Hi! Thank you for the series and sorry to answer as a new mail, just subscribed to the list and didn't manage to retrieve archives (seems VGER doesn't have them). So, regarding to enabling UP Board and similar open connected boards (Galileo, Edison/Arduino, etc.). The mentioned boards are x86. There is currently no way to handle pinctrl on them since they are ACPI-based. Moreover pinctrl doesn't have a way to configure stuff for customer needs! What is my vision on the issue. Currently we have pending ACPI patches from Octavian that help us to load ACPI DSDT overlays in a way as it works for DT. This will make possible to create a blob to configure pins. Thus, part of the patch series which hard codes the mappings is not needed. And therefore your drivers should go somewhere under drivers/pinctrl/intel folder which Mika (mostly) and I are supporting. We still need to agree on the above: which folder and how those drivers should look like. P.S. Dan, next time please include me and Mika into Cc list for such things. Thanks! -- With Best Regards, Andy Shevchenko -- To unsubscribe from this list: send the line "unsubscribe platform-driver-x86" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
