I have a strange phenomenon with ADV7619.
Please give me your advice.
When 4k signal with poor quality is inputed to ADV7619, it seems LLC output would be unstable.
But if CP_FORCE_FREERUN(CP map, 0xBF) is set to 1, then LLC output becomes stable.
The register settings for 4k is made based on RecSettings document and eval-board scripts.
Of course, If HD input, CP_FORCE_FREERUN makes free-run.
Do you have any idea why above phenomenon occurs?
When 4k input, does enabling CP_FORCE_FREERUN have any side effect?
