I have applied both patches and the dependency I mention below.
I have also applied the small patch, inlined below, to hook-up
the LAN controller. Unfortunately it doesn't seem to be receiving
any interrupts. Perhaps I am missing something?

The above patch depends on "[1/3] ARM: shmobile: irqpin: fix handling of
spurious interrupts in DT case", right? Has there been any progress in your
discussions with Magnus about what to do about that patch?
