Kobo Nia second and/or third revision kernel sources

[tux-linux]

Hello,

We've discovered in this issue (Quill-OS/quill#47) and in previous reports that the Kobo Nia's hardware seems to have changed over time, to the point where it is now causing InkBox OS to get confused and not interact properly with the hardware (especially the power button).
From what we have seen, some PCBs have the serial number 4A2 for the earliest and 4C1 for the newest. If there is a 4Bx, please kindly tell us!
We are wondering if there are any different kernel sources, as the battery chip doesn't seem to be the same as well, neither does the crystal oscillator (though the latter might not be this relevant), for these revisions.

Thanks a lot.

That would be the one with the BD71828 PMIC, matching other hardware revisions that appeared in that lineup (at the very least, I'm aware of it for the Libra 2 & Sage).
