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;
};
