You can use "U-Boot" overlays:

make sure to update "bb-cape-overlays" package and that you are using
U-Boot overlays..

can1:

config-pin P9.24 can
config-pin P9.26 can

for can0:

I'm testing this right now:

https://github.com/RobertCNelson/dtb-rebuilder/commit/941d12d5328a268e6070fcd84da57645f035b1b4

config-pin P9.19 can
config-pin P9.20 can

(v4.9.x-ti will be first, followed by v4.14.x-ti/v4.4.x-ti)
