iio: accel: bmi088: modified the device name
iio: accel: bmi088: modified the device name
It is possible to have multiple sensors connected on the same platform.
For support of different sensors, making it possible to obtain the
device name by reading the chip id. If the device was found in the
table but the device tree binding is different, the driver will carry
on with a warning. If no matching device was found, the driver load
the binding chip info.
Tested case, test with bmi085 and bmi090 patches applied:
connect 3 bmi090l to the system, and set device tree compatible:
spi2.0: compatible = "bosch,bmi090l-accel";
spi2.2: compatible = "bosch,bmi088-accel";
spi2.4: compatible = "bosch,bmi085-accel";
Get a warning for the mismatched devices:
bmi088_accel_spi spi2.2: unexpected chip id 0x1A
bmi088_accel_spi spi2.4: unexpected chip id 0x1A
Get the real present device name:
/sys/bus/iio/devices/iio:device1/name:bmi090l-accel
/sys/bus/iio/devices/iio:device3/name:bmi090l-accel
/sys/bus/iio/devices/iio:device5/name:bmi090l-accel
