Samuel Holland 9fdef3c3d8 ARM: dts: sunxi: Use the new r_intc binding
The binding of R_INTC was updated to allow specifying interrupts other
than the external NMI, since routing those interrupts through the R_INTC
driver allows using them for wakeup.

Update the device trees to use the new binding.

ARM: dts: sunxi: Rename nmi_intc to r_intc
The R_INTC block controls more than just the NMI, and it is a different
hardware block than the NMI INTC found in some other Allwinner SoCs, so
the label "nmi_intc" is inaccurate. Name it "r_intc" to match the
compatible and to match the few references in the vendor documentation.

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: sun6i: 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.

ARM: dts: sun6i: 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.

ARM: dts: sun6i: Remove card detect pull-up
Boards usually have an external pull-up on the card-detect signal, so
there's no need to add another one.

This also removes a DTC warning.

ARM: dts: sunxi: Switch MMC nodes away from cd-inverted property
Using the cd-inverted property is not useful when GPIOs are used as card
detects since the polarity can be specified with the usual
GPIO_ACTIVE_(HIGH|LOW) GPIO flags. It has also caused confusion for
U-Boot developers, so migrate all sunxi boards away from cd-inverted.

Chen-Yu Tsai 85d2913614 ARM: dts: sunxi: Remove no longer used pinctrl/sun4i-a10.h header
All dts files for the sunxi platform have been switched to the generic
pinconf bindings. As a result, the sunxi specific pinctrl macros are
no longer used.

Remove the #include entry with the following command:

    sed --follow-symlinks -i -e '/pinctrl\/sun4i-a10.h/D' \
	arch/arm/boot/dts/sun?i*.*

arch/arm/boot/dts/sun9i-a80.dtsi was then edited to remove the extra
empty line.

Hans de Goede b32aea8514 ARM: dts: sun6i: Add sun6i-reference-design-tablet.dtsi
Just like with a13/a23/a33 most a31 tablets are derived from the same
reference design. Add a .dtsi file with all the common bits to avoid
endless copy and pasting of these.

The sun6i-reference-design-tablet.dtsi this commit adds is a copy
of sun6i-a31s-colorfly-e708-q1.dts with a few tablet specific bits
removed / left in sun6i-a31s-colorfly-e708-q1.dts.
