[PATCH 0/4] Apple M1 USB4/Thunderbolt DART support

[Sven Peter]

Hi,

The M1 SoCs have a second slightly different variant of the regular
DART used for the USB4 PCIe ports. It supports 64 instead of 16 streams
which requires a minor change to the MMIO layout.
There seems to be no way to tell them apart from the regular DARTs by
just looking at the DART_PARAMs register so we have to add a new
compatible for those.

Best,

Sven
