[PATCH 0/4] inv_icm42600 driver enhancements

From: Jean-Baptiste Maneyrol via B4 Relay

Date: Thu Aug 20 2026 - 15:08:24 EST


This series add enhancements patches to inv_icm42600 driver.

It includes:
1. Move of MEMS stabilization sleep before FIFO configuration to avoid
pushing incorrect data.
2. Use a fixed FIFO frame of 16 bits to avoid a bug of dynamic FIFO
configuration changed triggered by the sleep move.
3. Simplify watermark computation using gcd.
4. Enhance support of high frequency streaming by avoiding read of FIFO
count for watermark interrupt.
