Where did you document the new ABI? There is no DT bindings patch with it.

Patch 4 is the dt bindings patch. I will reorder the patches in any future to make the dt bindings patch 1.

Here is a direct link in case it got lost in mail: https://lore.kernel.org/all/20250729-spi-bus-extension-v1-4-b20c73f2161a@xxxxxxxxxxxxxxx/
