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

[Randy Li]

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-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>

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

Best regards,
Krzysztof

[PATCH v7 1/3] ARM: dts: Add TOPEET itop core board SCP package version

[Randy Li]

The TOPEET itop is a samsung exnynos 4412 core board, which have
two package versions. This patch add the support for SCP version.

Currently supported are USB3503A HSIC, USB OTG, eMMC, rtc and
PMIC. The future features are in the based board. Also MFC and
watchdog have been enabled.
