This patch adds core dtsi file for Rockchip RK3399 SoCs.
The RK3399 has big/little architecture, which needs a separate
node for the PMU of each microarchitecture, for now it missing
the pmu node since the old one could not work well.

The GeekBox contains an MXM3 module with a Rockchip RK3368 SoC.
Some connectors are available directly on the module.
This adds initial support, namely serial, USB, GMAC, eMMC, IR and TSADC.

Only one of "broken-cd" and "non-removable" should be supplied
according to Documentation/devicetree/bindings/mmc/mmc.txt.
Obviously emmc and sdio-wifi are non-removable devices, while
broken-cd is for removable device whose card detect pin is broken.

Keyboard driver for GPIO buttons(gpio-keys) checks for the legacy
"gpio-key,wakeup" boolean property to enable gpio buttons as wakeup
source.
Few dts files assign value "1" to gpio-key,wakeup and in one instance a
value "0" is assigned probably assuming it won't be enabled as a wakeup
source. Since the presence of the boolean property indicates it is
enabled, value of "0" have no value.
This patch replaces the legacy "gpio-key,wakeup" with the unified
"wakeup-source" property which inturn fixes the above mentioned issue.

In general, the logic voltage is affected by ddr frequency factors.
We should fix the correct voltage range since assuemd that we have the
ddr frequency driver in mainline.
AFAIK, the 1.8v voltage is used by the SD3.0 card.

The pulse-width modulator (PWM) feature is very common in

In general, the pwm pins can via the pinctrl to

Since the two CPU clusters, with four CPU core for each cluster,
one cluster is optimized for high-performance(big cluster) and the othe
is optimized for low power(little cluster).

The idle-states bindings mandate that the entry-method string
in the idle-states node must be "psci" for ARM v8 64-bit systems,
but the examples in the bindings report a wrong entry-method string.
Owing to this typo, some dts in the kernel wrongly defined the
entry-method property, since they likely cut and pasted the example
definition without paying attention to the bindings definitions.
This patch fixes the typo in the DT idle states bindings examples and
respective dts in the kernel so that the bindings and related dts
files are made compliant.

In terms of peripherals the rk3368 is quite similar to the rk3288, which
makes it possible to have a lot basic components working in the first go.
More to follow once I tracked down all the tiny differences that still
exist in some parts.
With these dts files, the R88 board is able to boot from an attached
usb device and most likely from its emmc too, if the emmc uses a standard
partition table instead of Rockchip's own one - the emmc itself is
detected correctly.
