| 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; |
| }; |
