2022-09-21iio: pressure: st_pressure: Add support for LPS22DFMartyn Welch1-0/+2
Add support for ST LPS22DF pressure sensor. Datasheet: https://www.st.com/resource/en/datasheet/lps22df.pdf Signed-off-by: Martyn Welch <martyn.welch@collabora.co.uk> Link: https://lore.kernel.org/r/20220909161611.780720-2-martyn.welch@collabora.co.uk Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2021-07-24iio: pressure: st_pressure: use devm_iio_triggered_buffer_setup() for bufferAlexandru Ardelean1-5/+0
The st_press_allocate_ring() function calls iio_triggered_buffer_setup() to allocate a triggered buffer. But the same can be done with devm_iio_triggered_buffer_setup() and then the st_press_common_remove() no longer needs to manually deallocate it. We know that the parent of the IIO device is used to manage other instances of the devm unwind, so it can be used in the st_press_allocate_ring() as well.

2019-12-29iio: pressure: st_press: Mark default_press_pdata with __maybe_unusedAndy Shevchenko1-1/+1
Since we put static variable to a header file it's copied to each module that includes the header. But not all of them are actually used it. Mark default_press_pdata with __maybe_unused to calm a compiler down: In file included from drivers/iio/pressure/st_pressure_spi.c:18: drivers/iio/pressure/st_pressure.h:40:46: warning: ‘default_press_pdata’ defined but not used [-Wunused-const-variable=] 40 | static const struct st_sensors_platform_data default_press_pdata = { | ^~~~~~~~~~~~~~~~~~~ ...
