Current mainline driver is not available on SPI, but it uses generic regmap interface to access the registers so it shouldn't be hard to make it work with SPI (you would just have to write the .probe() routines). > I have a tested SPI interface based SC16IS762 chip driver. > Would like to know if I can contribute the code to main line kernel. I think you mean the sc16is7x2.c driver by Manuel Stahl and others. I'm pretty sure we don't want to have two drivers for the same device in mainline, especially that the current one uses that generic register API. However, both of those drivers have issues with locking (uart uses spinlocks but I2C/SPI transfers are asynchronous) it would be nice to somehow merge them together to get the best of both. -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
