Is there? There is some in-tree stuff, but haven't seen any other sign of patches. Having looked a bit at that I get the impression that this DT code has been developed (by Grant I guess) in QEMU only as a proof of concept, and never really tested on a real Versatile hardware unit. These: http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=7390/1 http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=7391/1 make it clear that noone ever tested an MMC card on a Versatile booted on real hardware using DT. And I strongly suspect there are more instances like that, it seems AACI, GPIO and I2C and I guess whatever you cannot test on QEMU is just unsupported. But maybe the majority of Versatile users are on QEMU anyway, I sometimes get that impression :-/ Yours, Linus Walleij -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
