From: Hans Verkuil <hans.verkuil@xxxxxxxxx> This is a v2 patch series of an old patch series from Jose: https://www.mail-archive.com/linux-media@xxxxxxxxxxxxxxx/msg110275.html It's rebased, I updated the documentation and implemented this for the adv7842 which is one of the very few receivers that can detect the received pixelclock frequency with sufficient precision to tell the difference between 60 and 59.94 Hz. I also verified that the adv7604 definitely can NOT do this. Back in March 2017 I promised Jose that I would test this on my setup with a cobalt driver and an adv7842 receiver 'within a week'. Hmmm... Let's just say: better late than never.
