Subject: [PATCH 1/3] ARM: dts: imx: ventana: set GW54xx PMIC swbst regulator
as always-on
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.

The .get_mctrl callback should not report the status of RTS or LOOP, so
drop this. Instead implement reporting the state of CAR (aka DCD) and
RI.
For .set_mctrl implement setting the DTR line.

Make sure that events that are not handled in the irq function don't
trigger an interrupt.
When the serial port is operated in DTE mode, the events for DCD and RI
events are enabled after a system reset by default.

The i210/i211 uses the MDICNFG register for the phy address instead of the
MDIC register.

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.
