57387d3c09 iio: accel: bmi088: Add support for bmi090l accel
Add supports for BMI090L, it's a high-performance Inertial
Measurement Unit, with an accelerometer and gyroscope.
The commit adds the accelerometer driver for the SPI interface.
The gyroscope part is already supported by the BMG160 driver.
Same as BMI088, BMI090L have the range of +/-3, 6, 12, and 24g.

7a61456c83 iio: accel: bmi088: Add support for bmi085 accel
Add supports for BMI085, an Inertial Measurement Unit,
with an accelerometer and gyroscope.
The commit adds the accelerometer driver for the SPI interface.
The gyroscope part is already supported by the BMG160 driver.
Unlike BMI088, the BMI085 accelerometer ranges are +/-2, 4, 6,
and 8g, the scales are calculated as 9.8/32768*pow(2,reg41+1).

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

bcf9d61a2d iio: accel: bmi088: Make bmi088_accel_core_remove() return void
Up to now bmi088_accel_core_remove() returns zero unconditionally. Make
it return void instead which makes it easier to see in the callers that
there is no error to handle.

Also the return value of spi remove callbacks is ignored anyway.

c19ae6be75 iio: accel: Add support for the Bosch-Sensortec BMI088
The BMI088 is a combined module with both accelerometer and gyroscope.
This adds the accelerometer driver support for the SPI interface.
The gyroscope part is already supported by the BMG160 driver.
