While I've applied other patches in this series I have
not applied this one - mainly to allow this discussion to conclude.
Is an appropriate solution to do the following?
1) Atomically update
a) r8a779{5|6}.dtsi to use "rgmii" and
b) salvator-common.dtsi to use "rgmii-txid"
2) Update this patch to use "rgmii"
Sorry if I'm still missing the point.
