This driver works on devices with Intel integrated sensor hub, where hinge sensor is presented using a custom sensor usage id. Here the angle is presented in degrees, which is converted to radians. Changes since v3: - hid-sensor-custom: remove sensor_inst::custom_pdev_exposed. - hid-sensor-custom: use static buf, w_buf to avoid using goto in get_known_custom_sensor_index. - hid-sensor-custom-intel-hinge: use devm_ prefix function instead. - sysfs-bus-iio: put in_anglY_raw together with in_angl_raw. Changes since v2: - use 1 iio device instead of 3 for hinge sensor. - use indexed channel instead of modified channel and added channel labels. - remove 2,3 patch in last version, add a document patch to describe the hinge channels. - hid-sensor-custom: use meaningful return value in get_known_custom_sensor_index and checked in call side. - hid-sensor-ids.h: use HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE(x) to define custom sensor value.
