OK... so we only have device tree support for PXA3xx and noone is working on PXA2xx. And now we pile up some more legacy code. Such is life.

Argh! Now you're adding another user for a legacy custom pin control implementation. But if noone is going to modernize PXA2xx what can we do :-/ Yours, Linus Walleij -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
