[PATCH v1 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.

[3] http://lava.kernelci.org/scheduler/job/47969/log_file#L_17_11

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

[PATCH v1 1/2] ARM: dts: add cubietech cubieboard4

[tyler.baker-QSEj5FYQhm4dnm+yROfE0A]

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

Add a Cubietech Cubieboard4 device tree and instruct make to build it. This
device tree has been derived from the sun9i-a80-optimus.dts as they are very
similar in design[1]. Notably, I2C3 is not used on Cubieboard4 and the LED/PWM
definitions will need to be updated in the future.

Good catch on the file name.

Actually, you can just use stdout-path, and you can also provide the
baudrate configuration (and reuse the alias you just defined) by using

		stdout-path = "serial0:115200n8";

[PATCH v1 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.
