iio: trigger: stm32-lptimer: Fix build warnings about export.h

2025-06-26T18:32:52+00:00

After commit a934a57a42f6 ("scripts/misc-check: check missing #include when W=1") and commit 7d95680d64ac ("scripts/misc-check: check unnecessary #include when W=1") we get the build warning with W=1: drivers/iio/trigger/stm32-lptimer-trigger.c: warning: EXPORT_SYMBOL() is used, but #include is missing Fix it.

iio: normalize array sentinel style

2025-04-22T18:10:04+00:00

Use `\t(\{ ?\},|\{\}|\{\s*/\*.*\*/\s*\},?)$` regex to find and replace the array sentinel in all IIO drivers to the same style. For some time, we've been trying to consistently use `{ }` (no trailing comma, no comment, one space between braces) for array sentinels in the IIO subsystem. Still nearly 50% of existing code uses a different style. To save reviewers from having to request this trivial change as frequently, let's normalize the style in all existing IIO drivers. At least when code is copy/pasted to new drivers, the style will be consistent.

iio: trigger: stm32-lptimer: add support for stm32mp25

2025-04-22T18:09:54+00:00

Add support for STM32MP25 SoC. Use newly introduced compatible to handle this new HW variant. Add new trigger definitions that can be used by the stm32 analog-to-digital converter. Use compatible data to identify them.

iio: Switch to use hrtimer_setup()

2025-02-18T10:19:05+00:00

hrtimer_setup() takes the callback function pointer as argument and initializes the timer completely. Replace hrtimer_init() and the open coded initialization of hrtimer::function with the new setup mechanism. Patch was created by using Coccinelle.

iio: trigger: stm32-timer: add support for stm32mp25

2024-12-28T14:28:14+00:00

Add support for STM32MP25 SoC. Use newly introduced compatible to handle this new HW variant. Add TIM20 trigger definitions that can be used by the stm32 analog-to-digital converter. Use compatible data to identify it. As the counter framework is now superseding the deprecated IIO counter interface (IIO_COUNT), don't support it. Only register IIO trigger devices for ADC usage. So, make the valids_table a cfg option. Signed-off-by: Fabrice Gasnier Link: https://patch.msgid.link/20241220095927.1122782-4-fabrice.gasnier@foss.st.com Signed-off-by: Jonathan Cameron

iio: Switch back to struct platform_driver::remove()

2024-10-10T18:31:50+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/iio/ to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. While touching these files, make indention of the struct initializer consistent in several files.

iio: trigger: stm32-timer: Convert to platform remove callback returning void

2023-09-23T14:06:56+00:00

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
