+The GW54xx PMIC swbst regulator is used for LVDS power, CANbus xceiver

+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.

+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.
