      powerpc: Add TBI PHY node to first MDIO bus · 22066949
      Andy Fleming 提交于
      Systems which use the fsl_pq_mdio driver need to specify an
      address for TBI PHY transactions such that the address does
      not conflict with any PHYs on the bus (all transactions to
      that address are directed to the onboard TBI PHY). The driver
      used to scan for a free address if no address was specified,
      however this ran into issues when the PHY Lib was fixed so
      that all MDIO transactions were protected by a mutex. As it
      is, the code was meant to serve as a transitional tool until
      the device trees were all updated to specify the TBI address.
      
      The best fix for the mutex issue was to remove the scanning code,
      but it turns out some of the newer SoCs have started to omit
      the tbi-phy node when SGMII is not being used. As such, these
      devices will now fail unless we add a tbi-phy node to the first
      mdio controller.
