Through investigation, I found the root cause is the change on iommu/intel introduced from v6.12-rc1, from v6.12-rc, the keyboard/trackpad stops working.

[Fix] cherry-pick one patch from upstream. [Test] I patched a Plucky kernel and built it, then shared the deb to bug reporters, they tested with the patched kernel, the spi keyboard/trackpad could work well with this kernel. [Where problems could occur] The change impacts context entry setup order for aliased devices, if there is regression, it will be on intel pci/pcie aliased devices, but the regression chance is very low, since this patch just resotres to the original setup order for aliased devices, it should be safe. And they tested the patched kernel, no new issues were found. Following upgrade to 25.04 the spi keyboard and trackpad are not working on my macbook 10,1.
