I've been trying to get HDMI up and running on the linux-fslc/mainline kernel (specifically 3.14.14), and there doesn't seem to be a way to use the actual DDC_SDA/SCL lines (e.g. via ROW3/COL3 mux) on the i.MX6Q/D SoCs.
Most of the available EVMs have the DDC i/o share a standard I2C channel, causing issues/tradeoffs with the 100kHz restriction on ddc traffic.
I know this support existed before (though crammed into the HDCP support) on older kernels, but is there a patchset for this support that I'm not finding?
Does someone know if there are plans to support this feature of the i.MX6 in mainline?
