Hello I'm trying to get sensors working on my Lenovo Ideapad Yoga 910. I'm running kernel 4.8.8. I did try 4.9-rc5 thinking the ISH support might help, but to no avail. Here's iio-sensor-proxy trying to read the sensors: ** (process:10981): DEBUG: Found als at /sys/devices/pci0000:00/0000:00:15.3/i2c_designware.2/i2c-8/i2c-ITE8186:00/0018:048D:8186.0003/HID-SENSOR-200041.3.auto/iio:device0 ** (process:10981): DEBUG: Found device /sys/devices/pci0000:00/0000:00:15.3/i2c_designware.2/i2c-8/i2c-ITE8186:00/0018:048D:8186.0003/HID-SENSOR-200041.3.auto/iio:device0 of type ambient light sensor at IIO Buffer Light sensor ** (process:10981): DEBUG: Found accel_3d at /sys/devices/pci0000:00/0000:00:15.3/i2c_designware.2/i2c-8/i2c-ITE8186:00/0018:048D:8186.0003/HID-SENSOR-200073.2.auto/iio:device1 ** (process:10981): DEBUG: Found device /sys/devices/pci0000:00/0000:00:15.3/i2c_designware.2/i2c-8/i2c-ITE8186:00/0018:048D:8186.0003/HID-SENSOR-200073.2.auto/iio:device1 of type accelerometer at IIO Buffer accelerometer ** (process:10981): DEBUG: Found associated trigger at /sys/devices/pci0000:00/0000:00:15.3/i2c_designware.2/i2c-8/i2c-ITE8186:00/0018:048D:8186.0003/HID-SENSOR-200073.2.auto/trigger1 ** (process:10981): DEBUG: Got type for in_accel_y: is signed: 1, bytes: 4, bits_used: 16, shift: 0, mask: 0x65535, be: 0 ** (process:10981): DEBUG: Got type for in_accel_x: is signed: 1, bytes: 4, bits_used: 16, shift: 0, mask: 0x65535, be: 0 ** (process:10981): DEBUG: Got type for in_accel_z: is signed: 1, bytes: 4, bits_used: 16, shift: 0, mask: 0x65535, be: 0 ** (process:10981): DEBUG: Built channel array for in_accel_x: index: 0, is signed: 1, bytes: 4, bits_used: 16, shift: 0, mask: 0x65535, be: 0 ** (process:10981): DEBUG: Built channel array for in_accel_y: index: 1, is signed: 1, bytes: 4, bits_used: 16, shift: 0, mask: 0x65535, be: 0 ** (process:10981): DEBUG: Built channel array for in_accel_z: index: 2, is signed: 1, bytes: 4, bits_used: 16, shift: 0, mask: 0x65535, be: 0 ** (process:10981): DEBUG: Found associated trigger at /sys/devices/pci0000:00/0000:00:15.3/i2c_designware.2/i2c-8/i2c-ITE8186:00/0018:048D:8186.0003/HID-SENSOR-200041.3.auto/trigger0 ** (process:10981): DEBUG: Got type for in_intensity_both: is signed: 1, bytes: 4, bits_used: 32, shift: 0, mask: 0x0, be: 0 ** (process:10981): DEBUG: Built channel array for in_intensity_both: index: 0, is signed: 1, bytes: 4, bits_used: 32, shift: 0, mask: 0x0, be: 0 ** (process:10981): DEBUG: Handling driver refcounting method 'ClaimLight' for ambient light sensor device ** (process:10981): DEBUG: Handling driver refcounting method 'ClaimAccelerometer' for accelerometer device ** (process:10981): DEBUG: No new data available on 'iio:device0' ** (process:10981): DEBUG: No new data available on 'iio:device1' ** (process:10981): DEBUG: No new data available on 'iio:device0' ** (process:10981): DEBUG: No new data available on 'iio:device1' It basically reads the accelerometer orientation as 'normal' and never updates it, and the light sensor at 0.0 lux and never updates. I do get this error during boot: [ 2.321857] i2c_hid i2c-ITE8186:00: error in i2c_hid_init_report size:19 / ret_size:18 It would be nice to get them working, is there anything I can do? I have no experience debugging hardware interfaces like these myself, but I'm usually pretty handy - Henry. -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
