The SHIFT13mi or SHIFTbook tablet device by the German manufacturer
SHIFT contains an STM LSM6DSO IMU declared in the DSDT with the
hardware ID SMOCF00. Add this ID to the ACPI match table so that the
driver binds correctly to this device.
WHO_AM_I register returns 0x6c, confirming LSM6DSO.

Please, for the record also reply with the DSDT excerpt of the device in question, so we will see how it's defined in ACPI. -- With Best Regards, Andy Shevchenko

Hi Andy,

Interestingly it has accelerometer and gyroscope described there. Is the other part already supported? -- With Best Regards, Andy Shevchenko

Checking iio devices: $ cat /sys/bus/iio/devices/iio:device*/name i2c-CPLM3218:00 lsm6dso_gyro lsm6dso_accel Both the gyroscope and accelerometer are shown and recognised. Best regards, Milan Misic

But it has different HID? Can you also cut'n'paste that device description from DSDT? -- With Best Regards, Andy Shevchenko

Hi Andy, the LSM6DSO is a combined unit that only has one hardware ID. The DSDT only has the GYRO node, there is no separate node for the accelerometer. The only other node besides GYRO in that DSDT section is for the ambient light sensor. Best regards, Milan Misic

Ah, right, the third one there is probably touchscreen or touchpad wit the HID CPLM3218. -- With Best Regards, Andy Shevchenko

Hi Andy, The CPLM3218 corresponds to the device's Capella Micro CM3218x ambient light sensor. It is fully functional. Best regards, Milan Misic
