Merge tag 'mhi-for-v6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/mani/mhi into char-misc-next Manivannan writes: MHI Host ======== - Added new MHI_PM_SYS_ERR_FAIL state to the MHI state machine to properly cleanup the channel state if the device fails to respond to the MHI reset during SYS_ERR handling. This issue was discovered with the Qualcomm AIC100 AI accelerator device. - Modified the code that reads and exposes the OEM_PK_HASH registers through sysfs to read them on-demand instead of reading once during boot. Qualcomm AIC100 devices support provisioning the keys dynamically, so this allows the users to know the upto date information. - Added tracepoint support to expose the debug information over tracefs. - Reverted the commit that reads the MHI device revision from the device during boot. This is done because the read info was not used anywhere (dead code) and also it is not possible to read the revision info from all the devices. - Constified the modem config for Telit FN980 modem as required by the MHI core. MHI Endpoint ============ - Replaced kzalloc() with kcalloc() in an effort to avoid integer overflows during multiplication. Even though there is no potential overflow in the endpoint code, this is done for the sake of uniformity and best practice. - Fixed the kmem_cache_create() failure check to use the correct variable. * tag 'mhi-for-v6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/mani/mhi: bus: mhi: host: pci_generic: constify modem_telit_fn980_hw_v1_config bus: mhi: host: Change the trace string for the userspace tools mapping bus: mhi: ep: check the correct variable in mhi_ep_register_controller() Revert "bus: mhi: core: Add support for reading MHI info from device" bus: mhi: host: Add tracing support bus: mhi: ep: Use kcalloc() instead of kzalloc() bus: mhi: host: Read PK HASH dynamically bus: mhi: host: Add MHI_PM_SYS_ERR_FAIL state

The unit for TPDM DSB element size is bits. So rename the property: qcom,dsb-element-size => qcom,dsb-element-bits This also makes it consistent with the naming for the CMB element size property.

When perf_init_event() calls perf_try_init_event() to init pmu driver, searches for the next pmu driver only when the return value is -ENOENT. Therefore, hisi_ptt_pmu_event_init() needs to check the type at the beginning of the function. Otherwise, in the case of perf-task mode, perf_try_init_event() returns -EOPNOTSUPP and skips subsequent pmu drivers, causes perf_init_event() to fail.

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. 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. * tag 'iio-for-6.9a' of http://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (106 commits) iio: imu: bmi323: Add ACPI Match Table iio: accel: bmc150: Document duplicate ACPI entries with bmi323 driver iio: adc: ti-ads1298: Add driver dt-bindings: iio: adc: ti-ads1298: Add bindings iio: pressure: hsc030pa add triggered buffer iio: pressure: hsc030pa add mandatory delay iio: pressure: hsc030pa: update datasheet URLs iio: pressure: hsc030pa: include cleanup iio: pressure: hsc030pa: use signed type to hold div_64() result dt-bindings: iio: pressure: honeywell,hsc030pa.yaml add spi props iio: st_sensors: lsm9ds0: Use common style for terminator in ID tables iio: st_sensors: lsm9ds0: Don't use "proxy" headers iio: st_sensors: lsm9ds0: Use dev_err_probe() everywhere iio: adc: adi-axi-adc: move to backend framework iio: adc: ad9467: convert to backend framework iio: add the IIO backend framework iio: buffer-dmaengine: export buffer alloc and free functions of: property: add device link support for io-backends dt-bindings: adc: axi-adc: update bindings for backend framework dt-bindings: adc: ad9467: add new io-backend property ...

This reverts commit 3316ab2b. The MHI spec owner pointed out that the SOC_HW_VERSION register is part of the BHIe segment, and only valid on devices which implement BHIe. Only a small subset of MHI devices implement BHIe so blindly accessing the register for all devices is not correct. Also, since the BHIe segment offset is not used when accessing the register, any implementation which moves the BHIe segment will result in accessing some other register. We've seen that accessing this register on AIC100 which does not support BHIe can result in initialization failures. We could try to put checks into the code to address these issues, but in the roughly 4 years this functionality has existed, no one has used it. Easier to drop this dead code and address the issues if anyone comes up with a real world use for it. Signed-off-by:

Convert the driver to use the new IIO backend framework. The device functionality is expected to be the same (meaning no added or removed features). Also note this patch effectively breaks ABI and that's needed so we can properly support this device and add needed features making use of the new IIO framework. Given the lack of features (and devices supported) in the ad9467 driver compared with the ADI out of tree version, we don't expect any user of the upstream driver so no one should notice the ABI breakage. However, if someone is affected by this, ADI will happily support transitioning to the backend framework. Signed-off-by:

This is a Framework to handle complex IIO aggregate devices. The typical architecture is to have one device as the frontend device which can be "linked" against one or multiple backend devices. All the IIO and userspace interface is expected to be registers/managed by the frontend device which will callback into the backends when needed (to get/set some configuration that it does not directly control). The basic framework interface is pretty simple: - Backends should register themselves with @devm_iio_backend_register() - Frontend devices should get backends with @devm_iio_backend_get() Signed-off-by:

Export iio_dmaengine_buffer_free() and iio_dmaengine_buffer_alloc(). This is in preparation of introducing IIO backends support. This will allow us to allocate a buffer and control it's lifetime from a device different from the one holding the DMA firmware properties. Effectively, in this case the struct device holding the firmware information about the DMA channels is not the same as iio_dev->dev.parent (typical case). While at it, namespace the buffer-dmaengine exports and update the current user of these buffers. Signed-off-by:

'adi,adc-dev' is now deprecated and must not be used anymore. Hence, also remove it from being required. The reason why it's being deprecated is because the axi-adc CORE is now an IIO service provider hardware (IIO backends) for consumers to make use of. Before, the logic with 'adi,adc-dev' was the opposite (it was kind of consumer referencing other nodes/devices) and that proved to be wrong and to not scale. Now, IIO consumers of this hardware are expected to reference it using the io-backends property. Hence, the new '#io-backend-cells' is being added so the device is easily identified as a provider.
