Sure, the naming above is fine. You'd have to export the tsc_common_probe() and put I2C and SPI bits into tsc2005.c/tsc2004.c I'd probably have separate Kconfig entries for TSC2004 and TSC2005 and have the core be invisible module that the former 2 explicitly "select". Does this make sense? Thanks. -- Dmitry
