#1485810 — [PATCH v7 2/3] ARM: dts: add TOPEET itop elite based board

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.

Looks good to me, for the record:

Reviewed-by: Krzysztof Kozlowski <krzk@kernel.org>

You don't need to resend the third patch. Rob took it.

Best regards,
Krzysztof
