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