[PATCH v2 0/2] ARM: dts: add dts files for Cubieboard4

[tyler.baker-QSEj5FYQhm4dnm+yROfE0A]

From: Tyler Baker <tyler.baker-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>

This series adds basic support for the Cubietech Cubieboard4.

The Cubietech Cubieboard4 is a A80 based development board with 2GB DDR3, 8GB
eMMC, Micro SD, HDMI, VGA, 3.5mm audio jack. One USB OTG port and four USB 2.0
ports.

The sun9i-a80-optimus device tree[1] has been used to boot this board for some
time now, as the two platforms are very similar. But there are differences, so 
it deserves it's own device tree. I've tested this series on a 
Cubieboard4[2][3] and can confirm UART, eMMC, and MMC are working properly.

This patch series is based on arm-soc v4.0-rc2.

Changes v1 -> v2:
* Use more descriptive notation for stdout-path

Changes v0 -> v1:
* Corrected typo. a80-cubietruck -> a80-cubieboard4.
* Removed bootargs node.
* Added stdout-path for uart0.
* Removed unneeded newline.

[PATCH v2 2/2] ARM: dts: add vendor prefix for cubietech

[tyler.baker-QSEj5FYQhm4dnm+yROfE0A]

From: Tyler Baker <tyler.baker-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>

Add a cubietech vendor prefix, as it is missing. The cubietruck, cubieboard2,
and cubieboard all already reference this prefix.
