I'm a bit confused by your names. What are the new/correct ones now?
Some seem to use the amXX names and some the jXX ones. I've read [1]
and it appears it was suggested to use the am67 names for the device
trees. Esp. because there is already, am62, am64, am65, am68 and
am69 in as names for the device trees.
The TRM you've linked in the cover letter doesn't shed much light
either. It just lists both.
Both names are correct, for other Jacinto devices J721S2 and J784S4, the
industrial variants (AM68, AM69 respectively) and those boards were
announced at a later point of time and since the automotive/J7 variants
were introduced first, the SoC dtsi and files have the J7XX names, for
AM62/AM64 there is no confusion in naming, in this case the initial TRM
itself mentions J722S and AM67 variants with similar capabilities, the
reasoning behind continuing with the J722S name is because the initial
support is being added for J722S EVM (the top marking on the SoC package
populated on the EVM say XJ722SAMW, this can be seen in the schematics
also), please let know if this clarifies the confusion.
Thanks and Regards,
Vaishnav
