Hw controller is really compatible. Only thing is that there is no physical pins on SoC for KBC-ROW11 to KBC-ROW15. Because, there is no physical pins for ROW11 to ROW15, we asked to remove programming/reference this rows from TRM of T114 to consistent with SoCs. -- 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/
