I'm not likely to review this, but, this is a _huge_ patch, is there a
way to split it in easier to digest parts?

Please do not use trace_printk in production code [1,2], it is only
meant for debug use. Consider using trace events, or dev_dbg.

we will split the series for areas (e.g: dma, mcu, ..) and make sure each patch compile properly.
