   4 Subject: [PATCH 02/14] SSDK: platform: use of_mdio_find_bus() to get MDIO bus
   5
   6 Kernel has a generic of_mdio_find_bus() which can get the appropriate
   7 MDIO bus based on the DT node.
   8 So, drop the getting MDIO from platform data, which no longer works
   9 in 5.4 and later and use of_mdio_find_bus().
