Hey Dave,
This series of patches to add modesetting support for Ampere has been pulled out of a larger, more invasive series. As there's currently no firmware available for us to use, the rest of it isn't important right now, and it'd be nice to have something non-invasive to provide what support we currently can (and is possible to backport to earlier kernels).
No other chipset should be impacted by these patches, as the changes are largely confined to adding Ampere versions of the code handling each IP block.
I'd like to extend thanks to NVIDIA for providing hardware, and for their assistance with confirming/clarifying some of the changes.
Ben.
