(Unless I'm missing some board specific dependency of RTC. > If so, please correct me.) I don't really like this argument. Why not allow the firmware to decide which devices are relevant and should be handled by the kernel ? And since we are aiming at single kernel config, if I understand things correctly, I can't see anything else than dts that could hold the machine *configuration*. So let's not make all stuff enabled by default, that's not something we want on those mobile device SoCs. We should not be making fine system tuning more difficult than necessary. I'm with Kukjin on this matter and would prefer patches like the $subject patch not be merged. -- Thanks, Sylwester -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
