I still don't think exposing this in the DT is necessary (it's hardware block internals), but I'm not writing the code so I'm fine with it either way, really. Regardless, it would be really good to get the slave_sg part of the series in, which is really important for the platform. -------------- next part -------------- A non-text attachment was scrubbed...
