On the Dell XPS 15 7590/0VYV0G, BIOS 1.24.0 09/11/2023, Linux prints the
warning below.
i801_smbus 0000:00:1f.4: Accelerometer lis3lv02d is present on SMBus but its address is unknown, skipping registration
Following the same suggestions by Wolfram Sang as for the Dell Precision
3540 [1], the accelerometer can be successfully found on I2C bus 2 at
address 0x29.
$ echo lis3lv02d 0x29 | sudo tee /sys/bus/i2c/devices/i2c-2/new_device
lis3lv02d 0x29
$ dmesg | tail -5
[ 549.522876] lis3lv02d_i2c 2-0029: supply Vdd not found, using dummy regulator
[ 549.522904] lis3lv02d_i2c 2-0029: supply Vdd_IO not found, using dummy regulator
[ 549.542486] lis3lv02d: 8 bits 3DC sensor found
[ 549.630022] input: ST LIS3LV02DL Accelerometer as /devices/platform/lis3lv02d/input/input35
[ 549.630586] i2c i2c-2: new_device: Instantiated device lis3lv02d at 0x29
So, the device has that accelerometer. Add the I2C address to the
mapping list, and test it successfully on the device.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
