[PATCH v2 0/4] arm64: dts: qcom: add support to LS and HS connectors

[Srinivas Kandagatla]

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.
  arm64: dts: apq8016-sbc: enable i2c buses on LS and HS
  arm64: dts: apq8016-sbc: enable spi buses on LS and HS

[PATCH v2 1/4] arm64: dts: fix i2c pinconf sleep state function

[Srinivas Kandagatla]

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

[PATCH v2 2/4] arm64: dts: qcom: Add msm8916 I2C nodes.

[Srinivas Kandagatla]

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