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;
|
|
};
