2019-08-05iio: remove get_irq_data_ready() function pointer and use IRQ number directlyDenis Ciocca1-8/+1
Not even sure why it was there since the beginning. Just use IRQ number in the sensor_data struct. Signed-off-by: Denis Ciocca <denis.ciocca@st.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2019-07-27iio: make st_sensors drivers use regmapDenis Ciocca1-77/+23
This patch is meant to replace the i2c/spi transfer functions with regmap. SPI framework requires DMA safe buffers so let's add GFP_DMA flag for memory allocation used by bulk_read functions.

2019-07-27iio: move 3-wire spi initialization to st_sensors_spiDenis Ciocca1-2/+63
Some devices need to be configured with special bit in order to use spi 3-wire. This was done during device identification phase. Instead, let's move this part as spi specific. Doing this the check_device_support function becomes a simple device id check, so let's rename it.

2019-05-30treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 177Thomas Gleixner1-2/+1
Based on 1 normalized pattern(s): licensed under the gpl 2 extracted by the scancode license scanner the SPDX license identifier GPL-2.0-only has been chosen to replace the boilerplate/reference in 135 file(s).
