-Subject: [PATCH] net: dsa: b53: mmap: add phy ops
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Implement phy_read16() and phy_write16() ops for B53 MMAP to avoid accessing
-B53_PORT_MII_PAGE registers which hangs the device.
-This access should be done through the MDIO Mux bus controller.
