Hello Mikhail, With my own branch 3.18.9, I applyed your solution with "patch-3.18.9- rt5" but my Pi2 was not able to boot anymore. So I synced to the latest 3.18.y commit on raspberry linux (https://github.com/raspberrypi/linux/commit/2e529746b6de7633ffd02c27c1f 70a1df30fe243), which is on linux 3.18.10. I updated the "patch-3.18.9- rt5" to fit on the latest kernel and now, All is working well. Let me know if you want the updated RT5 patch for kernel 3.18.10.
