charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: "Linux-rockchip" Errors-To: linux-rockchip-bounces+linux-rockchip=archiver.kernel.org@lists.infradead.org From: Chris Morgan 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. Changes Since V2: - Went back to using a new driver on advice from Invensense engineer. - Further split changes up into smaller chunks of functionality. Note still that the largest patch is approximately 900 lines, and that while the driver compiles cleanly at each commit it is not able to drive the hardware until the commit that adds the Interrupt (as it also adds the Makefile). - Change the error to a warning when the devicetree binding does not match the hardware ID. - Dropped the ack on the devicetree bindings, as I am creating a new file (for a new driver) instead of modifying the existing one. Changes Since V3: - Numerous small fixes (too many to list here). Thank you to everyone who provided feedback. - Split power management additions into an additional commit to break things up further. - Consolidated devicetree documentation in existing invensense,icm42600.yaml file. - Removed most of the FIELD_PREP from header file to c files to make code easier to read. - Changed scale values to 2D arrays for Gyro and Accelerometer. - Removed IIO_CHAN_INFO_CALIBBIAS attribute. Changes Since V4: - Additional numerous small fixes, thank you again for all the feedback. - Dropped power control API and instead run device in low noise mode. - Split devicetree bindings into two distinct changes. - Reordered adding of enums and structs to main header file so that they are only brought in when needed. - Stopped using enum for driver data and instead am using pointer to device specific driver data. Changes Since V5: - Corrected use of "dev_warn_probe" to just "dev_warn". - Fixed some return scenarios which would unconditionally return 0 when an error was present. - Corrected use of max() to min() for bounds checking. max() was incorrect. - Fixed using "st->conf.accel.odr" in the gyroscope function. It should have been "st->conf.gyro.odr" which it now is. - Additional small fixes suggested by "sashiko.dev". - Added a regmap cache. I used the datasheet to try and determine which registers might change without explicit writes.
