That's the "simple" way of making the conflict go away, but I'm afraid it's really not that simple. Having just looked at the SMC91x definition for realview, it shows that the SMC91x binding, like many of the conversions that the patch in my tree fixes, has been created without a proper understanding of the hardware. To put it simply, it is broken. The binding only allows _one_ register width to be specified, which is completely incorrect: the binding _must_ allow multiple register widths to be specified. This is what SMC91x has always expected: to be told which register access widths it is permitted to make. That must include at least one of 8 or 16 bit accesses, but 32-bit access is optional. The result will be that - despite I've fixed up all the static platform data to be correct, there's no way to fix up the DT binding without inventing a new one. So, deleting the Realview (and other) board files results in platforms that can't use networking - it's worse than that, because the smc91x driver will BUG() as a result of this at boot time. Since the patch in my tree is fixing a regression caused by the broken conversions, I'm not mindful to drop it from the merge window - I actually want to push it into -rc kernels. We _do_ need to fix the DT regressions, and quickly though, and push those with this patch. Since I don't use the SMC91x with DT, that's outside of what I can test, so consider this a call for help on that subject. -- RMK's Patch system: http://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line: currently at 9.6Mbps down 400kbps up according to speedtest.net. -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
