      i2c: i801: Add lis3lv02d for Dell XPS 15 7590 · 2f189493
      Paul Menzel authored
      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.

      i2c: i801: Add lis3lv02d for Dell Precision 3540 · 6d945046
      Paul Menzel authored
      On the Dell Precision 3540/0M14W7, BIOS 1.7.4 05/12/2020, Linux prints
      the warning below.
      
          i801_smbus 0000:00:1f.4: Accelerometer lis3lv02d is present on SMBus but its address is unknown, skipping registration
      
      With the help of Wolfram Sang, the test to probe it on I2C bus 6 at address
      0x29 was successful.
      
          $ echo lis3lv02d 0x29 | sudo tee /sys/bus/i2c/devices/i2c-6/new_device
          [ 2110.787000] i2c i2c-6: new_device: Instantiated device lis3lv02d at 0x29

      So, the device has that accelerometer. Add the I2C address to the
      mapping list.
