Merge branch 'dsa2-pdata-prepatory-patches'
Florian Fainelli says: ==================== net: dsa: Preparatory patches This patch series extracts the 4 patches of the larger: net: dsa: Support for pdata in dsa2 while we wait for feedback from Greg KH on the device references. Changes in v2: - rebased properly after the multi-MDIO bus support added to mv88e6xxx ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
