IIRC you removed some > entries for them in your other patchset. I'll look into the R_PIO that can be switched on, but we won't be able to enable that flag on the one where we removed nodes. That would break the old DTs. Thanks! Maxime -- Maxime Ripard, Free Electrons Embedded Linux and Kernel engineering http://free-electrons.com
