Would you mind sending a properly formatted, Signed-off-by patch with this to
the ML? (You might want to read Documentation/SubmittingPatches in the kernel
tree first).

These integrated apple connectors aren't really supported yet, an mmiotrace
from the blob would be useful (See [1] or the docs in the kernel tree for
