  1. MPC83xx SerDes controller devices
  2. MPC83xx SoCs contain a built-in SerDes controller that determines which
  3. protocols (SATA, PCI Express, SGMII, ...) are used on the system's serdes lines
  4. and how the lines are configured.
  5. Required properties:
  6. - compatible: must be "fsl,mpc83xx-serdes"
  7. - reg: must point to the serdes controller's register map
  8. - proto: selects for which protocol the serdes lines are configured. One of
  9. "sata", "pex", "pex-x2", "sgmii"
  10. - serdes-clk: determines the frequency the serdes lines are configured for. One
  11. of 100, 125, 150.
  12. - vdd: determines whether 1.0V core VDD is used or not
  13. Example:
  14. SERDES: serdes@e3000 {
  15. reg = <0xe3000 0x200>;
  16. compatible = "fsl,mpc83xx-serdes";
  17. proto = "pex";
  18. serdes-clk = <100>;
  19. vdd;
  20. };
