|
|
|
- * This file handles the board muxing between the Fman Ethernet MACs and
|
|
|
- * the RGMII/SGMII/XGMII PHYs on a Freescale P5040 "Super Hydra" reference
|
|
|
- * board. The RGMII PHYs are the two on-board 1Gb ports. The SGMII PHYs are
|
|
|
- * provided by the standard Freescale four-port SGMII riser card. The 10Gb
|
|
|
- * XGMII PHYs are provided via the XAUI riser card. The P5040 has 2 FMans
|
|
|
- * and 5 1G interfaces and 10G interface per FMan. Based on the options in
|
|
|
- * the RCW, we could have upto 3 SGMII cards and 1 XAUI card at a time.
|
|
|
- *
|
|
|
- * Muxing is handled via the PIXIS BRDCFG1 register. The EMI1 bits control
|
|
|
- * muxing among the RGMII PHYs and the SGMII PHYs. The value for RGMII is
|
|
|
- * always the same (0). The value for SGMII depends on which slot the riser is
|
|
|
- * inserted in. The EMI2 bits control muxing for the the XGMII. Like SGMII,
|
|
|
- * the value is based on which slot the XAUI is inserted in.
|
|
|
- *
|
|
|
- * The SERDES configuration is used to determine where the SGMII and XAUI cards
|
|
|
- * exist, and also which Fman's MACs are routed to which PHYs. So for a given
|
|
|
- * Fman MAC, there is one and only PHY it connects to. MACs cannot be routed
|
|
|
- * to PHYs dynamically.
|
|
|
- *
|
|
|
- *
|
|
|
- * This file also updates the device tree in three ways:
|
|
|
- *
|
|
|
- * 1) The status of each virtual MDIO node that is referenced by an Ethernet
|
|
|
- * node is set to "okay".
|
|
|
- *
|
|
|
- * 2) The phy-handle property of each active Ethernet MAC node is set to the
|
|
|
- * appropriate PHY node.
|
|
|
- *
|
|
|
- * 3) The "mux value" for each virtual MDIO node is set to the correct value,
|
|
|
- * if necessary. Some virtual MDIO nodes do not have configurable mux
|
|
|
- * values, so those values are hard-coded in the DTS. On the HYDRA board,
|
|
|
- * the virtual MDIO node for the SGMII card needs to be updated.
|
|
|
- *
|
|
|
- * For all this to work, the device tree needs to have the following:
|
|
|
- *
|
|
|
- * 1) An alias for each PHY node that an Ethernet node could be routed to.
|
|
|
- *
|
|
|
- * 2) An alias for each real and virtual MDIO node that is disabled by default
|
|
|
- * and might need to be enabled, and also might need to have its mux-value
|
|
|
- * updated.
