I can see that 2972 is currently the alphabetically first supported chip, but that is, in my opinion, irrelevant, and it will change. If/when support for LTC2971 is added to the file and to the driver, do you plan to rename the file again ? Thanks, Guenter

I random pick one. I am not care about filename. If you like, I can use lltc,ltc2978.yaml or other filename.
