The updated dtc emits a warning for the edp-panel of two rk3288 boards:
Warning (graph_endpoint): /dp@ff970000/ports/port@1/endpoint: graph node unit address error, expected "0"
Fix this by adding the necessary @0 to the endpoint node.

For veyron the binding should provide both PWM timings, the delay between
you enable the PWM and set the enable signal, and the delay between you
disable the PWM signal and clear the enable signal. Update the binding
accordingly, in this case the panels connected to the veyron boards have
a symmetric power sequence, hence the same value is used.

This was used out-of-tree as a hack for resolving issues where some
systems expect the backlight to turn on automatically at boot, while
others expect to manage the backlight status via a DRM/panel driver.
Those issues have since been fixed upstream in pwm_bl.c without device
tree hacks, and so this un-documented property should no longer be
useful.

Use macros to describe gpios will make the dts easier to
read and write.
All the modifications done with sed:
sed -i -e 's/ 0 GPIO_ACTIVE_/ RK_PA0 GPIO_ACTIVE_/' arch/arm/boot/dts/rk*
sed -i -e 's/ 1 GPIO_ACTIVE_/ RK_PA1 GPIO_ACTIVE_/' arch/arm/boot/dts/rk*
sed -i -e 's/ 2 GPIO_ACTIVE_/ RK_PA2 GPIO_ACTIVE_/' arch/arm/boot/dts/rk*

sed -i -e 's/ 31 GPIO_ACTIVE_/ RK_PD7 GPIO_ACTIVE_/' arch/arm/boot/dts/rk*
Tested with:
for i in dts-old/*dtb; do scripts/dtc/dtx_diff $i dts-new/$(basename $i); done

After hooking up panel and backlight informations, enable the
edp on veyron chromebooks now.

Many Veyron chromebooks share the same panel type, so define the core
settings for all of them and allow the few runaways to override it later.

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.

This adds the shared devicetree files for the Veyron device family.
They are split, as not all veyron devices are chromebooks and
not all contain a sd-card slot.
