We know about the existence of DT and the constant migration process that is taking place towards it. Moreover we are strongly interested in converting the Visstrim SM10 platform to DT. Unfortunately, there are several issues that need to be solved so that Visstrim M10 can be fully converted to DT: - full SoC camera DT support - DT support for ov7670 - pinctrl support for i.MX27 Furthermore, we have limited resources at the moment and we have to decide priorities. But having an hybrid platform-DT support is our next task for Visstrim M10. However, I understand your concern about new drivers having DT support. Maybe a good approach could be that I added compile-tested only DT support for this driver and remove platform support for mainline submission (although we maintain it internally in our repositories). What do you think? Regards. -- Javier Martin Vista Silicon S.L. CDTUC - FASE C - Oficina S-345 Avda de los Castros s/n 39005- Santander. Cantabria.
