Subject[PATCH v2] ARM: dts: qcom: Add apq8064 Dragon Board 600c support
Date
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.
