OK, I've reproduced the problem now, and is indeed real. I'll whip up a patch. The very very odd thing is that imx31-dt.c is only compiled if CONFIG_MACH_IMX31_DT, and imx_v6_v7_defconfig doesn't specify a value for that option, so it's disabled when I "make imx_v6_v7_defconfig". If I manually enable the option via "make menuconfig", then I do see this problem. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
