Current dts files with 'gpio-led' nodes were manually verified.
In order to automate this process leds-gpio.txt
has been converted to yaml. With this conversion a check
for pattern properties was added. A test with the command
below gives a screen full of warnings like:
arch/arm/boot/dts/rk3188-radxarock.dt.yaml: gpio-leds:
'blue', 'green', 'sleep'
do not match any of the regexes:
'(^led-[0-9a-f]$|led)', 'pinctrl-[0-9]+'
Fix these errors with help of the following rules:
1: Add nodename in the preferred form.
2: Always add a label that ends with '_led' to prevent conflicts
with other labels such as 'power' and 'mmc'
3: If leds need pinctrl add a label that ends with '_led_pin'
also to prevent conflicts with other labels.
patternProperties:
# The first form is preferred, but fall back to just 'led'
# anywhere in the node name to at least catch some child nodes.
"(^led-[0-9a-f]$|led)":

The Tinker Board / S devices use a special chip variant called rk3288-c
and use different operating points with a higher max frequency.
So add the missing operating points for Tinker Board / S devices, also
increase the vdd_cpu regulator-max-microvolt to 1400000 uV so that the
cpu can operate at 1.8 GHz.

The Problem:
On ASUS Tinker Board S, when booting from the eMMC, and there is card
in the sd slot, there are constant errors.
Also when warm reboot, uboot can not access the sd slot
Cause:
Identified by Robin Murphy @ ARM. The Card Detect on rk3288
devices is pulled up by vccio-sd; so when the regulator powers this
off, card detect gives spurious errors. A second problem, is during
power down, vccio-sd apprears to be powered down. This causes a
problem when warm rebooting from the sd card. This was identified by
Jonas Karlman.
History:
A common fault on these rk3288 board, which impliment the reference
design.
When this arose before:
http://lists.infradead.org/pipermail/linux-arm-kernel/2014-August/281153.html
And Ulf and Jaehoon clearly said this was a broken card detect design,
which should be solved via polling
Solution:
Hence broken-cd is set as a property. This cures the errors. The
powering down of vccio-sd during reboot is cured by adding
regulator-boot-on.
This solutions has been fairly widely reviewed and tested.

[Heiko: slightly inaccurate fixes but tinker is a sbc (aka like a Pi) where
we can hopefully expect people not to rely on overly old stable kernels]

Tinker Board and Tinker Board S share most of their components,
so should also not replicate these for each variant.
So move them to a shared dtsi that then can get included by both
boards.
