Subject[PATCH 2/4] ARM: dts: add TOPEET itop elite based board
Message-ID<sb6rL-12n-1@gated-at.bofh.it>
The TOPEET itop exynos 4412 have three versions base board. The
Elite version is the cheap one without too much peripheral devices
on it.

Currently supported are serial console, wired networking(USB),
USB OTG in peripheral mode, USB host, SD storage, GPIO buttons,
PWM beeper, ADC and LEDs.

Missing space after =

Instead of "console=xxxx", put everything here: "serial2:115200n8".

No underscores. Add a name of class to the node names for all keys. Like
"key-home", "key-back".

The TOPEET itop exynos 4412 have three versions base board. The
Elite version is the cheap one without too much peripheral devices
on it.

Currently supported are serial console, wired networking(USB),
USB OTG in peripheral mode, USB host, SD storage, GPIO buttons,
PWM beeper, ADC and LEDs. The WM8960 analog audio codec is also
enabled.

The FIMC is not used for camera currently, I enabled it just for a
colorspace convertor.
