Hello Greg,
beware that I messed up for the 1st versions of this backport, and then I sent v2 patches that are working correctly. You need to be careful to use only the v2 patch if there is one.
I'm really sorry about that.
Thanks, JB

Burst write with SPI is not working for all icm42600 chips. It was only used for setting user offsets with regmap_bulk_write.
Add specific SPI regmap config for using only single write with SPI.
