Hi Kees, Do you have the time/energy to resume the effort of updating the periph/spi interface in where Hauke left off in https://github.com/RIOT-OS/RIOT/pull/4780?
There are a lot of device drivers which need updating, and also some existing comments on the PR. I can assist in reviewing the changes and updating device drivers, but I don't have a lot of time to spend on this right now.
