Subject: [PATCH v2 0/5] Add Invensense ICM42607
Date: Thu, 19 Mar 2026 13:29:36 -0500	[thread overview]
Message-ID: <20260319182956.146976-1-macroalpha82@gmail.com> (raw)

From: Chris Morgan <macromorgan@hotmail.com>

Add support for the ICM42607 IMU. This sensor shares the same
functionality but a different register layout with the existing
ICM42600.

This driver should work with the ICM42607 and ICM42607P over both I2C
and SPI, however only the ICM42607P over I2C could be tested.

Changes Since V1:
 - Instead of creating a new driver, merged with the existing inv_icm42600
   driver. This necessitated adding some code to the existing driver to
   permit using a different register layout for the same functionality.
 - Split changes up a bit more to decrease the size of the individual
   patches. Note that patch 0004 is still pretty hefty; if I need to split
   further I may need to create some temporary stub functions.
 - Used guard() and PM_RUNTIME_ACQUIRE_AUTOSUSPEND() on the new functions
   per Jonathan's recommendations.
