Yes, I can. ADS7846 needs more definitions in the platform file to work well on spitz. The current platform definition is not sufficient and pointer noise makes it unusable (e. g. 100 pixels jumps). I am comparing Lineo's 2.4 code with 2.6 algorithm and experimenting to get the best results. -- ________________________________________________________________________ Stanislav Brabec http://www.penguin.cz/~utx -- 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/
