io: accel: kxcjk1013: restore the range after resume.

2019-03-09T17:30:14Z

On some laptops, kxcjk1013 is powered off when system enters S3. We need restore the range regiter during resume. Otherwise, the sensor doesn't work properly after S3. Signed-off-by: he, bo Signed-off-by: Chen, Hu Reviewed-by: Hans de Goede Cc: Signed-off-by: Jonathan Cameron

iio: st_accel: use ACPI orientation data

2019-02-02T09:28:51Z

Platform-specific ST accelerometer mount matrix information can be provided by returning a package of 6 integers from the ACPI _ONT method. This has been seen on Acer products such as Veriton Z4860G, Z6860G and A890, which include a ST SMO8840 sensor. We have also confirmed experimentally that the Windows driver uses such information. The _ONT data format was explained by a ST vendor contact. However, strangely enough, the _ONT transformations must be applied after first applying another mount matrix which we determined experimentally. ST have not commented on why this is the case, but we imagine that perhaps earlier devices (before _ONT was introduced) required this translation and hence it became 'standard.' Interpret the _ONT data and export the equivalent mount matrix to userspace. If no _ONT data is present, no mount matrix is exported. Signed-off-by: Daniel Drake Signed-off-by: Jonathan Cameron

iio: accell: mma8452: add vdd/vddio regulator operation support

2019-01-12T19:11:26Z

The accelerometer's power supply could be controllable on some platforms, such as i.MX6Q-SABRESD board, the mma8451's power supplies are controlled by a GPIO fixed regulator, need to make sure the regulators are enabled before any communication with mma8451, this patch adds vdd/vddio regulator operation support.

iio: accel: kxcjk1013: Add KIOX010A ACPI Hardware-ID

2018-11-25T12:35:26Z

Various 2-in-1's use KIOX010A and KIOX020A as HIDs for 2 KXCJ91008 accelerometers. The KIOX010A HID is for the one in the base and the KIOX020A for the accelerometer in the keyboard. Since userspace does not have a way yet to deal with (or ignore) the accelerometer in the keyboard, this commit just adds the KIOX010A HID for now so that display rotation will work.

iio/hid-sensors: Fix IIO_CHAN_INFO_RAW returning wrong values for signed numbers

2018-11-16T11:42:12Z

Before this commit sensor_hub_input_attr_get_raw_value() failed to take the signedness of 16 and 8 bit values into account, returning e.g. 65436 instead of -100 for the z-axis reading of an accelerometer. This commit adds a new is_signed parameter to the function and makes all callers pass the appropriate value for this. While at it, this commit also fixes up some neighboring lines where statements were needlessly split over 2 lines to improve readability.
