2024-11-11fpga: Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/fpga to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. A few white space changes are included to make indention consistent.

2024-11-10mei: vsc: Do not re-enable interrupt from vsc_tp_reset()Hans de Goede
The only 2 callers of vsc_tp_reset() are: 1. mei_vsc_hw_reset(), which immediataly calls vsc_tp_intr_disable() afterwards. 2. vsc_tp_shutdown() which immediately calls free_irq() afterwards. So neither actually wants the interrupt to be enabled after resetting the chip and having the interrupt enabled for a short time afer the reset is undesirable. Drop the enable_irq() call from vsc_tp_reset(), so that the interrupt is left disabled after vsc_tp_reset().

2024-11-10spmi: pmic-arb: fix return path in for_each_available_child_of_node()Javier Carrasco
This loop requires explicit calls to of_node_put() upon early exits (break, goto, return) to decrement the child refcounter and avoid memory leaks if the child is not required out of the loop. A more robust solution is using the scoped variant of the macro, which automatically calls of_node_put() when the child goes out of scope.

ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Jonathan writes: IIO: 2nd set of new device support, features and cleanup for 6.13 Alongside new drivers and device support there are several large cleanups going on across the IIO tree and we see part of some of those in this pull request. Merged char-misc-next at point of 6.12-rc6 merge to avoid a conflict with a fix for the ad7380 merged earlier this cycle. Note that I previously messed this merge up and had to reconstruct it this morning so a coherent pull request was possible. The new stuff is all the same as has been in linux-next for some time with the exception of the kernel-doc related __private ordering fix that went in yesterday. New device support ================== adi,ad7380 - Support for adaq4370-4 and adaq4370 quad channel ADCs. adi,ad7606 - Various cleanups preceeding support of AD7607, AD7608 and AD7609 ADCs. adi,ad7779 - New driver supproting AD7770, AD7771 and AD7779 ADCs. allegro,als31300 - New driver for this 3D Linear Hall Effect sensor. bosch,bmi270 - Add support BMI260 which is similar but requires a different firmware image. bosch,smi240 - New driver for this IMU. ti,opt3001 - Add support opt3002 light sensor which has a wider spectral range than the opt3001. vishay,veml3235 - New driver for this ambient light sensor. Features ======== hid-sensors - Add support Human Proximity Range and Attention detection (requiring a new classification style channel type) adi,ad3552r - Add backend support and related platform driver to support use with an FPGA IP to allow QSPI + DDR bus operation and much higher data aquisition rates. (various rework preceeded this feature) adi,ad7606 - Various cleanup prior to enabling use with an IIO Backend and PWM trigger enabling much higher speed data capture. bosch,bme680 - Support control of preheat current - Support triggered buffer capture - Add SCALE and RAW channels (needed to enable the buffered capture). bosch,bmp280 - Enable sleeping to save power. - Add interrupt support for bmp3xx and bmp5xx devices. Also update bmp085 to new approach. - Enable data ready trigger. bosch,bmi270 - Add triggered buffer support - Add scale and sampling frequency control. vishay,veml6070 - Support integration time via DT binding for an external resistor value. Cleanup and minor fixes ======================= core - Fix a longstanding issue with event codes for differential channels. Note that not all drivers are yet fixed, but macros have been added to avoid potential repeats of this in future. - Tidy up handling in iio_read_acpi_mount matrix. - Mark iio_dev::priv with __private. Later move the marking before the field name to avoid a kernel-doc issue. treewide - Drop some pointless default n entries in Kconfig. - Add an iio_get_acpi_device_name_and_data() handler to replace some commonly repeated code. - simplify use of 'state' in write_event_config() callback as it is effectively a boolean. Once done make it a boolean (lots of drivers were updated to enable this) - some more use of devm_regulator_get_enable_read_voltage( to replace open coded versions. Where this enables it convert all of remove handling to devm based and drop the remove callback. - check returns from devm_mutex_init() accel drivers - Use aligned_s64 instead of s64 __aligned(8) adi,ad5791 - Add some missing GPIOs and power supplies that presumably were always hard wired on previous boards. - Refactor to use chip_info in device id tables. - Convert probe entirely to devm based simplify code and allowing remove() callback to be dropped. adi,ad7192 - Check return from spi_get_device_match_data() adi,ad74413r - Don't keep an unnecessary copy of the gpio after probe. - Use devm_regulator_get_enable_read_voltage() instead of open coding. - Apply cleanup.h approach to reduce complexity. adi,dac8460 - Fix a wrong compaitble ID due to a stray space. - Add an spi_device_id table. bosch,bmc150 - Drop some likely false ACPI IDs. - Drop left over unused ACPI specific code. bosch,bme680 - Add mising regmap.h include. - Reduce excessive sleep on startup. - Drop some cammelcase usage. - Use fsleep - Generalize read functions to allow for reuse. - Use s16 variable to avoid some incorrect casting bosch,bmg150 - Drop some likely false ACPI IDs. bosch,bmi270 - Drop unused FREQUENCY and SCALE attributes that always returned an error (they wil be back impelmented correctly). - Factor out the chip specific data into a structure to enable simple support for additional devices. isil,isl29018 - Drop ACPI_PTR() and CONFIG_ACPI guards as not worth the trouble for very minor saving. invensense,mpu6050 - Use much simpler test for ACPI firmware. kionix,kxcjk-1013 - Drop unnecessary ACPI entry in the i2c_device_id table. - Drop support KX022-1020 to fix a bug that was introduced with that change. Hopefully a fixed version will replace it soon. - Drop CONFIG guards for PM in favor of pm_ptr() and the compiler removing dead code. - Switch from enum to chip_info structure and add ODR times to that structure. - Deduplicate one of those ODR structures - Drop ACPI_PTR() and move ID table out of config guards. - Minor additional cleanup. liteon,ltr401 - Drop some likely false ACPI Ids and add LTER0303 which is know to be in use. microchip,pac1934 - Use much simpler test for ACPI firmware. vishay,veml6070 - Use unsigned int instead of just unsigned. - Use FIELD_PREP to make setting of field value explicit.

2024-11-09iio: adc: ad7380: fix oversampling formulaJulien Stephan
The formula in the datasheet for oversampling time conversion seems to be valid when device is at full speed using the maximum number of SDO lines. The driver currently support only 1 SDO line. The correct formula is: t_convert = T_CONVERT_0_NS + T_CONVERT_X_NS*(x - 1)*num_channel/number_of_sdo_lines. It will produce larger delays than what is currently set, but some devices actually require it.

Convert all platform drivers matched by the "CHAR and MISC DRIVERS" maintainer's entry to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

2024-11-05nvmem: Add R-Car E-FUSE driverGeert Uytterhoeven
R-Car Gen4 SoCs contain fuses indicating hardware support or hardware (e.g. tuning) parameters. Add a driver to access the state of the fuses. This supports two types of hardware fuse providers: 1. E-FUSE non-volatile memory accessible through the Pin Function Controller on R-Car V3U and S4-8, 2. E-FUSE non-volatile memory accessible through OTP_MEM on R-Car V4H and V4M. The state of the cells can be read using the NVMEM framework, either from kernel space (e.g. by the Renesas UFSHCD driver), or from userspace.

Add triggered buffer and soft timestamp support. The available scan mask enables all the channels of the sensor in order to follow the operation of the sensor. The sensor basically starts to capture from all channels as long as it enters into FORCED mode. The bulk read, reads a total of 15 registers from the sensor, 0x1D..0x2B. Even though some of those registers are not reported in the register map of the device, this is how the BME680 Sensor API [1] proposes to do it. This allows to have one bulk read instead of multiple ones.
