So I'm getting contradictory information. First you say that I need an example in the gpio macsec DT binding yaml document. Now I'm told it should go in the parent. Make up your bloody minds and stop pissing me about. This is why I've given up trying to get this in. Getting a consistent message would be nice, but it seems impossible. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up.
