Subject: [PATCH] platform/x86: dell-lis3lv02d: Add Precision 3551
Date: Thu, 10 Jul 2025 21:09:19 +0200 [thread overview]
Message-ID: <20250710190919.37842-1-kernel@aiyionpri.me> (raw)
This marks 0x29 as accelerometer address on Dell Precision 3551.
I followed previous works of Paul Menzel and Hans de Goede to verify it:
$ cd /sys/bus/pci/drivers/i801_smbus/0000\:00\:1f.4
$ ls -d i2c-?
i2c-0
$ sudo modprobe i2c-dev
$ sudo i2cdetect 0
WARNING! This program can confuse your I2C bus, cause data loss and worse!
I will probe file /dev/i2c-0.
I will probe address range 0x08-0x77.
Continue? [Y/n] Y
