A new 'chassis-type' root node property has recently been approved for
the device-tree specification, in order to provide a simple way for
userspace to detect the device form factor and adjust their behavior
accordingly.
This patch fills in this property for end-user devices (such as laptops,
smartphones and tablets) based on Allwinner ARM64 processors.

Neither the binding nor the driver make any use of the wakeup-source
property for the AXP803. Remove it.

The anx6345 bridge mandates that the input port is named port@0. Since
we have a unit-address, this implies that we need a reg property with
the same value, but it was found to be missing in the Teres-I device
tree. Make sure it's there.

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.

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.

Teres-I has an anx6345 bridge connected to the RGB666 LCD output, and
the I2C controlling signals are connected to I2C0 bus.
Enable it in the device tree, and enable the display engine, video mixer
and tcon0 as well.

The TERES-I has internal speakers (left, right), internal microphone
and a headset combo jack (headphones + mic), "CTIA" (android) pinout.
The headphone and mic detect lines of the A64 are connected properly,
but AFAIK currently unsupported by the driver.

There is only one pinmuxing available for each I2C controller.
So, move pinctrl for i2c0, i2c1 from board dts files into SoC dtsi.
By moving these pinctrls the i2c1 node from Nanopi A64 just have a
status, which is disabled already so remove the entire node from it.

Enable pwm and add a pretty standard backlight node.
The regulator is always on, but we include it anyway, because it is
required by the binding document.

This typo inverted the meaning of the comment, but the rest of the
comment and the code reveal that the regulator in question needs to be

The pinmux name and label for a specific function should denote which
pingroup it is on, or if there is only one option for the function, have
not enumerating prefix/suffix at all.
The "uart0_pins_a" label is renamed to "uart0_pb_pins" to fit our
current style. The node name "uart0" is also changed to "uart0-pb-pins"
to match.

On usual A64 board design the power of HDMI controller is connected to
DLDO1 of the AXP803 PMIC. If this regulator is shut down, the HDMI
output will be blank. Therefore the simplefb driver should keep this
regulator on.
Add the regulator to all currently available A64 boards' simplefb_hdmi
device node, if the board is capable of outputing HDMI.

Currently all ARM kernels will have s2idle enabled if CONFIG_SUSPEND is
present. In this case if the lid is closed, systemd-logind will enter
s2idle mode by default; however there's no possible wakeup source
defined, so the system will enter a forever idle.
Add the lid itself as a wakeup source, thus the system can wakeup when
the lid is opened.

Originally the name of the DLDO3 regulator on TERES-I is "eDP12", which
is not consistent with other regulator names.
Change it to "vdd-edp", in order to make it more consistent.
