HDMI CEC

sghazagh

Hi guys,
I just searched a lot and finally found this post about RK3288 CEC for HDMI.
Can you guys please explain a little bit more how exactly we should enable CEC to work with HDMI on our device?
Where are these GPIOs?
How we should solder them and do we need to add all the changes in mentioned commits by our self and recompile the kernel again?
Does the CEC include by default or not?

Many thanks...

Guys,
I have modified the " kernel/arch/arm/boot/dts/rk3288-box.dts" code and enabled the HDMI CEC by changing the line:
hdmi_cec = <0>; to hdmi_cec = <1>;and recompiled the kernel.
So, I have flashed the new generated "kernel.img" and "resource.img" into my RK3288 device and nothing happened.
CEC didn't get enabled!!!

Can you PLEASE let us know how we can enable CEC for HDMI?
What I  have done wrong which the CEC didn't get enabled? Should I do anything else to make it works?

Many thanks....
