ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Pull IIO updaate from Jonathan: IIO: 1st set of new device support, features and cleanup for 6.14 Fairly quiet cycle. Usual mix of new drivers, device support in existing drivers, features and more general rework and cleanup. There are a few late breaking or long standing but complex fixes in here as well. There is one expected merge conflict due to an upstream fix touching neighboring code in ti-ads1119. The trivial resolution is the right one with the result ending up as: struct { s16 sample; aligned_s64 timestamp; } scan; New device support ================== adi,ad4000 - Add support for many Pulsar ADC devices: AD7685, AD7686, AD7687, AD7688, AD7690, AD7691, AD7693, AD7942, AD7946, AD7980, AD7982, AD7983, AD7984, AD7988-1 and AD7988-5 ADCs. Generally similar to the AD4000 series but with lower sampling rates and no configuration registers. Includes addition of timestamp channels. adi,adis16480 - Add support for ADIS16486, ADIS16487 and ADIS16489 IMUs. Required a few tweaks to existing driver and addition of tables. kionix,kx022a - Add support for KX134ACR-LBZ accelerometer that is similar to the KX132ACR-LBZ but with a wider (+-64G) sensor range. - Add support for KX134-1211 accelerometer that is similar to the KX132-1211 but with a wider (+-16G) sensor range. nxp,fxls8962af - Add support for fxls8974cf and fxls8967af accelerometers, Both are compatible with fxls8962af but with different device IDs which are used in presence checks. renesas,rzg2l - Add support for Renesas RZ/GS3 SoC ADCs (various driver refactors precede this to allow for chip differences). rohm,bd79704 - New driver for this 6 channel DAC. st,mpu6050 - Support he IAM20380 which is effectively a cut down IAM20608 IMU with only a gyroscope (no accelerometer). st,stm-timmer-trigger - Add support for ADC trigger use case for the STM32MP25 SOC. Do not support the counter functionality in this driver as that is handled by the counter subsystem. ti,opt4060 - New driver for this RGBW color sensor. Driver drop =========== rohm,bu20008 - Drop as decision was made to not mass produce this light sensor after Matti had done all the work to get a driver upstream. Features ======== adi,ad_sigma_delta library + ad7124 - Allow for GPIO to check interrupt status, enabling this device on more platforms that don't obey prior (non general) assumptions on how the interrupt chips work. - Allow variation in reset sequence length allowing chip specific optimizations rather than always using worst case. adi,ad7124 - Add temperature channel support. adi,ad7173 - Add support calibration modes for this family of ADCs. adi,adxl345 - Binding update to allow specification of which interrupt line is connected (or none). - Support interrupts and FIFO based data capture. bosch,bme680 - Add regulators support. Note this required a new binding doc rather than use of trivial-devices - Runtime PM support. microchip,pac1921 - Add ACPI support including _DSM for shunt value and label. renesas,rzg2l - Enable runtime autosuspend. - Add suspend and resume support. tyhx,hx9023s - Add loading of a firmware file used to set defaults for some configuration registers. vishay,veml6030 - Support triggered buffers allowing efficient data capture at higher speeds. - Add regmap cache to reduce access to device. Cleanup and minor fixes ======================= cross-tree - Another batch of conversions to devm_regulator_get_enable_read_voltage() helper and related conversions to full devm that this enables. - Various patches using guard() to allow early returns and simpler code flow. - Various conversions from s64 timestamp __aligned(8) to aligned_s64 type. Includes a few cleanups where this unsigned and it should have been signed. - Fix up some missing types for drive-open-drain in dt-binding docs. core - Add missing documentation for iio_dmaengine_buffer_setup_ext() - Add check that all buffers passed to iio_read_channel_ext_info() and iio_read_channel_label() are page sized and page aligned. Done this way because the callbacks are almost always only used to fill sysfs attributes. The check covers the tiny percentage of cases where use is made of this data in a consumer driver. - Mark scan_timestamp memory of struct iio_dev private ensuring no drivers change the value which belongs to the IIO core. documentation - Various missing ABI docs added. - ABI docs made to use Y consistently as the wildcard for channel number. - Combine duplicate in_currentY_raw entries in ABI docs. iio-mux - Fix alignment of buffers passed to iio_channel_read_ext_info(). adi,ad_sigma_delta library - Respect keep_cs_asserted flag in read path. - Close a race condition around irq enabling and disabling. - Use explicit unsigned int in place of unsigned. adi,ad6695 - Move dt-binding header under adc sub-directory and fix include path in dt example. adi,ad7124 - Check number of channels in DT doesn't exceed what the driver can handle. - Check input specified in DT are possible. - Improved error reporting during probe. adi,ad7173 - Drop unused structure element. adi,ad7293 - Ensure power is turned on before resetting. adi,adxl345 - Some documentation simplification and parameter renames. - Add a function than unifies handling of power up and power down. - Add defines to have a complete set of registers defined. - Add missing \n to end of error messages. amlogic,meson_saradc - Simplify handling of the REG11 register access. awinic,aw96104 - Constify iio_info structure. bosch,bmp085 - Add to dt-binding to indicate devices support SPI. bosch,bmp280 - Use sizeof() to replace a somewhat magic 2. - Rename sleep related variables so the unit is included and use fsleep() to replace usleep_range() calls. bosch,bno055 - Constify struct bin_attribute capella,cm3232 - Reset device before checking hardware ID inline with suggested flow from datasheet. diolan,dln2 - Simplify zeroing of structure used to gather up data by just clearing the whole thing before writing rather than trying to clear out he padding after write. freescale,vf610 - Use devm_ and dev_error_probe() to simplify code and allow dropping of explicit remove() callback. invensense,timestamp library - Use a cast to remove possibility of integer overflow. kionix,kx022a - Increase reset delay a little. maxim,max1363 - Use a buffer of sufficient size in iio_priv() rather than allocating variable sized buffer at use time. microchip,mcp4725 - Replace of_property_read_bool() with of_property_present() for detecting presence of regulator which is obviously not a bool. nxp,fxls8962af - Add wakeup-source property to the dt binding to allow these sensors to wake the system up from suspend. - Enable finer grained build when not all bus types need to be supported. renesas,rzg2l - Use dev_err_probe(), improving handling of probe errors and simplifying code. - Convert to devm_ based cleanup. - Remove unnecessary runtime PM complexity as clocks are managed through PM domains. - Switch pm_ptr() removing need for __maybe_unused markings. - use read_poll_timeout() to replace open coded equivalent. samsung, ssp_sensors - Simplify code by always providing timestamp whether or not it is enabled. st,lsm6dsx - Avoid need to include linux/i3c/master by using i3cdev_to_dev() to get to the contained struct device. st,stm32-timer-trigger - Check for clk_enable() fails. vishay,veml6030 - Use new gts-helper functions and fix the _scale attribute to take into account changes in gain and integration time.

2025-01-10misc: fastrpc: Fix copy buffer page sizeEkansh Gupta
For non-registered buffer, fastrpc driver copies the buffer and pass it to the remote subsystem. There is a problem with current implementation of page size calculation which is not considering the offset in the calculation. This might lead to passing of improper and out-of-bounds page size which could result in memory issue. Calculate page start and page end using the offset adjusted address instead of absolute address.

2025-01-10misc: fastrpc: Fix registered buffer page addressEkansh Gupta
For registered buffers, fastrpc driver sends the buffer information to remote subsystem. There is a problem with current implementation where the page address is being sent with an offset leading to improper buffer address on DSP. This is leads to functional failures as DSP expects base address in page information and extracts offset information from remote arguments. Mask the offset and pass the base page address to DSP. This issue is observed is a corner case when some buffer which is registered with fastrpc framework is passed with some offset by user and then the DSP implementation tried to read the data. As DSP expects base address and takes care of offsetting with remote arguments, passing an offsetted address will result in some unexpected data read in DSP. All generic usecases usually pass the buffer as it is hence is problem is not usually observed. If someone tries to pass offsetted buffer and then tries to compare data at HLOS and DSP end, then the ambiguity will be observed.

2025-01-10nvmem: core: improve range check for nvmem_cell_write()Jennifer Berringer
When __nvmem_cell_entry_write() is called for an nvmem cell that does not need bit shifting, it requires that the len parameter exactly matches the nvmem cell size. However, when the nvmem cell has a nonzero bit_offset, it was skipping this check. Accepting values of len larger than the cell size results in nvmem_cell_prepare_write_buffer() trying to write past the end of a heap buffer that it allocates. Add a check to avoid that problem and instead return -EINVAL when len doesn't match the number of bits expected by the nvmem cell when bit_offset is nonzero. This check uses cell->nbits in order to allow providing the smaller size to cells that are shifted into another byte by bit_offset. For example, a cell with nbits=8 and nonzero bit_offset would have bytes=2 but should accept a 1-byte write here, although no current callers depend on this.

2025-01-10nvmem: imx-ocotp-ele: set word length to 1Sascha Hauer
The ELE hardware internally has a word length of 4. However, among other things we store MAC addresses in the ELE OCOTP. With a length of 6 bytes these are naturally unaligned to the word length. Therefore we must support unaligned reads in reg_read() and indeed it works properly when reg_read() is called via nvmem_reg_read(). Setting the word size to 4 has the only visible effect that doing unaligned reads from userspace via bin_attr_nvmem_read() do not work because they are rejected by that function. Given that we have to abstract from word accesses to byte accesses in the driver, set the word size to 1. This allows bytewise accesses from userspace to be able to test what the driver has to support anyway.

2025-01-10nvmem: imx-ocotp-ele: fix MAC address byte orderSascha Hauer
According to the i.MX93 Fusemap the two MAC addresses are stored in words 315 to 317 like this: 315 MAC1_ADDR_31_0[31:0] 316 MAC1_ADDR_47_32[47:32] MAC2_ADDR_15_0[15:0] 317 MAC2_ADDR_47_16[31:0] This means the MAC addresses are stored in reverse byte order. We have to swap the bytes before passing them to the upper layers. The storage format is consistent to the one used on i.MX6 using imx-ocotp driver which does the same byte swapping as introduced here. With this patch the MAC address on my i.MX93 TQ board correctly reads as 00:d0:93:6b:27:b8 instead of b8:27:6b:93:d0:00.

2025-01-10nvmem: imx-ocotp-ele: fix reading from non zero offsetSascha Hauer
In imx_ocotp_reg_read() the offset comes in as bytes and not as words. This means we have to divide offset by 4 to get to the correct word offset. Also the incoming offset might not be word aligned. In order to read from the OCOTP the driver aligns down the previous word boundary and reads from there. This means we have to skip this alignment offset from the temporary buffer when copying the data to the output buffer.

2025-01-10virtio: console: Replace deprecated kmap_atomic with kmap_local_pageDavid Reaver
kmap_atomic() is deprecated and should be replaced with kmap_local_page() [1][2]. kmap_local_page() is faster in kernels with HIGHMEM enabled, can take page faults, and allows preemption. According to [2], this replacement is safe as long as the code between kmap_atomic() and kunmap_atomic() does not implicitly depend on disabling page faults or preemption. In this patch, the only thing happening between mapping and unmapping the page is a memcpy, and I don't suspect it depends on disabling page faults or preemption.

2025-01-10pps: clients: gpio: Bypass edge's direction check when not neededBastien Curutchet
In the IRQ handler, the GPIO's state is read to verify the direction of the edge that triggered the interruption before generating the PPS event. If a pulse is too short, the GPIO line can reach back its original state before this verification and the PPS event is lost. This check is needed when info->capture_clear is set because it needs interruptions on both rising and falling edges. When info->capture_clear is not set, interruption is triggered by one edge only so this check can be omitted. Add a warning if irq_handler is left without triggering any PPS event. Bypass the edge's direction verification when info->capture_clear is not set.

For every call to DSP, fastrpc driver passes the process tgid which works as an identifier for the DSP to enqueue the tasks to specific PD. With current design, if any process opens device node more than once and makes PD init request, same tgid will be passed to DSP which will be considered a bad request and this will result in failure as the same identifier cannot be used for multiple DSP PD. Assign and pass a client ID to DSP which would be assigned during device open and will be dependent on the index of session allocated for the PD. This will allow the same process to open the device more than once and spawn multiple dynamic PD for ease of processing.

Unloading the cp500 module leads to the following warning: kernfs: can not remove 'eeprom', no directory WARNING: CPU: 1 PID: 1610 at fs/kernfs/dir.c:1683 kernfs_remove_by_name_ns+0xb1/0xc0 The parent I2C device of the nvmem devices is freed before the nvmem devices. The reference to the nvmem devices is put by devm after cp500_remove(), but at this time the parent I2C device does not exist anymore as the I2C controller and its devices have already been freed in cp500_remove(). Thus, nvmem tries to remove an entry from an already deleted directory. Free nvmem devices before I2C controller auxiliary device.

2025-01-10misc: Kconfig: Make MCHP_LAN966X_PCI depend on OF_OVERLAYRicardo Ribalda
Drivers should depend on configurations that can be user-configurable instead of selecting them. Without this patch, OF cannot be disabled this way: make allyesconfig scripts/config -d OF make olddefconfig Which is a typical test in CI systems like media-ci. Now that we are at it, remove the dependency on OF, it will come automatically from OF_OVERLAY.

These template files for this tool have proper headers with the SPDX License information, which are included as Jinja comments by enclosing the text with '{#' and '#}'. Sofar, the spdxcheck script does not support to properly parse this license information in Jinja comments and it reports back with 'Invalid token: #}'.

2025-01-08ntsync: Introduce alertable waits.Elizabeth Figura
NT waits can optionally be made "alertable". This is a special channel for thread wakeup that is mildly similar to SIGIO. A thread has an internal single bit of "alerted" state, and if a thread is alerted while an alertable wait, the wait will return a special value, consume the "alerted" state, and will not consume any of its objects. Alerts are implemented using events; the user-space NT emulator is expected to create an internal ntsync event for each thread and pass that event to wait functions.
