- * its MAC connected to Port4 of a Marvell MV88E6176 7-port GigE switch via
- * MDIO and RGMII. Ports 0-3 are standard copper RJ45 but Ports 5 and 6
- * connect to Marvell MV88E1111 dual-mode Copper/Fiber PHY's over SGMII and
- * MDIO. The PHY's have both an RG45 for copper and an SFP module.

-The GW54xx PMIC swbst regulator is used for LVDS power, CANbus xceiver
-and HDMI DDC and is enabled by the bootloader. Set the regulator to
-always-on so that Linux doesn't turn it off thinking its not needed.

-Subject: [PATCH 3/3] ARM: dts: imx: ventana: Allow HDMI and LVDS to work
- simultaneously
-
-Currently it is not possible to have HDMI and LVDS working simultaneously,
-because both ports try to use PLL5.
-
-Move the LVDS clock parent to PLL3_USB_OTG, so that HDMI and LVDS can be
-driven from independent sources.
-
-With this change the LDB pixel clock goes to 68.57 MHz, which is still
-within the valid range for the displays supported by the Ventana boards.

-Date: Thu, 15 May 2014 00:29:18 -0700
-Subject: [PATCH] net: igb: add phy read/write functions that accept phy addr
-
-Add igb_write_reg_gs40g/igb_read_reg_gs40g that can be passed a phy address.
-The existing igb_write_phy_reg_gs40g/igb_read_phy_reg_gs40g become wrappers
-to this function.

-Subject: [PATCH] net: igb: register mii_bus for SerDes w/ external phy
-
-If an i210 is configured for 1000BASE-BX link_mode and has an external phy
-specified, then register an mii bus using the external phy address as
-a mask.
-
-An i210 hooked to an external standard phy will be configured with a link_mo
-of SGMII in which case phy ops will be configured and used internall in the
-igb driver for link status. However, in certain cases one might be using a
-backplane SerDes connection to something that talks on the mdio bus but is
-not a standard phy, such as a switch. In this case by registering an mdio
-bus a phy driver can manage the device.
