Sadly post v4.18.x the uio-pru driver on mainline is broken for "uio".. Around the same time Roger from TI posted his first pass at remoteproc for mainline, so I've been focusing on that instead. RFC 2 was just posted today: https://marc.info/?l=linux-omap&m=154929024724527&w=2 PS, last week another user asked about uio on v4.19.x too.. So we have 2 users asking about it.. Last i looked at it we need to revert all the uio changes back down to v4.17.x... I don't think i'll have time to personally hack this up, (projects for Embedded World). I think zmatt on beagleboard irc was going to look at it.
