i2c: i801: Add lis3lv02d for Dell XPS 15 7590
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.
