PATCH 1/1 ARM: dts: imx6qdl-sabreauto: Add HDMI support

From: Fabio Estevam <[email protected]>

Add HDMI support. As the DDC I2C pins are not connected due to pin conflicts, we do not pass the 'ddc-i2c-bus' property in this case.

HDMI works without 'ddc-i2c-bus' property and I2C pins? If not, what's point of this patch.

Yes, HDMI works fine without 'ddc-i2c-bus' property.

'ddc-i2c-bus' property is not mandatory to get HDMI functional.

You can also refer to Documentation/devicetree/bindings/drm/imx/hdmi.txt, which states that ddc-i2c-bus is an optional property.

Okay. Patch applied.

Applied into which tree, please?

Can't find it at:
https://git.kernel.org/cgit/linux/kernel/git/shawnguo/linux.git/

I'm rebasing the branches to v4.2-rc1, and will push them out soon.
