We want to be able to include some other system headers in phy.h but that requires us to have included common.h in the top-level first. Also, common.h includes config.h as the first thing it does, so don't include it directly. Series-to: u-boot Series-cc: Grygorii Strashko <grygorii.strashko@ti.com> Seried-cc: ti Series-process-log: sort, uniq Cover-letter: Prepare for net: phy: prevent uclass_eth device "node" field overwriting Prepare for [1] so that it doesn't break the build for a bunch of boards. There are a number of reasons this series broke the build but none of them depend on changes in the series, so fix up those situations ahead of applying that series.
