From 5fe419ef2a6154e83aab04c65ec906fef96eb5be Mon Sep 17 00:00:00 2001 From: Ye Li Date: Sun, 3 May 2020 22:41:14 +0800 Subject: net: Add eth phy generic driver for shared MDIO For dual ethernet controllers, the HW design may connect ETH phys to one MDIO ports. So two different ethernet drivers have to share MDIO bus. Since two ethernet drivers are independent, we can't ensure their probe order. To resolve this problem, introduce an eth phy generic driver and uclass. After eth-uclass binds, we search the mdio node and binds the phy node with the eth-phy-generic driver. When one eth driver get its phy device, the parent of phy device will probe prior than phy device. So this ensure the eth driver ownes the MDIO bus will be probed before using its MDIO.
