### Added
- 50306: IMU Drivers
  "LSM6DSX driver Update from mainline
  - Restores read FIFO in IRQ handler (previously kernel's divide by zero).
  - Turn on accelerometer when tap detection enabled
  - A raw read from accelerometer will disable it (ODR_XL = 0) and turn off tap detection. Needs a target restart or `i2cset -f -y 1 0x6a 0x10 0x60`
  - The lowest sampling frequency for tap detection tested is 104 Hz (normal power mode) however it's more reliable at 416 Hz (high power mode).
