[PATCH V5 0/6] iio: accel: bmi088: support BMI085 BMI090L

[LI Qingwu]

Modified the units after application of scale from 100*m/s^2 to m/s^2,
since the units in the ABI documents are m/s^2.
Add supports for the BMI085 accelerometer.
Add supports for the BMI090L accelerometer.
Make it possible to config scales.

Change in v5: 
- Fix the issue of 'undeclared function FIELD_GET'

[PATCH V5 1/6] iio: accel: bmi088: Modified the scale calculate

[LI Qingwu]

The units after application of scale are 100*m/s^2,
The scale calculation is only for the device
with the range of 3, 6, 12, and 24g,
but some other chips have a range of 2, 4, 6, and 8g.

Modified the scales from formula to a list, the scales in the list are
calculated as 9.8/32768*pow(2,reg41+1)*1.5, refer to datasheet 5.3.4.
The new units after the application of scale are m/s^2.

[PATCH V5 2/6] iio: accel: bmi088: Make it possible to config scales

[LI Qingwu]

The sensor can set the scales by writing the range register 0x41,
The current driver has no interface to configure it.
The commit adds the interface for config the scales.

[PATCH V5 3/6] iio: accel: bmi088: modified the device name

[LI Qingwu]

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

[PATCH V5 4/6] iio: accel: bmi088: Add support for bmi085 accel

[LI Qingwu]

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).

[PATCH V5 6/6] dt-bindings: iio: accel: Add bmi085 and bmi090l bindings

[LI Qingwu]

Adds the device-tree bindings for the Bosch
BMI085 and BMI090L IMU, the accelerometer part.

Thank you, Rob, I did check, the most datasheets are part of the tags,
and few of them has a blank line, do you agree to keep it?

Seems we have some disagreement on this.  Personally I thought they'd been
adopted as a standard tag block entry, though I can't immediately find
a clear statement of that.

I've applied this series to the togreg branch of iio.git and pushed
out as testing.

Note I can rebase that tree still (and will do anyway to move to
rc1 or so once available) so we can resolve that question of
whether Datasheet is a tag or not in parallel with letting 0-day
see if it can find anything else we missed.

Thanks,

Jonathan
