I must have started developing the driver based on an initial version of the specs and did not modify naming to the updated ones. Will be fixed in the driver I'll provide for upstream integration.
As for the 'work done' flag: this is something I found out tracking the register (already described
somewhere in this thread) and which is currently being worked on to get integrated into the data sheet update by Bitmine. They are currently in the final steps of ramping up production, so please be patient for that.
OK - thank you! I think I saw that original post a long time ago and then failed to recall it

The chip chain partitioning comment there is also a good one. I currently have a four chip chain in my board (just got it back, am testing it now), I will look at partitioning that in the next revision.
