ARM: dts: sunxi: Fix the LED node names
According to the LED bindings, the LED node names are supposed to be led
plus an optional suffix. Let's fix our users to use that new scheme.

ARM: dts: sunxi: Add mdio bus sub-node to GMAC
The DWMAC binding never supported having the Ethernet PHY node as a
direct child to the controller, nor did it support the "phy" property
as a way to specify which Ethernet PHY to use. What seemed to work
was simply the implementation ignoring the "phy" property and instead
probing all addresses on the MDIO bus and using the first available
one.

The recent switch from "phy" to "phy-handle" breaks the assumptions
of the implementation, and does not match what the binding requires.
The binding requires that if an MDIO bus is described, it shall be
a sub-node with the "snps,dwmac-mdio" compatible string.

Add a device node for the MDIO bus, and move the Ethernet PHY node
under it. Also fix up the #address-cells and #size-cells properties
where needed.

ARM: dts: sunxi: Remove pinctrl groups setting bias
So far we've enabled pull-up and pull-down resistors on GPIOs using a
pinctrl node. Now that the GPIO binding allows for a flag to declare this,
let's switch to it.

This brings us closer to removing all the GPIO pinctrl nodes, which will in
turn allow us to switch the pinctrl strict mode on.

ARM: sunxi: Fix the USB PHY ID detect GPIO properties
While the USB PHY Device Tree mandates that the name of the ID detect pin
should be usb0_id_det-gpios, a significant number of device tree use
usb0_id_det-gpio instead.

This was functional because the GPIO framework falls back to the gpio
suffix that is legacy, but we should fix this.

ARM: dts: sun7i: Remove underscores from nodes names
Some GPIO pinctrl nodes cannot be easily removed, because they would also
change the pin configuration, for example to add a pull resistor or change
the current delivered by the pin.

Those nodes still have underscores and unit-addresses in their node names
in our DTs, so adjust their name to remove the warnings. Use that occasion
to also fix some poorly chosen node-names.

Maxime Ripard 85a8c520ca
ARM: dts: sun7i: Change pinctrl nodes to avoid warning
All our pinctrl nodes were using a node name convention with a unit-address
to differentiate the different muxing options. However, since those nodes
didn't have a reg property, they were generating warnings in DTC.

In order to accomodate for this, convert the old nodes to the syntax we've
been using for the new SoCs, including removing the letter suffix of the
node labels to the bank of those pins to make things more readable.

Chen-Yu Tsai ae265c801f ARM: dts: sun7i: cubieboard2: add axp209 regulator nodes
This patch adds the regulator nodes for the axp209 by including
the axp209 dtsi. As the inputs of these regulators are from the
axp209's PS output, which is basically just a mux over the 2
inputs, it is considered to be unregulated. Thus we do not provide
input supply properties for them.

The regulator names and constraints are based on the board
schematics and the SoC datasheet.

DCDC2 is used as the cpu power supply. This patch also references
it from the cpu node.

Also get rid of axp209 properties already set in axp209.dtsi.
