of: remove internal arguments from of_property_for_each_u32()

2024-07-25T11:53:47Z

The of_property_for_each_u32() macro needs five parameters, two of which are primarily meant as internal variables for the macro itself (in the for() clause). Yet these two parameters are used by a few drivers, and this can be considered misuse or at least bad practice. Now that the kernel uses C11 to build, these two parameters can be avoided by declaring them internally, thus changing this pattern: struct property *prop; const __be32 *p; u32 val; of_property_for_each_u32(np, "xyz", prop, p, val) { ... } to this: u32 val; of_property_for_each_u32(np, "xyz", val) { ... } However two variables cannot be declared in the for clause even with C11, so declare one struct that contain the two variables we actually need. As the variables inside this struct are not meant to be used by users of this macro, give the struct instance the noticeable name "_it" so it is visible during code reviews, helping to avoid new code to use it directly. Most usages are trivially converted as they do not use those two parameters, as expected. The non-trivial cases are: - drivers/clk/clk.c, of_clk_get_parent_name(): easily doable anyway - drivers/clk/clk-si5351.c, si5351_dt_parse(): this is more complex as the checks had to be replicated in a different way, making code more verbose and somewhat uglier, but I refrained from a full rework to keep as much of the original code untouched having no hardware to test my changes All the changes have been build tested. The few for which I have the hardware have been runtime-tested too.

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 ...

Add a driver to support reading the Auxiliary ADC IP found in the MediaTek MT6357, MT6358 and MT6359 Power Management ICs, featuring a different register layout, configuration reset and ADC reading sequence from the other already supported MediaTek SoC or PMIC (aux)ADC HW. This driver provides multiple ADC channels for system monitoring, such as battery voltage, PMIC temperature, PMIC-internal voltage regulators temperature, and others.

iio: xilinx-ams: Add labels

2024-06-30T10:41:19Z

Label all the channels using names from the reference manual. Some of the "control" channels are duplicates of other channels. The reference manual describes it like: > The AMS register set includes several measurement registers that are > written to by the PS SYSMON unit using the single-channel mode > (sequencer off). These voltage measurements are performed using the > unipolar sampling circuit with a 0 to 3V range and do not have alarms > or minimum/maximum registers. So I think these really are measuring the same voltages but in a different location. In which case, sharing labels makes sense to me.
