From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>


This patch add support to DB600c board, which is another
96boards based on Qualcomm APQ8064 SoC.

Support for USB, HDMI, PCIe, I2C, SPI, eMMC, microSD card, LEDs
device tree nodes is added in this patch.

Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

---
Changes since v1:
	- added chosen node with stdout, suggested by Stephen Boyd
	- removed spi flash node and gpio22 pinconf, as its not required in this patch.
	- removed extra comment lines and fix a node name, spotted by Stephen Boyd.

Hello Srini (I hope you had a nice vacation!)


Running checkpatch on this patch gives a few of these warnings:

WARNING: line over 80 characters

These can probably be ignored, since they exist for most
arch/arm/boot/dts/qcom-*.dts files.


However, it also gives a few of these errors:

ERROR: trailing whitespace

These should probably be fixed, since the are errors and not warnings.


Kind regards,
Niklas
