udev: Add rules for accelerometer orientation quirks This commit adds a rules file to extract the properties from hwdb to set on i2c IIO devices. This is used to set the ACCEL_MOUNT_MATRIX property on IIO devices, to be consumed by iio-sensor-proxy or equivalent daemon. The hwdb file contains documentation on how to write quirks. Note however that mount information is usually exported in: - the device-tree for ARM devices - the ACPI DSDT for Intel-compatible devices but currently not extracted by the kernel. Also note that some devices have the framebuffer rotation that changes between the bootloader and the main system, which might mean that the accelerometer is then wrongly oriented. This is a missing feature in the i915 kernel driver: https://bugs.freedesktop.org/show_bug.cgi?id=94894 which needs to be fixed, and won't require quirks.

# This file is part of systemd.
#
# The lookup keys are composed in:
# 60-sensor.rules
#
# Note: The format of the "sensor:" prefix match key is a
# contract between the rules file and the hardware data, it might
# change in later revisions to support more or better matches, it
# is not necessarily expected to be a stable ABI.
#
# Match string formats:
# sensor:modalias:<parent device modalias>:dmi:<dmi string>
#
# To add local entries, create a new file
# /etc/udev/hwdb.d/61-sensor-local.hwdb
# and add your rules there. To load the new rules execute (as root):
# systemd-hwdb update
hwdb: use -y option to udevadm trigger to correctly do sysname-match
2017-01-28 13:49:40 +01:00
# udevadm trigger -y `dirname $(udevadm info -n "/dev/iio:deviceXXX" -q path)`

# Allowed properties are:
# ACCEL_MOUNT_MATRIX=<matrix>
#
# where <matrix> is a mount-matrix in the format specified in the IIO
# subsystem[1]. The default, when unset, is equivalent to:
# ACCEL_MOUNT_MATRIX=1, 0, 0; 0, 1, 0; 0, 0, 1
# eg. the identity matrix.
