Hi all, I started working on supporting spi-3wire mode in some STM MEMs drivers and I am facing a tricky issue. Let's consider the driver for LSM303AGR accel device (http://www.st.com/resource/en/datasheet/lsm303agr.pdf). The sensor is configured by default in spi 4 wire mode (BIT 0 in register 0x23) but the package does not export the MISO line for accelerometer. The only way to support spi is to enable 3-wire at bootstrap. I am wondering how to figure out the correct register address since it is not possible to read the device whoami. The only way that come up to my mind is to add a lookup table in st_accel_spi.c based on spi_device_id. Is there something better? Or should I just remove the spi support for LSM303AGR?
