I took a look at the datasheet and at least from the provided timing diagrams, these are both required in SPI mode. http://invensense.tdk.com/wp-content/uploads/2020/09/DS-000292-ICM-42605-v1.5.pdf That doesn't make the binding wrong as such, but we could be tighter in checking this! I'll add this to my list to take a closer look at sometime soonish. Thanks.
