Thank you for the comments.

However, I definitely see the point of specifying ARCH_AT91SAM9RL and worrying about adding additional support for new platforms later, so I'll add that in. > > +/* These values are dependent upon the performance of the ADC.

Since HRT support is not mainline for the SAM9 platforms, I'm going to remove all references to it and worry about high resolution timer support at a later time. > > + /* Remap Register Memory */ > > + res = platform_get_resource(pdev, IORESOURCE_MEM, 0); > > + ts->reg_start = res->start; > > + ts->reg_length = res->end - res->start +1; > > So if no memory resources were passed, this oopses. Ouch, sorry about that. I'll get a check in there. I'll also take care of the whitespace issues and #defines as well. -Justin Waters -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
