhi_async_power_up().
So the SYSERR work item will be pending. If mhi_async_power_up() detects
the SYSERR, it will handle it. If the device is in PBL, then the PBL state
transition event will be queued, resulting in a work item after the
pending SYSERR work item. Once mhi_async_power_up() releases the pm_mutex,
the SYSERR work item can run. It will blindly attempt to reset the MHI
state machine, which is the recovery action for SYSERR. PBL/SBL are not
interrupt driven and will ignore the MHI Reset unless SYSERR is actively
advertised. This will cause the SYSERR work item to timeout waiting for
reset to be cleared, and will leave the host state in SYSERR processing.
The PBL transition work item will then run, and immediately fail because
SYSERR processing is not a valid state for PBL transition.
This leaves the device uninitialized.
This issue has a fairly unique signature in the kernel log:
mhi mhi3: Requested to power ON
Qualcomm Cloud AI 100 0000:36:00.0: Fatal error received from
device. Attempting to recover
mhi mhi3: Power on setup success
mhi mhi3: Device failed to exit MHI Reset state
mhi mhi3: Device MHI is not in valid state
We cannot remove the SYSERR handling from mhi_async_power_up() because the
device may be in the SYSERR state, but we missed the notification as the
irq was fired before irqs were enabled. We also can't queue the SYSERR work
item from mhi_async_power_up() if SYSERR is detected because that may
result in a duplicate work item, and cause the same issue since the
duplicate item will blindly issue MHI reset even if SYSERR is no longer
active.
Instead, add a check in the SYSERR work item to make sure that MHI reset is
only issued if the device is in SYSERR state for PBL or SBL EEs.

bus: fsl-mc: Use strscpy() instead of strscpy_pad()
Both destination buffers are already zero-initialized, making strscpy() sufficient for safely copying 'obj_type'. The additional NUL-padding performed by strscpy_pad() is unnecessary. If the destination buffer has a fixed length, strscpy() automatically determines its size using sizeof() when the argument is omitted. This makes the explicit size arguments unnecessary. No functional changes intended.

bus: fsl_mc: Fix driver_managed_dma check
Since it's not currently safe to take device_lock() in the IOMMU probe
path, that can race against really_probe() setting dev->driver before
attempting to bind. The race itself isn't so bad, since we're only
concerned with dereferencing dev->driver itself anyway, but sadly my
attempt to implement the check with minimal churn leads to a kind of
TOCTOU issue, where dev->driver becomes valid after to_fsl_mc_driver(NULL)
is already computed, and thus the check fails to work as intended.
Will and I both hit this with the platform bus, but the pattern here is
the same, so fix it for correctness too.

bus: fsl-mc: do not add a device-link for the UAPI used DPMCP device
The fsl-mc bus associated to the root DPRC in a DPAA2 system exports a
device file for userspace access to the MC firmware. In case the DPRC's
local MC portal (DPMCP) is currently in use, a new DPMCP device is
allocated through the fsl_mc_portal_allocate() function.
In this case, the call to fsl_mc_portal_allocate() will fail with -EINVAL
when trying to add a device link between the root DPRC (consumer) and
the newly allocated DPMCP device (supplier). This is because the DPMCP
is a dependent of the DPRC device (the bus).
Fix this by not adding a device link in case the DPMCP is allocated for
the root DPRC's usage.

bus: fsl-mc: fix double-free on mc_dev
The blamed commit tried to simplify how the deallocations are done but,
in the process, introduced a double-free on the mc_dev variable.
In case the MC device is a DPRC, a new mc_bus is allocated and the
mc_dev variable is just a reference to one of its fields. In this
circumstance, on the error path only the mc_bus should be freed.
This commit introduces back the following checkpatch warning which is a
false-positive.
WARNING: kfree(NULL) is safe and this check is probably not required
+ if (mc_bus)
+ kfree(mc_bus);

bus: mhi: ep: Update read pointer only after buffer is written
Inside mhi_ep_ring_add_element, the read pointer (rd_offset) is updated
before the buffer is written, potentially causing race conditions where
the host sees an updated read pointer before the buffer is actually
written. Updating rd_offset prematurely can lead to the host accessing
an uninitialized or incomplete element, resulting in data corruption.
Invoke the buffer write before updating rd_offset to ensure the element
is fully written before signaling its availability.

Pull drm updates from Dave Airlie:
"Outside of drm there are some rust patches from Danilo who maintains
that area in here, and some pieces for drm header check tests.
The major things in here are a new driver supporting the touchbar
displays on M1/M2, the nova-core stub driver which is just the vehicle
for adding rust abstractions and start developing a real driver inside
of.
xe adds support for SVM with a non-driver specific SVM core
abstraction that will hopefully be useful for other drivers, along
with support for shrinking for TTM devices. I'm sure xe and AMD
support new devices, but the pipeline depth on these things is hard to
know what they end up being in the marketplace!

bus: mhi: host: Fix race between unprepare and queue_buf
A client driver may use mhi_unprepare_from_transfer() to quiesce
incoming data during the client driver's tear down. The client driver
might also be processing data at the same time, resulting in a call to
mhi_queue_buf() which will invoke mhi_gen_tre(). If mhi_gen_tre() runs
after mhi_unprepare_from_transfer() has torn down the channel, a panic
will occur due to an invalid dereference leading to a page fault.
This occurs because mhi_gen_tre() does not verify the channel state
after locking it. Fix this by having mhi_gen_tre() confirm the channel
state is valid, or return error to avoid accessing deinitialized data.

bus: qcom-ssc-block-bus: Fix the error handling path of qcom_ssc_block_bus_probe()
If qcom_ssc_block_bus_pds_enable() fails, the previous call to
qcom_ssc_block_bus_pds_attach() must be undone, as already done in the
remove function.
In order to do that, move the code related to the power domains management
to the end of the function, in order to avoid many changes in all the error
handling path that would need to go through the new error handling path.

iommu: Get DT/ACPI parsing into the proper probe path
In hindsight, there were some crucial subtleties overlooked when moving
{of,acpi}_dma_configure() to driver probe time to allow waiting for
IOMMU drivers with -EPROBE_DEFER, and these have become an
ever-increasing source of problems. The IOMMU API has some fundamental
assumptions that iommu_probe_device() is called for every device added
to the system, in the order in which they are added. Calling it in a
random order or not at all dependent on driver binding leads to
malformed groups, a potential lack of isolation for devices with no
driver, and all manner of unexpected concurrency and race conditions.
We've attempted to mitigate the latter with point-fix bodges like
iommu_probe_device_lock, but it's a losing battle and the time has come
to bite the bullet and address the true source of the problem instead.
The crux of the matter is that the firmware parsing actually serves two
distinct purposes; one is identifying the IOMMU instance associated with
a device so we can check its availability, the second is actually
telling that instance about the relevant firmware-provided data for the
device. However the latter also depends on the former, and at the time
there was no good place to defer and retry that separately from the
availability check we also wanted for client driver probe.
Nowadays, though, we have a proper notion of multiple IOMMU instances in
the core API itself, and each one gets a chance to probe its own devices
upon registration, so we can finally make that work as intended for
DT/IORT/VIOT platforms too. All we need is for iommu_probe_device() to
be able to run the iommu_fwspec machinery currently buried deep in the
wrong end of {of,acpi}_dma_configure(). Luckily it turns out to be
surprisingly straightforward to bootstrap this transformation by pretty
much just calling the same path twice. At client driver probe time,
dev->driver is obviously set; conversely at device_add(), or a
subsequent bus_iommu_probe(), any device waiting for an IOMMU really
should *not* have a driver already, so we can use that as a condition to
disambiguate the two cases, and avoid recursing back into the IOMMU core
at the wrong times.
Obviously this isn't the nicest thing, but for now it gives us a
functional baseline to then unpick the layers in between without many
more awkward cross-subsystem patches. There are some minor side-effects
like dma_range_map potentially being created earlier, and some debug
prints being repeated, but these aren't significantly detrimental. Let's
make things work first, then deal with making them nice.
With the basic flow finally in the right order again, the next step is
probably turning the bus->dma_configure paths inside-out, since all we
really need from bus code is its notion of which device and input ID(s)
to parse the common firmware properties with...

bus: mhi: host: Avoid possible uninitialized fw_load_type
If mhi_fw_load_handler() bails out early because the EE is not capable
of loading firmware, we may reference fw_load_type in cleanup which is
uninitialized at this point. The cleanup code checks fw_load_type as a
proxy for knowing if fbc_image was allocated and needs to be freed, but
we can directly test for that. This avoids the possible uninitialized
access and appears to be clearer code.

bus: simple-pm-bus: fix forced runtime PM use
The simple-pm-bus driver only enables runtime PM for some buses
('simple-pm-bus') yet has started calling pm_runtime_force_suspend() and
pm_runtime_force_resume() during system suspend unconditionally.
This currently works, but that is not obvious and depends on
implementation details which may change at some point.
Add dedicated system sleep ops and only call pm_runtime_force_suspend()
and pm_runtime_force_resume() for buses that use runtime PM to avoid any
future surprises.

bus: mhi: host: pci_generic: Use pci_try_reset_function() to avoid deadlock
There are multiple places from where the recovery work gets scheduled
asynchronously. Also, there are multiple places where the caller waits
synchronously for the recovery to be completed. One such place is during
the PM shutdown() callback.
If the device is not alive during recovery_work, it will try to reset the
device using pci_reset_function(). This function internally will take the
device_lock() first before resetting the device. By this time, if the lock
has already been acquired, then recovery_work will get stalled while
waiting for the lock. And if the lock was already acquired by the caller
which waits for the recovery_work to be completed, it will lead to
deadlock.
This is what happened on the X1E80100 CRD device when the device died
before shutdown() callback. Driver core calls the driver's shutdown()
callback while holding the device_lock() leading to deadlock.
And this deadlock scenario can occur on other paths as well, like during
the PM suspend() callback, where the driver core would hold the
device_lock() before calling driver's suspend() callback. And if the
recovery_work was already started, it could lead to deadlock. This is also
observed on the X1E80100 CRD.
So to fix both issues, use pci_try_reset_function() in recovery_work. This
function first checks for the availability of the device_lock() before
trying to reset the device. If the lock is available, it will acquire it
and reset the device. Otherwise, it will return -EAGAIN. If that happens,
recovery_work will fail with the error message "Recovery failed" as not
much could be done.

With this policy, BHIe will be used to transfer firmware in PBL if the MHI controller has BHIe regs, sets seg_len, and does not set fbc_download.

Driver core and debugfs updates
Here is the big set of driver core and debugfs updates for 6.14-rc1.
It's coming late in the merge cycle as there are a number of merge
conflicts with your tree now, and I wanted to make sure they were
working properly. To resolve them, look in linux-next, and I will send
the "fixup" patch as a response to the pull request.
Included in here is a bunch of driver core, PCI, OF, and platform rust
bindings (all acked by the different subsystem maintainers), hence the
merge conflict with the rust tree, and some driver core api updates to
mark things as const, which will also require some fixups due to new
stuff coming in through other trees in this merge window.
There are also a bunch of debugfs updates from Al, and there is at least
one user that does have a regression with these, but Al is working on
tracking down the fix for it. In my use (and everyone else's linux-next
use), it does not seem like a big issue at the moment.
Here's a short list of the things in here:
- driver core bindings for PCI, platform, OF, and some i/o functions.
We are almost at the "write a real driver in rust" stage now,
depending on what you want to do.
- misc device rust bindings and a sample driver to show how to use
them
- debugfs cleanups in the fs as well as the users of the fs api for
places where drivers got it wrong or were unnecessarily doing things
in complex ways.
- driver core const work, making more of the api take const * for
different parameters to make the rust bindings easier overall.
- other small fixes and updates
All of these have been in linux-next with all of the aforementioned
merge conflicts, and the one debugfs issue, which looks to be resolved
"soon".
