I don't even see any ethernet devices defined in the omap3430-sdp.dts file.

Well this patch is going to force a gpio restore everytime we call pm_runtime_get() when the use-count is 0. Yes this is not efficient, however, without this patch you run the risk of context being lost and you would never know. Per the changelog, long term a better solution is needed. > I could not git bisect it down to the commit above, had to > manually figure it out..

I am not sure how gpio is related to DMA in this case.
