12 daysmodule: Convert symbol namespace to string literalPeter Zijlstra1-1/+1
Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

2022-04-10iio: core: Simplify the registration of kfifo buffersMiquel Raynal1-1/+0
Among all the users of the kfifo buffers, no one uses the INDIO_BUFFER_HARDWARE mode. So let's take this as a general rule and simplify a little bit the internals - overall the documentation - by eliminating unused specific cases. Use the INDIO_BUFFER_SOFTWARE mode by default with kfifo buffers, which will basically mimic what all the "non direct" modes do.

2022-02-18iio:common:ssp_sensors: Move exports into IIO_SSP_SENSORS namespaceJonathan Cameron1-0/+1
In order to avoid unnecessary pollution of the global symbol namespace move the common/library functions into a specific namespace and import that into the various specific device drivers that use them. For more information see https://lwn.net/Articles/760045/ Both the exports used between the two common modules and the individual drivers are moved to a single namespace as greater granularity does not feel useful.

2021-03-11iio: make use of devm_iio_kfifo_buffer_setup() helperAlexandru Ardelean1-9/+5
All drivers that already call devm_iio_kfifo_allocate() & iio_device_attach_buffer() are simple to convert to iio_device_attach_kfifo_buffer() in a single go. This change does that; the unwind order is preserved. What is important, is that the devm_iio_kfifo_buffer_setup() be called after the indio_dev->modes is assigned, to make sure that INDIO_BUFFER_SOFTWARE flag is set and not overridden by the assignment to indio_dev->modes. Also, the INDIO_BUFFER_SOFTWARE has been removed from the assignments of 'indio_dev->modes' because it is set by devm_iio_kfifo_buffer_setup().

2020-06-14iio: Remove superfluous of_node assignmentsLars-Peter Clausen1-1/+0
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 // <smpl> @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; // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2020-06-14iio: remove explicit IIO device parent assignmentAlexandru Ardelean1-1/+0
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.
