That took rather longer than I had expected. I had always figured that the default settings for those ports would not suit everybody; it was just a matter of how they could be customized. Options would seem to be: - OLPC carries a small patch which configures the port properly. - A set of configuration options is added allowing the port type to be set when the kernel is configured. - The ports could be changed from the default configuration with a boot-time command-line option. That last option might be what works best for OLPC; those systems seem to need several lines of special boot options anyway. It wouldn't be that hard to hack up...anybody got a better idea? (Of course, option 4 is "OLPC doesn't repurpose i2c ports in strange ways, but I figured it's a bit late for that one :) jon -- To unsubscribe from this list: send the line "unsubscribe linux-fbdev" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
