Yeh, I got patches from him recently for this, but he said he was still having issues... I'm waiting for the Foundation to get a proper spec sheet from NXP for the TDA19988...

Yeh, GPIO1_27 is the one that enables the clock to the HDMI chip and when I was looking over his patch, I didn't see anything for enabling it... This is mentioned in the SRM... Looks like GPIO0_19 isn't necessary as that is the clock for CEC, and we don't need that till later (say use the TV remote as an input device)... -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
