(2024-04-21 18:42:33 +0100) ---------------------------------------------------------------- IIO: 1st set of new device support, features and cleanup for 6.10 The Analog Device team (Paul Cercueil and Nuno Sa) have been working on improving high speed device handling. They have had some support in their own tree for many years, so it is great to see them bring it to upstream. Some of that is seen here, with the first output device using the IIO dmaengine infrastructure and a new DAC backend FPGA IP driver. This makes use of a new set of interfaces to allow backend and front end driver communication in a fashion that in theory at least allows for a single driver for a given ADC / DAC independent of the IP to which is being used to deal with the data bus and DMA aspects of working with these devices. It is early days for this new generic way of handling split devices, but as it's kernel internals only we can merrily change anything about it as a wider diversity of devices show up and we get a better feel for what works. Alongside the usual set of new drivers and features we have the automatic cleanup of fwnode_handle_put() which didn't quite make it in last cycle. The equivalent DT version was merged by Rob Herring via the DT binding tree and one patch using that in IIO can also be found in this pull request. Rob has been making extensive use of that infrastructure in the DT core which is good to see and provides more evidence this basic approach is useful. In some cases, the IIO driver was converted over from DT only to using the generic firmware description handling of property.h including using the new macros. The general preference for IIO is to use this more generic handling where possible - a bunch of other drivers have been converted this cycle as well. New device support ================== adi,ad7173 - New driver supporting AD7172-2, AD7172-4 AD7173-9, AD7175-2, AD7175-8, AD7176-2 and AD7177-2 ADCs. - Follow up fix for an accidental use of logic not instead of bitwise. adi,ad7944 - New driver supporting AD7944, AD7985 and AD7986 pin compatible ADCs. - Later patch added use of new spi_optimize_message() to reduce overheads of setting up a reused message. - Additional changes later in series reduced code duplication. adi,ad9739a RF DAC - New driver for this 14-bit 2.5 GSPS DAC via an LVDS interface. adi,axi-dac - Support for this FPGA IP used to send data to high performance DACs over an interface such as JESD204B/C or parallel interfaces. Used in conjunction with a DAC driver. The initial user is the ad9739a. The dmaengine-buffer needed various changes to make it bidirectional. avago,apds9306 - New driver for this ambient light sensor. - Fix much later in this pull for an off by 1 error. New device IDs ============== For these at most an ID and a instance of chip specific data was needed. Always nice to see manufacturers sticking to an existing software interface for new parts. allwinner,sun20i - Add support for h616. invensense,mpu6050 - Add support for ICM42688 maxim,max30102 - Add compatible for MAX30101 ti,dac5571 - Add compatible for DAC081C081 General ======= fwnode_handle - Support for cleanup.h based __free(fwnode_handle) - Loop macro using this for looping over child nodes without needing to call fwnode_handle_put() in ever early exit from the loop. - Used in: * adi,ad3552r * adi,ad4130 * adi,ad5770r * adi,ad74413r * adi,ad7173 * adi,adfm2000 * linear,ltc2688 * linear,ltc2983 * maxim,max11410 * microchip,pac1934 * qcom,spmi-adc * renesas,rz2gl * st,ab8500 * st,stm32 (Fix for failure to set return value precedes this patch, providing an example of why enabling direct returns makes bugs less likely) - Conversions to fwnode also using the cleanup logic * adi,ad7124 * adi,ad7292 * freescale,fsl-imx25-gcq - Other conversions to fwnode where the new cleanup handling isn't useful * adi,ad7192 * avia,hx711 * freescale,mma8452 * nxp,fxls8962af * st,spear * ti,twl4030 Features ======== adi,adxl345 - Support SPI_3WIRE mode. adi,ad9944 - Support 3-wire mode, note this isn't normal 3-wire SPI (unlike the adxl345 change above), but rather a wiring scheme where the SPI chip select is used to trigger conversions rather than using a separate pin. - Add some device specific documentation, mostly around the various wiring schemes. invensense,mpu6050 - Add Wake on Motion support as an IIO event and as a wake-up source. linear,ltc2983 - Add vdd-supply. ti,hdc3020 - Add power management using trigger on demand mode and adding suspend and resume handling. - Use reset GPIO if available. Cleanup and fixes ================ iio core - Use the various autocleanup and lock guards from cleanup.h to simplify the IIO core. - Don't set the pointer used for iio_priv() if it is zero sized as that points beyond the end of the allocation. No driver actually uses it in that case but good to clean this up. various drivers - Drop unnecessary casts of other pointer types to void * docs - Add missing ABI entry for in_temp_input. adi,adx345 - General cleanup prior to adding spi-3wire mode. adi,axi-adc - Be more flexible and allow minor version changes as these are expected to be backwards compatible. avago,apds9300/9600 - Merge near identical bindings. The drivers are quite different, but the bindings can be shared. The apds9306 binding introduced in this series uses this shared binding doc as well. - Add missing vdd-supply - Update binding to use IRQ_TYPE_LEVEL_LOW instead of 8. bosch,bmp280 - Organize headers freescale,fxl-imx25-gcq - Use devm_ for remaining probe() time setup allowing dropping of specific error handling and remove() functions. infineon,dps310 - Fix handling of negative temperatures - Bring style of other similar calls inline with the form needed for temperatures - Ensure error handling of regmap calls is consistent within the driver. - Simplify scale reading logic. invensense,mpu6050 - Flip logic in binding to exclude devices without i2c-gate instead of opting in. The list is expected to be much shorter as all recent devices support this feature. honeywell,hsc030pa - Use spi_read() instead of opening coding. renesas,rcar - Use device_for_each_child_of_node_scoped() to remove need to manually release. Left over from series the rest of which went in during 6.9. st,ab8500 - Fix naming of function parameters in kernel-doc ---------------------------------------------------------------- Andy Shevchenko (4): iio: adc: spear_adc: Make use of device properties iio: core: Leave private pointer NULL when no private data supplied iio: core: Calculate alloc_size only once in iio_device_alloc() iio: adc: twl4030-madc: Make use of device properties Chris Morgan (1): dt-bindings: iio: adc: Add GPADC for Allwinner H616 Christophe JAILLET (1): iio: pressure: hsc030pa: Use spi_read() Colin Ian King (1): iio: accel: adxl367: Remove second semicolon Dan Carpenter (2): iio: light: apds9306: Fix off by one in apds9306_sampling_freq_get() iio: adc: ad7173: Fix ! vs ~ typo in ad7173_sel_clk() David Lechner (8): dt-bindings: iio: adc: add ad7944 ADCs iio: adc: ad7944: add driver for AD7944/AD7985/AD7986 iio: adc: ad7944: Add support for "3-wire mode" MAINTAINERS: add Documentation/iio/ to IIO subsystem docs: iio: new docs for ad7944 driver iio: adc: ad7944: simplify adi,spi-mode property parsing iio: adc: ad7944: use spi_optimize_message() iio: adc: ad7944: Consolidate spi_sync() wrapper Dumitru Ceclan (6): dt-bindings: adc: add AD7173 iio: adc: ad_sigma_delta: Add optional irq selection iio: adc: ad7173: add AD7173 driver dt-bindings: adc: ad7173: add support for additional models iio: adc: ad7173: improve chip id's defines iio: adc: ad7173: add support for additional models Javier Carrasco (8): io: light: st_uvis25: drop casting to void in dev_set_drvdata iio: humidity: hts211: drop casting to void in dev_set_drvdata iio: imu: st_lsm6dsx: drop casting to void in dev_set_drvdata iio: humidity: hdc3020: add power management dt-bindings: iio: humidity: hdc3020: add reset-gpios iio: humidity: hdc3020: add reset management dt-bindings: iio: health: maxim,max30102: add max30101 iio: health: max30102: add support for max30101 Jean-Baptiste Maneyrol (6): iio: imu: inv_mpu6050: add WoM (Wake-on-Motion) sensor iio: imu: inv_mpu6050: add WoM event as accel event iio: imu: inv_mpu6050: add new interrupt handler for WoM events iio: imu: inv_mpu6050: add WoM suspend wakeup with low-power mode dt-bindings: iio: imu: add icm42688 inside inv_icm42600 iio: imu: inv_icm42600: add support of ICM-42688-P Jonathan Cameron (29): device property: Move fwnode_handle_put() into property.h device property: Add cleanup.h based fwnode_handle_put() scope based cleanup. device property: Introduce device_for_each_child_node_scoped() iio: adc: max11410: Use device_for_each_child_node_scoped() iio: addac: ad74413r: Use device_for_each_child_node_scoped() iio: dac: ltc2688: Use device_for_each_child_node_scoped() iio: adc: fsl-imx25-gcq: Switch from of specific handing to fwnode based. iio: adc: fsl-imx25-gcq: Use devm_* and dev_err_probe() to simplify probe iio: adc: ad7124: Switch from of specific to fwnode based property handling iio: adc: ad7292: Switch from of specific to fwnode property handling iio: adc: ad7192: Convert from of specific to fwnode property handling iio: accel: mma8452: Switch from of specific to fwnode property handling. iio: accel: fxls8962af: Switch from of specific to fwnode based properties. iio: adc: hx711: Switch from of specific to fwnode property handling. iio: temp: ltc2983: Use __free(fwnode_handle) and device_for_each_node_scoped() iio: adc: rzg2l_adc: Use device_for_each_child_node_scoped() iio: adc: rcar-gyroadc: use for_each_available_child_node_scoped() iio: dac: ad3552r: Use device_for_each_child_node_scoped() iio: dac: ad5770r: Use device_for_each_child_node_scoped() iio: adc: ab8500-gpadc: Fix kernel-doc parameter names. iio: adc: ab8500-gpadc: Use device_for_each_child_node_scoped() to simplify erorr paths. iio: adc: ad4130: Use device_for_each_child_node_scoped() to simplify error paths. iio: adc: ad7173: Use device_for_each_child_node_scoped() to simplify error paths. iio: frequency: admfm2000: Use device_for_each_child_node_scoped() to simplify error paths. iio: dac: ad3552: Use __free(fwnode_handle) to simplify error handling. iio: adc: pac1934: Use device_for_each_available_child_node_scoped() to simplify error handling. iio: adc: stm32: Fixing err code to not indicate success iio: adc: stm32: Use device_for_each_child_node_scoped() iio: adc: qcom-spmi-adc5: Use device_for_each_child_node_scoped() Krzysztof Kozlowski (1): iio: dac: ad5755: make use of of_device_id table Laurent Pinchart (2): dt-bindings: iio: dac: ti,dac5571: Add DAC081C081 support iio: dac: ti-dac5571: Add DAC081C081 support Lorenzo Bertin Salvador (1): iio: adc: ti-ads131e08: Use device_for_each_child_node_scoped() to simplify error paths.
