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.

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.

The allwinner,pull property set to NO_PULL was really considered our
default (and wasn't even changing the default value in the code).
Remove these properties to make it obvious that we do not set anything in
such a case.

The Colombus development kit uses an optional 2048x1536 edp panel using
an anx9804 parallel lcd to edp converter. The anx9804 chip is controlled
via an i2c bus which is connected to 2 regular gpio pins.

The FSF address triggers a warning on checkpatch, saying that the FSF

Remove it from our DT, as suggested.

Add UART aliases and stdout-path property for all the Allwinner boards so that
we won't have to rely on the bootargs' console= value, while working with
legacy bootloaders.
While we're at it, also remove the mentions of earlyprintk in the bootargs,
that will remove our default bootargs entirely, and allow the kernel to boot on
a system even if DEBUG_LL is configured for another system.

The current GPL only licensing on the DTSI makes it very impractical for other

In order to make it easier for them to reuse our device trees, relicense our

The A31 Colombus board has 3 I2C controllers that should be usable. However,

This platform from WITS is the evaluation board for the Allwinner A31.
It features a quad-Cortex A7, 2048MB of RAM, NAND, USB, MMC, several
UART, HDMI, a 2048 x 1536 10" screen, powered by a PowerVR, etc.
Of course, most of these peripherals aren't supported yet, but support
for those will come eventually.
