Awesome, after a nice holiday break and a workflow upgrade detour, I finally got back into kernel development
Looked at mainline linux and downstream for a while and figured out a few things
- touchkeys are a simple way to start
- cypress,tm2-touchkey is a generic mainline driver that I should put my touchkey support in
- board-<machine> is essentially the dts file. need to manually parse it to convert it into a modern dts
After enabling the touchkey and led regulator, the led turns on!
