HDMI EDID

jas-rk

I noticed in the firefly-rk3288.dts that i2c5 is disabled although the schematics shows it is wired for support. Does this mean that its not possible to get EDID for HDMI? The reason for my question is because with my test 3.14 kernel I'm not seeing any valid EDID information returned from the hdmi driver and wanted to know if EDID should be possible for HDMI.

Well, I found out the answer myself?by turning on i2c5 it can detect EDID on my kernel.




Another question is VGA mapped to lcd0 and HDMI to lcd1 under Android ?
