I'm working on a generic bit-banging CEC kernel driver for A10s/A20. Those have only one pin exposed. All control and timing is done in software according to the CEC addendum in the HDMI 1.4 specification.
This is unlike in NVidia Tegra for example which has a proper hardware CEC controller. --Vladimir On 2 October 2014 20:29, [email protected] <[email protected]> wrote: > I > > On Thu, Oct 2, 2014 at 1:19 PM, Christian Ege <[email protected]> wrote: > > During a quick search I had not been able to find any HDMI CEC driver.
