| | | | | | | | | | | | ACPI_PTR() is more harmful than helpful. For example, in this case if CONFIG_ACPI=n, the ID table left unused and code is obfuscated by ifdeffery. Drop anti-pattern of ACPI_PTR() use.

* iio: adc: ti-adc128s052: Switch to use spi_get_device_match_data()Andy Shevchenko2023-01-081-23/+20
| | | | | | | | | | | | The spi_get_device_match_data() helps to get driver data from the firmware node or SPI ID table. Use it instead of open coding. While at it, switch ID tables to provide an acrual pointers to the configuration data.

* iio: adc128s052: add proper .data members in adc128_of_match tableRasmus Villemoes2022-11-231-7/+7
| | | | | | | | | | | | | | | | | | | Prior to commit bd5d54e4d49d ("iio: adc128s052: add ACPI _HID AANT1280"), the driver unconditionally used spi_get_device_id() to get the index into the adc128_config array. However, with that commit, OF-based boards now incorrectly treat all supported sensors as if they are an adc128s052, because all the .data members of the adc128_of_match table are implicitly 0. Our board, which has an adc122s021, thus exposes 8 channels whereas it really only has two.

* iio: adc: adc128s052: Simplify adc128_probe()Christophe JAILLET2021-10-211-23/+10
| | | | | | | | | | | | | | | Turn 'adc128_probe()' into a full resource managed function to simplify the code. This way, the .remove function can be removed. Doing so, the only 'spi_get_drvdata()' call is removed and the corresponding 'spi_set_drvdata()' can be removed as well.

* iio:adc:ti-adc128s052: drop of_match_ptr protectionJonathan Cameron2020-09-031-1/+2
| | | | | | | | | | | | | | There is no real advantage in having these protections and for parts that do not have an explicit ACPI ID, it prevents the use of PRP0001. I'm trying to clear this out of IIO in general to avoid copying in new drivers. Include mod_devicetable.h as we are using of_device_id in here so including that header is best practice.

* Replace HTTP links with HTTPS ones: drivers/iioAlexander A. Klimov2020-07-131-3/+3
| | | | | | | | | | | | | | | | | | | Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

* iio: Remove superfluous of_node assignmentsLars-Peter Clausen2020-06-141-1/+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.

* iio: remove explicit IIO device parent assignmentAlexandru Ardelean2020-06-141-1/+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.
