2025-04-22iio: normalize array sentinel styleDavid Lechner2-5/+5
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.

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.

2022-11-23iio: st_sensors: core and lsm9ds0 switch to devm_regulator_bulk_get_enable()Jonathan Cameron1-58/+7
These drivers only turns the power on at probe and off via a custom devm_add_action_or_reset() callback. The two regulators were handled separately so also switch to bulk registration. The new devm_regulator_bulk_get_enable() replaces all this boilerplate code.

2022-01-23iio: st_sensors: don't always auto-enable I2C and SPI interface driversNikita Yushchenko1-6/+22
This patch makes I2C and SPI interface drivers for STMicroelectronics sensor chips individually selectable via Kconfig. The default is kept unchanged - I2C and SPI interface drivers are still selected by default if the corresponding bus support is available. However, the patch makes it possible to explicitly disable drivers that are not needed for a particular target.

2021-09-14iio: st_sensors: remove reference to parent device object on st_sensor_dataAlexandru Ardelean1-2/+0
The idea behind it, is that all devm_ calls in ST sensors are bound to the parent device object. However, the reference to that object is kept on both the st_sensor_data struct and the IIO object parent (indio_dev->dev.parent). This change only adds a bit consistency and uses the reference stored on indio_dev->dev.parent, to enforce the assumption that all ST sensors' devm_ calls are bound to the same reference as the one store on st_sensor_data.

At this point all ST driver remove functions do iio_device_unregister(). This change removes them from them and replaces all iio_device_register() with devm_iio_device_register(). This can be done in a single change relatively easy, since all these remove functions are define in st_sensors.h.

2021-07-24iio: st-sensors: Remove some unused includes and add some that should be thereJonathan Cameron3-2/+5
The st-sensors drivers have changed in structure over time, and includes have not always kept up with this. Let's bring them back to nearer the ideal. Identified with the include-what-you-use tool and careful checking of its suggestions. Note I haven't been particularly aggressive here, so this is just the cases where the include obviously isn't needed rather than the more subtle corners. Note I took the opportunity to add mod_devicetable.h as I generally prefer to see that when acpi or of match tables are present.

2021-05-17iio: st_sensors: Add lsm9ds0 IMU supportAndy Shevchenko6-0/+386
We can utilize separate drivers for accelerometer and magnetometer, so here is the glue driver to enable LSM9DS0 IMU support. The idea was suggested by Crestez Dan Leonard in [1]. The proposed change was sent as RFC due to race condition concerns, which are indeed possible. In order to amend the initial change, I went further by providing a specific multi-instantiate probe driver that reuses existing accelerometer and magnetometer.
