Regarding ADV7482 and ADV7511, I understand that the HDMI connection detection
on the source side and sink side is reflected in the following registers and can be read by I2C.
ADV7482: IO Map address 0x72  CABLE_DET_A_ST
ADV7511: Address 0x42  HPD State
Q) I think chattering occurs when I insert the HDMI cable.
How long does it take for the register value to be reflected correctly?
Please reply as soon as possible.
