Subject: [RFC PATCH v2 0/4] net: ethernet: Add support for gmii2rgmii converter
Date: Mon, 4 Jul 2016 14:34:40 +0530 [thread overview]
Message-ID: <1467623084-15471-1-git-send-email-appanad@xilinx.com> (raw)
This patch series does the following
---> Add support for gmii2rgmii converter.
---> Add support for gmii2rgmii converter in the macb driver.
The Gigabit Media Independent Interface (GMII) to Reduced Gigabit Media
Independent Interface (RGMII) core provides the RGMII between RGMII-compliant
Ethernet physical media devices (PHY) and the Gigabit Ethernet controller.
This core can be used in all three modes of operation(10/100/1000 Mb/s).
The Management Data Input/Output (MDIO) interface is used to configure the
Speed of operation. This core can switch dynamically between the three
Different speed modes by configuring the conveter register through mdio write.
The conveter sits b/w the MAC and external phy like below
MACB <==> GMII2RGMII <==> RGMII_PHY
MDIO <========> GMII2RGMII
MCAB <=======>
<========> RGMII
Using MAC MDIO bus we can access both the converter and the external PHY.
We need to program the line speed of the converter during run time based
On the external phy negotiated speed.
