move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23Z

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

iio: adc: standardize on formatting for id match tables

2024-09-05T18:27:13Z

This is a frequent minor comment in reviews, so start cleaning up existing drivers in the hope we get fewer cases of cut and paste. There are not kernel wide rules for these, but for IIO the style that I prefer (and hence most common) is: - Space after { and before } - No comma after terminator { } This may cause merge conflicts but they should be trivial to resolve hence I have not broken this into per driver patches.

iio: adc: max11100: Fix alignment for DMA safety

2022-06-14T10:53:13Z

____cacheline_aligned is an insufficient guarantee for non-coherent DMA on platforms with 128 byte cachelines above L1. Switch to the updated IIO_DMA_MINALIGN definition. Update the comment to include 'may'.

iio: adc: max11100: Use devm_ functions for rest of probe()

2021-06-03T17:24:14Z

By using devm_add_action_or_reset() to manage the regulator disable, it becomes simple to use managed functions for all of remove. This simplifies error handling and allows us to drop the remove() function entirely.

iio:adc:max11100: Drop of_match_ptr protection / add mod_devicetable.h include

2020-07-07T19:24:09Z

Allows use of driver with ACPI PRP0001 base binding. Mostly this is about trying to avoid cut and paste of this into new drivers (it is a frequent review comment) rather than any thought that this driver might get used on an ACPI platform. The mod_devicetable.h include is to encourage best practice of including any header directly used within the code (here for of_match_id) Signed-off-by: Jonathan Cameron Acked-by: Jacopo Mondi Reviewed-by: Andy Shevchenko

iio: Remove superfluous of_node assignments

2020-06-14T13:20:08Z

If a driver does not assign an of_node to a IIO device to IIO core will automatically assign the of_node of the parent device. This automatic assignment is done in the iio_device_register() function. There is a fair amount of drivers that currently manually assign the of_node of the IIO device. All but 4 of them can make use of the automatic assignment though. The exceptions are: * mxs-lradc-adc: Which uses the of_node of the parent of the parent. * stm32-dfsdm-adc, stm32-adc and stm32-dac: Which reference the of_node assigned to the IIO device before iio_device_register() is called. All other drivers are updated to use automatic assignment. This reduces the amount of boilerplate code involved in setting up the IIO device. The patch has mostly been auto-generated with the following semantic patch // @exists@ expression indio_dev; expression parent; @@ indio_dev = $devm_iio_device_alloc\|iio_device_alloc$(&parent, ...) ... -indio_dev->dev.of_node = parent.of_node; @exists@ expression indio_dev; expression parent; @@ indio_dev = $devm_iio_device_alloc\|iio_device_alloc$(parent, ...) ... -indio_dev->dev.of_node = parent->of_node; // Signed-off-by: Lars-Peter Clausen Reviewed-by: Andy Shevchenko Signed-off-by: Jonathan Cameron

iio: remove explicit IIO device parent assignment

2020-06-14T10:49:59Z

This patch applies the semantic patch: @@ expression I, P, SP; @@ I = devm_iio_device_alloc(P, SP); ... - I->dev.parent = P; It updates 302 files and does 307 deletions. This semantic patch also removes some comments like '/* Establish that the iio_dev is a child of the i2c device */' But this is is only done in case where the block is left empty. The patch does not seem to cover all cases. It looks like in some cases a different variable is used in some cases to assign the parent, but it points to the same reference. In other cases, the block covered by ... may be just too big to be covered by the semantic patch. However, this looks pretty good as well, as it does cover a big bulk of the drivers that should remove the parent assignment. Signed-off-by: Alexandru Ardelean Signed-off-by: Jonathan Cameron
