The idea was to add if-endif clause here for features possibly added sometime in future. But using normal "depends on I2C_DESIGNWARE_PLATFORM" shall make the config depicted as an indented sub-config as well. Would you like me to remove the if-clause and use the depends on operator instead? -Sergey > > Jarkko
