2022-06-11iio: accel: bmi088: Add support for bmi090l accelLI Qingwu1-0/+7
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.

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).

2022-06-11iio: accel: bmi088: modified the device nameLI Qingwu1-15/+20
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 Signed-off-by: LI Qingwu <Qing-wu.Li@leica-geosystems.com.cn> Link: https://lore.kernel.org/r/20220526133359.2261928-4-Qing-wu.Li@leica-geosystems.com.cn Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2022-06-11iio: accel: bmi088: Make it possible to config scalesLI Qingwu1-1/+32
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.

2022-06-11iio: accel: bmi088: Modified the scale calculateLI Qingwu1-4/+11
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.

2021-10-19iio: accel: bmi088: Make bmi088_accel_core_remove() return voidUwe Kleine-König1-3/+1
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.

The call to pm_runtime_put_noidle() in remove() is not balanced by a get so drop it. Using pm_runtime_resume_and_get() allows for simple introduction of error handling to allow for runtime resume failing.
