Consistency. pr_err is used in this driver. So I'm sticking to it with this patch as well.

But I have to admit that this is currently not top of my priority. Peppe as driver maintainer might have some input here. Is this dev_err vs pr_err a show-stopper for this patch?

Rob, thanks for the review. I'll fix the issues and send an updated patch version.

This patch adds support to configure the STMMAC ethernet driver via device-tree instead of platform_data. Currently, only the properties needed on SPEAr600 are provided. All other properties should be added once needed on other platforms.
