Subject: [RFC] iio: st: Add lsm9ds0 support for gyro accel and magn
Device is an integrated gyro/accel/magn and temperature sensor. The
device has two i2c/spi interfaces: one for the gyro and one for the
accel/magn/temp sensor.
Datasheet: http://www2.st.com/resource/en/datasheet/lsm9ds0.pdf
The patch uses existing iio st_sensor infrastructure and just adds a
bunch of new device IDs and the new register mappings.
Temperature support is not included.
Signed-off-by: Crestez Dan Leonard <leonard.crestez@...el.com>
---
I tested basic reading of values using software triggers and i2c and the values
seems plausible.
I tested lsm9ds0-accel and lsm9ds0-magn separately because I don't know how to
instantiate two iio drivers for the same I2C device using devicetree. Can you
provide a sample of this or is this not currently supported?
It seems to me that the LSM303AGR device has the same problem: it's an
accel+magn combo behind a single I2C address. How is that supposed to be
instantiated? Other supported combo devices seem to have multiple I2C
addresses.
It's also not clear how to properly deal with bits shared between the accel and
magn part like "block data update" or "interrupt polarity".
