[PATCH] platform/x86: dell-lis3lv02d: Add Precision M4800
From: Rosen Penev
Date: Sun Nov 01 2026 - 22:19:46 EST
The Dell Precision M4800 has an accelerometer on the i801 SMBus which
is not described by ACPI, so the driver currently skips it:
dell_lis3lv02d: accelerometer is present on SMBus but its address is unknown, skipping registration
Reading the WHO_AM_I register at address 0x29 returns 0x33 (LIS3DC),
the same address as the sibling Precision M6800. With this entry the
sensor is detected and reports sane values:
lis3lv02d: 8 bits 3DC sensor found
