of: module: prevent NULL pointer dereference in vsnprintf()
In of_modalias(), we can get passed the str and len parameters which would cause a kernel oops in vsnprintf() since it only allows passing a NULL ptr when the length is also 0. Also, we need to filter out the negative values of the len parameter as these will result in a really huge buffer since snprintf() takes size_t parameter while ours is ssize_t...

of: dynamic: Synchronize of_changeset_destroy() with the devlink removals
In the following sequence:
1) of_platform_depopulate()
2) of_overlay_remove()
During the step 1, devices are destroyed and devlinks are removed.
During the step 2, OF nodes are destroyed but
__of_changeset_entry_destroy() can raise warnings related to missing
of_node_put():
ERROR: memory leak, expected refcount 1 instead of 2 ...
Indeed, during the devlink removals performed at step 1, the removal
itself releasing the device (and the attached of_node) is done by a job
queued in a workqueue and so, it is done asynchronously with respect to
function calls.
When the warning is present, of_node_put() will be called but wrongly
too late from the workqueue job.
In order to be sure that any ongoing devlink removals are done before
the of_node destruction, synchronize the of_changeset_destroy() with the
devlink removals.

horrible attempt at doing this.)
- kobject lock contention fixes from Eric Dumazet
- driver core cleanups from Andy
- kernfs rcu work from Tejun
- fw_devlink changes to resolve some reported issues
- other minor changes, all details in the shortlog
All of these have been in linux-next for a long time with no reported
issues.

Not a ton of stuff happening in the clk framework in this pull request. We got
some more devm helpers and we seem to be going in the direction of "just turn
this stuff on already and leave me alone!" with the addition of a
devm_clk_bulk_get_all_enable() API. I'm hoping that we can make that into a
genpd that drivers attach instead, but this API should help drivers simplify in
the meantime.
Outside of the devm wrappers, we've got the usual clk driver updates that are
dominated by the major phone SoC vendors (Samsung and Qualcomm) and the
non-critical driver fixes for things like incorrect topology descriptions and
wrong registers or bit fields. More details are below, but I'd say that it
looks pretty ordinary. The only thing that really jumps out at me is the
Renesas clk driver that's ignoring clks that are assigned to remote processors
in DeviceTree. That's a new feature that they're using to avoid marking clks as
CLK_IGNORE_UNUSED based on the configuration of the system.
Core:
- Increase dev_id len for clkdev lookups
- Add a devm_clk_bulk_get_all_enable() API to get and enable all clks
for a device
- Add a devm variant of clk_rate_exclusive_get()
New Drivers:
- Display, TCSR, GPU, and Camera clock controllers for Qualcomm's X1 Elite SoC
- Google GS101 PERIC0 and PERIC1 clock controllers
- Exynos850 PDMA clocks
- Exynos850 CPU cluster 0 and 1 (CMU_CPUCLK0/CMU_CPUCLK1) clock controllers
Removed Drivers:
- Remove the unused Qualcomm sc7180 modem clk driver
Updates:
- Fix some static checker errors in the Hisilicon clk driver
- Polarfire MSSPLL hardware has 4 output clocks (the driver supported
previously only one output); each of these 4 outputs feed dividers and the
output of each divider feed individual hardware blocks (e.g. CAN, Crypto,
eMMC); individual hardware block drivers need to control their clocks thus
clock driver support was added for all MSSPLL output clocks
- Typo fixes in the Qualcomm IPQ5018 GCC driver
- Add "qdss_at" clk on Qualcomm IPQ6018, needed for WiFi
- Properly terminate frequency tables in different Qualcomm clk drivers
- Add MDSS, crypto, and SDCC resets on Qualcomm MSM8953
- Add missing UFS CLKREF clks on Qualcomm SC8180X
- Avoid significant delays during boot by adding a softdep on rpmhpd to
Qualcomm SDM845 gcc driver
- Add QUPv3 RCGS w/ DFS and video resets to Qualcomm SM8150 GCC driver
- Fix the custom GPU GX "do-nothing" method in the Qualcomm GDSC driver
- Add an external regulator to GX GDSC on Qualcomm SC8280XP GPU clk driver
- Switch display, GPU, video, and camera Qualcomm clk drivers to
module_platform_driver()
- Set a longer delay for Venus resets on many Qualcomm SoCs
- Correct the GDSC wait times in the Qualcomm SDM845 display clk driver
- Fix clock listing Oops on Amlogic axg
- New pll-rate for Rockchip rk3568
- i2s rate improvements for Rockchip rk3399
- Rockchip rk3588 syscon clock fixes and removal of overall clock-number from
the rk3588 binding header
- A prerequisite for later improvements to the Rockchip rk3588 linked clocks
- Minor clean-ups and error handling improvements in both composite-8m and SCU
i.MX clock drivers
- Fix for SAI_MCLK_SEL definition for i.MX8MP
- Register the Samsung CMU MISC clock controller earlier, so the Multi Core
Timer clocksource can use it on Google GS101
- Propagate Exynos850 SPI IPCLK rate change to parents, so the SPI will get
proper clock rates
- Refactor the generic Samsung CPU clock controllers code, preparing it for
supporting Exynos850 CPU clocks
- Fix some clk kerneldoc warnings
- Add Ethernet, SDHI, DMA, and HyperFLASH/QSPI (RPC-IF) clocks on Renesas
R-Car V4M
- Ignore all clocks which are assigned to a non-Linux system in the Renesas
clk driver
- Add watchdog clock on Renesas RZ/G3S
- Add camera (CRU) clock and reset on Renesas RZ/G2UL
- Add support for the Renesas R-Car V4M (R8A779H0) SoC
- Convert some clk bindings to YAML so they can be validated

of: Create of_root if no dtb provided by firmware
When enabling CONFIG_OF on a platform where 'of_root' is not populated by firmware, we end up without a root node. In order to apply overlays and create subnodes of the root node, we need one. Create this root node by unflattening an empty builtin dtb. If firmware provides a flattened device tree (FDT) then the FDT is unflattened via setup_arch(). Otherwise, the call to unflatten(_and_copy)?_device_tree() will create an empty root node. We make of_have_populated_dt() return true only if the DTB was loaded by firmware so that existing callers don't change behavior after this patch. The call in the of platform code is removed because it prevents overlays from creating platform devices when the empty root node is used.

of: Always unflatten in unflatten_and_copy_device_tree()
We want to populate an empty DT whenever CONFIG_OF is enabled so that overlays can be applied and the DT unit tests can be run. Make unflatten_and_copy_device_tree() stop printing a warning if the 'initial_boot_params' pointer is NULL. Instead, simply copy the dtb if there is one and then unflatten it. If there isn't a DT to copy, then the call to unflatten_device_tree() is largely a no-op, so nothing really changes here.

of: Add of_machine_compatible_match()
We have of_machine_is_compatible() to check if a machine is compatible with a single compatible string. However some code is able to support multiple compatible boards, and so wants to check for one of many compatible strings. So add of_machine_compatible_match() which takes a NULL terminated array of compatible strings to check against the root node's compatible property. Compared to an open coded match this is slightly more self documenting, and also avoids the caller needing to juggle the root node either directly or via of_find_node_by_path().

of/platform: Inform about created platform devices using pr_debug()
For most nodes with a compatible property a platform device is created. For some an amba device is created instead. For the latter of_amba_device_create() emits a message at debug level about the node the device is created from. Add a similar message to of_platform_device_create_pdata() to inform about the whole list of created devices. This also gives the right context for the following messages that inform about created child devices.

IIO: 1st set of new device support, features and cleanup for 6.9
IIO Backend support =================== New approach from Nuno Sa to the problem of reuse of drivers with IIO devices that are actually the combination of a highspeed chip and an FPGA core handling the data capture and flows. It will hopefully also apply to some other split designs. The ad9467 and axi-adi drivers are converted over to this framework. New device support ================== adi,admfm2000 - New driver for this dual microwave down converter. ams,as73211 - Add support for as7331 UV sensor. richtek,rtq6056 - Add support for related parts RTQ6053 and RTQ6059 st,lsm6dsx - Add ASM330LHHXG1 accelerometer and gyro support (mainly IDs) ti,ads1298 - New driver for this medical ADC. Features ======== tests - Unit tests for the gain-time-scale helper library. bosch,bmi088 - I2C support. bosh,bmi160 - Add 10EC5280 ACPI ID. Used in a number of devices that won't get fixed. The ID is actually a PCI ID belonging to realtech. No response was received to earlier attempts to notify them of this. The manufacturers of some devices have replied to say they will not fix this incorrect ID. Add the ID and hope it isn't a problem. bosch,bmi323 - Add BOSC0200 ACPI ID. Note this is a duplicate of one in the bmc150 driver (it appears these parts share a windows driver). Both drivers perform an ID check that is safe on the other part before successfully probing. hid-sensors-als - Add color temperature and chromaticity support. Note this is a replacement for the series reverted in 6.8 that correctly handles all the potential channel combinations. honeywell,hsc030pa - Triggered buffer support (after driver cleanup). honeywell,mprls00025pa - Improved error handling. - New DT binding to allow use of part number triplet as provided in data sheet to specify equivalent of most of the binding more efficiently. - SPI support. memsic,mxc4005 - ACPI ID MDA6655 as seen in the Chuwi Minibook X 2023 ti,hdc3020 - Add threshold event support (after some driver cleanup) veml,vcnl4000 - Switch to high resolution proximity measurement. Cleanup ======= Various minor typo fixes and better use of defines etc. Treewide - Stop using ACPI_PTR(). The savings in space are small and not worth the complexity of __maybe_unused of ifdef guards. To avoid use in new IIO drivers based on copy and paste, clean it out. - cleanup.h based handling of iio_device_claim_direct_mode()/ iio_device_release_direct_mode() using scope_cond_guard(). In many drivers this is combined with other automated cleanup to give maximum simplifications. An initial set of drivers are converted over to this infrastructure. Tools - Use rewinddir() instead of seekdir() to return to start of file. core - Make iio_bus_type constant. adi,ad16475 - Use irq_get_trigger_type() instead of opencoding. adi,ad16480 - Use irq_get_trigger_type() instead of opencoding. adi,ad-sigma-delta - Avoid overwriting IRQ flags if provided by firmware. ams,as73211 - Use IIO_VAL_FRACTIONAL for scales to simplify the code and potentially improve accuracy. gts-library - Use a div64_u64() instead of a loop to do a division. honeywell,mprls00025pa - Clean up dt-binding doc. - Drop defaults when DT binding not providing values. Very unlikely these were useful given they were wrong for vast majority of supported devices. - Whitespace cleanup miramems,da280 - Use i2c_get_match_data() to replace hand rolled ACPI matching code. semtech,sx9324 - Avoid unnecessary copying of property strings. st,lsm6dsx - Improve docs, particularly wrt to making addition of new device support less noisy. st,lsm9ds0 - Use dev_err_probe() in all probe() error handling. - Improved header includes. - Tidy up termination of ID tables. ti,ads1014 - Correct upper bound on PGA (wrong value had no actual impact) ti,afe4403/4404 - devm_ useage to simplify error handling in probe() and allow() remove to be dropped. voltage-divider - Add dt-binding for io-channel-cells to allow such a device to be both an IIO consumer and IIO producer at the same time. -----BEGIN PGP SIGNATURE----- iQJFBAABCAAvFiEEbilms4eEBlKRJoGxVIU0mcT0FogFAmXXmXERHGppYzIzQGtl cm5lbC5vcmcACgkQVIU0mcT0Foj8Bg/+OZgU0FOEhUXidF58ulMBPTmWG4qBsCCK nB8MhimNn9XcoUDkZwns5ABgRKJvYVqK3VXaGj7HXRcpHzjOAHDCD1aS9EDdwHuo prH9Q5L7iVMhOjKcK3UwtzbUOAjrrmE4Oa74RH4oDLKV9ws6mb1VQfoOgpRNTsTK rA0A3B4W78U+UxLZPWIuYDUS/BgDfSfB024VFtUhMvo0B6G52u6hoDk04//hQuW8 IE0db4VxJLuRDYinBiTbtFtXWO8FNWd8r37MlQKx/llEKtjzI1ZttOK8DyQRudJ7 rLP3nO8svCcQ9oJn0YrnFL9y6PlW/ASUaXH47xBfAiCdKgHlQTf3kDyzwddCqQRD 3cqghbUbYp65Nm1o2TXYQio4zEInS/1ZMzpezb9K1+oiz/xGarjMCR+J4Za4cw76 5jCfnp8vBPDX7JdGwYgbK9nXkXAJ5ewdm7ad03t3oPwfAQPlXfAHIWDT8evNDVlc L94RSmKeMKL1BG3jOr7mJbqIwivf799pgudVJMuBfnlYR+gkBBVvFWhXrgvsJWhQ gKhqfEYCjtJ/t483zcJporvWBmmmf6gUvNOB4x6oA0j85GPGoDlTdfK54dkD+98k KP83Wd4LqDOM6V6PE+L7yTW05sOgT2qDHYrw/qAPoEogThSSCoqRm/kWwPBv3toL 0ykQId5/UBk= =xkgf -----END PGP SIGNATURE----- Merge tag 'iio-for-6.9a' of http://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Jonathan writes: IIO: 1st set of new device support, features and cleanup for 6.9 IIO Backend support =================== New approach from Nuno Sa to the problem of reuse of drivers with IIO devices that are actually the combination of a highspeed chip and an FPGA core handling the data capture and flows.

Char/Misc and other Driver changes for 6.8-rc1
Here is the big set of char/misc and other driver subsystem changes for 6.8-rc1.

of: Fix double free in of_parse_phandle_with_args_map
In of_parse_phandle_with_args_map() the inner loop that
iterates through the map entries calls of_node_put(new)
to free the reference acquired by the previous iteration
of the inner loop. This assumes that the value of "new" is
NULL on the first iteration of the inner loop.
Make sure that this is true in all iterations of the outer
loop by setting "new" to NULL after its value is assigned to "cur".
Extend the unittest to detect the double free and add an additional
test case that actually triggers this path.
Fixes:

of: device: Export of_device_make_bus_id()
This helper is really handy to create unique device names based on their device tree path, we may need it outside of the OF core (in the NVMEM subsystem) so let's export it. As this helper has nothing patform specific, let's move it to of/device.c instead of of/platform.c so we can add its prototype to of_device.h.

iommu: Remove struct iommu_ops *iommu from arch_setup_dma_ops()
This is not being used to pass ops, it is just a way to tell if an iommu driver was probed. These days this can be detected directly via device_iommu_mapped(). Call device_iommu_mapped() in the two places that need to check it and remove the iommu parameter everywhere.
