It's just a Kconfig switch, the only issue is that users might not turn it on and for platforms where there's not much driver support they're more likely to not have done so. > > Not sure about the 2410, 2440 and 2443 currently > But would just enabling RUNTIME_PM make any harm to those platforms ? It really shouldn't cause any issues but it seems better to not push people towards it too much when there's not much win yet. What I've been doing with all these patches is leaving any PM that already exists untouched (in so far as it's not buggy). Where there's nothing already and it's all new code I've been using a more modern idiom. I hope that this minimise any impact on existing systems. -- 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
