- 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;
- };
