Not a lot has changed this time around, and most of what I was saying in [1] is still valid. Very little has changed code wise (a couple of bug fixes). The series however now carries a bunch of DT updates so that people can actually make use of PCIe on an M1 box (OK, not quite, you will still need [2], or whatever version replaces it). The corresponding bindings are either already merged, or queued for 5.16 (this is the case for the PCI binding). It all should be in a state that makes it mergeable (yeah, I said that last time... I mean it this time! ;-). As always, comments welcome. M.
