Hi Andy,
This patchset adds support for i2c and spi on High-Speed and Low speed
connectors on DB410c.
One of the patch fixes the sleep state of existing i2c node.
thanks,
srini
Changes since v1:
- removed useless comment spotted by Stephen Boyd.
- Use absolute names instead of lables for consistency suggested by Stephen Boyd.

arm64: dts: fix i2c pinconf sleep state function
arm64: dts: qcom: Add msm8916 I2C nodes.

This patch fixes the i2c pinctrl sleep state by changing the pinconf
function to be in gpio mode rather than i2c.

This patch adds missing support for i2c0 and i2c6, this support is
required to connect the i2c slaves on LS expansion on DB410c.
