ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Jonathan writes: IIO: New device support, features and cleanup for the 6.15 cycle. The usual mixture of new drivers, support in existing drivers for new devices, a range of features and general subsystem cleanup. Two merges of immutable branches in here: * SPI offload support. Culmination of a long effort to bring the ability to offload triggered sequences of SPI operations to specific hardware, allow high datarate acquisition over an SPI bus (if you have the right hardware / FPGA firmware) * GPIO set-array-helper - enables code simplification. New device support ================== adi,ad3552r-hs: - Add support for AD3541r and AD3542r via newly supported FPGA HDL. adi,ad4030 - New driver supporting the AD4030, AD4630 AD4630-16, AD4640-24, AD4632-16, AD4632-24 1 and 2 channel high precision SPI ADCs. adi,ad4851 - New driver and backend support for the AD4851, AD4852, AD4853, AD4854, AD4855, AD4846, AD4857, AD4858 and AD4858I high speed multichannel simultaneous sampling ADCs. adi,ad7191 - New driver for this 24-bit ADC for precision bridge applications, adi,ad7380 - Add support for the adaq4381-4 which is a 14-bit version of the already supported adaq4380-1 adi,adis16550 - New driver using the ADIS library (which needed extensions) for this IMU. brcm,apds9160 - New driver for this proximity and ambient light sensor. dynaimage,al3000a - New driver for this illuminance sensor. mcube,mc3230 - Add support for the mc3510c accelerometer with a different scale to existing supported parts (some rework preceded this) nxp,imx93 - Add compatibles for imx94 and imx95 which are fully compatible with imx93. rockchip,saradc - Add support for the RK3528 ADC - Add support for the RK3562 ADC silab,si7210 - New driver to support this I2C Hall effect magnetic position sensor. ti,ads7138 - New driver supporting the ADS7128 and AD7138 I2C ADCs. Staging driver drop =================== adi,adis16240 - Drop this impact sensor. Interesting part but complex hence never left staging due to ABI challenges. No longer readily available so drop driver. New features ============ Documentation - A really nice overview document introduce ADC terminology and how it maps to IIO. core - New description for FAULT events, used in the ad7173. - filter_type ABI used in ad4130. buffer-dmaengine - Split DMA channel request from buffer allocation (for SPI offload) - Add a new _with_handle setup variant. (for SPI offload) adi,adf4371 - Add control of reference clock type and support for frequency doubling where appropriate. adi,ad4695 - Support SPI offload. - Support oversampling control. adi,ad5791 - Support SPI offload. adi,ad7124 - Add channel calibration support. adi,ad7380: - Alert support (threshold interrupts) - SPI offload support. adi,ad7606 - Support writing registers when using backend enabling software control of modes. adi,ad7944 - Support SPI offload. adi,ad9832 - Use devm_regulator_get_enable() to simplify code. adi,ad9834 - Use devm_regulator_get_enable() to simplify code. adi,adxl345 - Improve IRQ handling code. - Add debug access to registers. bosch,bmi270 - Add temperature channel support. - Add data ready trigger. google,cross_ec - Add trace events. mcube,mc3230 - Add mount matrix support - Add an OF match table. Cleanup and minor bug fixes =========================== Tree wide: - Stop using iio_device_claim_direct_scoped() and introduce sparse friendly iio_device_claim/release_direct() The conditional scoped cleanup has proved hard to deal with, requiring workarounds for various compiler issues and in is rather non-intuitive so abandon that experiment. One of the attractions of that approach was that it made it much harder to have unbalanced claim/release bugs so instead introduce a conditional-lock style boolean returning new pair of functions. These are inline in the header and have __acquire and __release calls allowing sparse to detect lack of balance. There are occasional false positives but so far those have reflected complex code paths that benefited from cleanup anyway. The first set of driver conversions are in this pull request, more to follow next cycle. Various related cleanup in drivers. Removal of the _scoped code is completed and the definition removed. - Use of str_enable_disable() and similar helpers. - Don't set regmap cache to REGCACHE_NONE as that's the default anyway. - Change some caches from RBTREE to MAPLE reflecting best practice. - Use the new gpiod_multi_set_value_cansleep() - Make sure to grab direct mode for some calibrations paths. - Avoid using memcmp on structures when checking for matching channel configs. Instead just match field by field. dt-bindings: - Fix up indentation inconsistencies. gts-helper: - Simplify building of available scale table. adi,ad-sigma-delta - Make sure to disable channel after calibration done. - Add error handling in configuring channel during calibration. adi,ad2s1201 - use a bitmap_write() rather than directly accessing underlying storage. adi,ad3552r-hs - Fix a wrong error message. - Make sure to use instruction mode for configuration. adi,ad4695 - Add a conversion to ensure exit from conversion mode. - Use custom regmap to handle required sclk rate change. - Fix an out of bounds array access - Simplify oversampling ratio handling. adi,ad4851 - Fix a sign bug. adi,ad5791 - Fix wrong exported number of storage bits. adi,ad7124 - Disable all channels at probe to avoid strange initial configurations. adi,ad7173 - Rework to allow static const struct ad_sigma_delta without need to make a copy. adi,ad7623 - Drop a BSD license tag that the authors consider unnecessary. adi,ad7768-1 - Fix channels sign description exposed to user space. - Set MOSI idle state to avoid accidental device reset. - Avoid some overkill locking. adi,axi-dac - Check if device interface is busy when enabling data stream. - Add control of bus mode. bosch,bmi270 - Move a struct definition to a c file as only used there. vishay,veml6030 - Enable regmap cache to reduce bus traffic. - Fix ABI bug around scale reporting. vishay,vem6075 - Check array bounds to harden against broken hardware.

Merge series from Ryan Walklin <ryan@testtoast.com>: Hi All, V3 of this patch adding headphone jack detection support to the Anbernic RGnnXX series of handhelds. V3 corrects my misunderstanding of derivation of ALSA UCM file paths, and adds recieved Reviewed-by and Tested-by tags. Thanks to those that have reviewed and fed back on previous versions. Original message below: This series adds the required device tree bindings to describe GPIOs for jack detection in the sun4i-codec driver, adds support for jack detection to the codec machine driver, and describes the hardware configuration in the RG35XX DTS. The existing speaker amplifier GPIO pin can then be used in concert with jack detection to enable userspace sound servers (via an ALSA UCM configuration) to disable the speaker route when headphones are connected.

2025-03-14dt-bindings: connector: Add the GOcontroll Moduline module slot bindingsMaud Spierings1-0/+88
Add the bindings that describe a GOcontroll Moduline module slot. This slot provides all the interfaces to interface with a Moduline compatible IO module. The actual module is not reasonable to describe as it can be swapped at will, with this connector the driver will be able to probe for a module on boot. The connector consists of 2 parts, one part for interfacing with the SoC and main board, the other part has 13 IO channels for the module to interact with the outside world. The functions of these IO channels are determined by the type of module in the slot. The IO on the SoC side is as follows: - a 3v3 supply, this tends to be the logic level of the module and its microcontroller - a 5v0 supply, this can be used to power low power peripherals on the module - a 6v-8v supply, this can be used for high power peripherals on the module - a 6v-30v supply, this tends to be a dirty supply that comes from the controller supply after some circuit protection, or is the same as the 6v-8v supply. - an SPI bus which carries the communication between the SoC and the microcontroller on the module. - an I2C bus shared between the SoC and all module slots which can carry direct module-to-module communication. - a reset line - an interrupt line that indicates a clear to transmit signal - a sync line shared between the SoC and all module slots which could be used to synchronize modules for time sensitive IO spread across modules. - a SMBus alert line that is shared between the modules but is not connected to the SoC so that is ignored. A slot-number property is used to identify the physical location of a module slot. Without it, it would be impossible to identify which module to control if there are multiple of one type, to address the desired IO.

For several zoned storage devices, vendors will provide extra space which was used for device level GC than specs and F2FS can use this space for filesystem level GC. To do that, we can reserve the space using reserved_blocks. However, it is not enough, since this extra space should not be shown to users. So, with this new sysfs node, we can hide the space by substracting reserved_blocks from total bytes.

2025-03-13dt-bindings: dsp: fsl,dsp: Add resets propertyDaniel Baluta1-1/+23
Assert and deassert functionality of the DSP found on i.MX8MP is realized by combining control bits from two modules: Audio Block Control and Debug Access Port. Audio block control bits are used to Run/Stall the DSP core while the DAP bits are used for software reset the core. The original plan was to use fsl,dsp-ctrl property and to refer the audiomix bits via syscon interface. This proposal received NACK from community we shouldn't abuse the syscon interface [1]. So remove fsl,dsp-ctrl property for i.MX8MP and use reset control interface instead. Example dts node only uses runstall control now, but softreset will be added in the future when we will convert the softreset functionality to use reset controller API.

2025-03-13dt-bindings: pinctrl: add compatible for Allwinner A523/T527Andre Przywara1-0/+175
The A523 contains a pin controller similar to previous SoCs, although using 10 GPIO banks (PortB-PortK), all of them being IRQ capable. With this SoC we introduce a new style of binding, where the pinmux values for each pin group are stored in the new "allwinner,pinmux" property in the DT node, instead of requiring every driver to store a mapping between the function names and the required pinmux. Add a new binding file, since all the different variants of the old binding are making the file a bit unwieldy to handle already, and the new property would make the situation worse.

2025-03-13dt-bindings: net: rockchip-dwmac: Require rockchip,grf and rockchip,php-grfJonas Karlman1-3/+18
All Rockchip GMAC variants typically write to GRF regs to control e.g. interface mode, speed and MAC rx/tx delay. Newer SoCs such as RK3562, RK3576 and RK3588 use a mix of GRF and peripheral GRF regs. Prior to the commit b331b8ef86f0 ("dt-bindings: net: convert rockchip-dwmac to json-schema") the property rockchip,grf was listed under "Required properties". During the conversion this was lost and rockchip,grf has since then incorrectly been treated as optional and not as required. Similarly, when rockchip,php-grf was added to the schema in the commit a2b77831427c ("dt-bindings: net: rockchip-dwmac: add rk3588 gmac compatible") it also incorrectly has been treated as optional for all GMAC variants, when it should have been required for RK3588, and later also for RK3576. Update this binding to require rockchip,grf and rockchip,php-grf to properly reflect that GRF (and peripheral GRF for RK3576/RK3588) is required to control part of GMAC. This should not introduce any breakage as all Rockchip GMAC nodes have been added together with a rockchip,grf phandle (and rockchip,php-grf where required) in their initial commit.
