Canbus Hat support
I'm glad there's a lot of effort by the Up team to make Raspberry Pi Hats compatible, but I'm not clear on what is involved. I'm interested in the Up for a relatively low-volume product, but the only thing missing is canbus support. We can make a simple canbus hat that uses an MCP2515 via SPI that the Raspberry Pi supports, but I don't know if that would require driver work by the Up team. Does Linux on the Up use the arm device tree driver infrastructure, or does each hat have to be ported individually?
