I have boards that support Mikrobus - some of the SolidRun products do. I have several Mikrobus "click" boards. This help text seems to imply that Mikrobus click boards include an EEPROM that identify them, hence you make the support for mikroBUS depend on it. No, this is not the case - the click boards do not contain a 1-wire EEPROM. Please fetch a copy of the official Mikrobus specification which is available here: https://download.mikroe.com/documents/standards/mikrobus/mikrobus-standard-specification-v200.pdf and rather than creating something that is implementation specific but appears to be generic, create something that is generic with implementation specific extensions. You'll find if you search that document, no mention is made of an "eprom". "identification" is also not found. "one wire", "onewire", "1-wire", "1wire" are also not found. What I'm concerned about is if we create this "Mikrobus" subsystem which appears to be dependent on one-wire EEPROMs somewhere in the system, and then end up with a load of drivers for various mikroBUS boards, what about cases where there is no one-wire EEPROM? -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up.
