Subject: [PATCH 0/2] net: stmmac: allow sharing MDIO lines

From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>

Two MACs may share MDIO lines to the PHYs. Let's allow that in the
stmmac driver by providing a new device-tree property allowing one MAC
node to reference the MDIO bus defined on a second MAC node.

Bartosz Golaszewski (2):
  dt-bindings: net: snps,dwmac: document the snps,shared-mdio property
  net: stmmac: support shared MDIO
