What's the rationale for this approach? There's no requirement for the atkbd driver to be used for all keyboards. It seems very obscure (and backward) way to do things. Why not implement the serio driver for the IO level, and a separate keyboard driver which can handle the protocol and interpret the scancodes? -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
