2019-07-27iio: move 3-wire spi initialization to st_sensors_spiDenis Ciocca
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.

2019-07-27iio:pressure: device settings are set immediately during probeDenis Ciocca
This patch set pressure settings right after probe start. This is done in preparation of regmap that needs different configuration based on multiread bit value. Signed-off-by: Denis Ciocca <denis.ciocca@st.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
