2024-10-02move asm/unaligned.h to linux/unaligned.hAl Viro
asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

2024-07-04Merge tag 'iio-for-6.11b' of ↵Greg Kroah-Hartman
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 6.11 The big one here is we finally have Paul Cercueil's (and others) DMA buffer support for IIO devices enabling high speed zero copy transfer of data to and from sensors supported by IIO (and for example USB). This should aid with upstream support of a range of higher performance ADCs and DACs. Two merges from other trees - spi/spi_devm_optimize used for simplification in ad7944. - dmaengine/topic_dma_vec to enable the DMABUF series. One feature with impact outside IIO. - Richer set of dev_err_probe() like helpers to cover ERR_PTR() cases. New device support ================== adi,ad7173 - Add support for AD4111, AD4112, AD4114, AD4115 and ADC4116 pseudo differential ADCs. Major driver rework was needed to enabled these. adi,ad7944 - Use devm_spi_optimize_message() to avoid a local devm cleanup callback. This is the example case from the patch set, others will follow. mediatek,mt6359-auxadc - New driver for this ADC IP found in MT6357, MT6358 and MT6359 PMICs. st,accel - Add support for the LIS2DS12 accelerometer ti,ads1119 - New driver for this 16 bit 2-differential or 4-single ended channel ADC. Features ======== dt-bindings - Introduce new common-mode-channel property to help handle pseudo differential ADCs where we have something that looks like one side of differential input, but which is only suited for use with a slow moving reference. adi,adf4350 - Support use as a clock provider. iio-hmwon - Support reading of labels from IIO devices by their consumers and use this in the hwmon bridge. Cleanup and minor fixes ======================= Treewide - Use regmap_clear_bits() / regmap_set_bits() to simplify open coded equivalents. - Use devm_regulator_get_enable_read_voltage() to replace equivalent opencoded boilerplate. In some cases enabled complete conversion to devm handling and removal of explicit remove() callbacks. - Introduce dev_err_ptr_probe() and other variants and make use of of them in a couple of examples driver cleanups. Will find use in many more drivers soon. adi,ad7192 - Introduce local struct device *dev and use dev_err_probe() to give more readable code. adi,adi-axi-adc/dac - Improved consistency of messages using dev_err_probe() adi,adis - Split the trigger handling into cases that needed paging and those that don't resulting in more readable code. - Use cleanup.h to simplify error paths via scoped cleanup. - Add adis specific lock helpers and make use of them in a number of drivers. adi,ad7192 - Update maintainer (Alisa-Dariana Roman) adi,ad7606 - dt-binding cleanup. avago,apds9306 - Add a maintainer entry (Subhajit Ghosh) linear,ltc2309 - Fix a wrong endian type. st,stm32-dfsdm - Fix a missing port property in the dt-binding. st,sensors - Relax whoami match failure to a warning print rather than probe failure. This enables fallback compatibles to existing parts from those that don't necessarily even exit yet. * tag 'iio-for-6.11b' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (112 commits) iio: adc: ad7173: Fix uninitialized symbol is_current_chan iio: adc: Add support for MediaTek MT6357/8/9 Auxiliary ADC math.h: Add unsigned 8 bits fractional numbers type dt-bindings: iio: adc: Add MediaTek MT6359 PMIC AUXADC iio: common: scmi_iio: convert to dev_err_probe() iio: backend: make use of dev_err_cast_probe() iio: temperature: ltc2983: convert to dev_err_probe() dev_printk: add new dev_err_probe() helpers iio: xilinx-ams: Add labels iio: adc: ad7944: use devm_spi_optimize_message() Documentation: iio: Document high-speed DMABUF based API iio: buffer-dmaengine: Support new DMABUF based userspace API iio: buffer-dma: Enable support for DMABUFs iio: core: Add new DMABUF interface infrastructure MAINTAINERS: Update AD7192 driver maintainer iio: adc: ad7192: use devm_regulator_get_enable_read_voltage iio: st_sensors: relax WhoAmI check in st_sensors_verify_id() MAINTAINERS: Add AVAGO APDS9306 dt-bindings: iio: adc: adi,ad7606: comment and sort the compatible names dt-bindings: iio: adc: adi,ad7606: add missing datasheet link ...

Provide a way for bus specific pre-configuration by adding a function pointer argument to the driver core's probe() function, and keep the driver core implementation bus independent. In case NULL was passed, a regmap_write() shall initialize all bits of the data_format register, else regmap_update() is used. In this way spi and i2c are covered.

2024-03-28iio: accel: mxc4005: Reset chip on probe() and resume()Hans de Goede
On some designs the chip is not properly reset when powered up at boot or after a suspend/resume cycle. Use the sw-reset feature to ensure that the chip is in a clean state after probe() / resume() and in the case of resume() restore the settings (scale, trigger-enabled).

2024-03-28iio: accel: mxc4005: Interrupt handling fixesHans de Goede
There are 2 issues with interrupt handling in the mxc4005 driver: 1. mxc4005_set_trigger_state() writes MXC4005_REG_INT_MASK1_BIT_DRDYE (0x01) to INT_MASK1 to enable the interrupt, but to disable the interrupt it writes ~MXC4005_REG_INT_MASK1_BIT_DRDYE which is 0xfe, so it enables all other interrupt sources in the INT_SRC1 register. On the MXC4005 this is not an issue because only bit 0 of the register is used. On the MXC6655 OTOH this is a problem since bit7 is used as TC (Temperature Compensation) disable bit and writing 1 to this disables Temperature Compensation which should only be done when running self-tests on the chip. Write 0 instead of ~MXC4005_REG_INT_MASK1_BIT_DRDYE to disable the interrupts to fix this. 2. The datasheets for the MXC4005 / MXC6655 do not state what the reset value for the INT_MASK0 and INT_MASK1 registers is and since these are write only we also cannot learn this from the hw. Presumably the reset value for both is all 0, which means all interrupts disabled. Explicitly set both registers to 0 from mxc4005_chip_init() to ensure both masks are actually set to 0.

In this case only use was to get an irq so easily converted. Also include linux/mod_devicetable.h for struct of_device_id definition. Using the generic firmware handling, this driver may be used with other firmware types. This also removes an example that might get copied into other drivers leaving them unable to be used with alternative firmware types.
