Hi all As some of you will know, soc-camera framework is undergoing a conversion to the v4l2-subdev API. Most of the legacy soc-camera client API has been ported over to v4l2-subdev. Final conversion is blocked by missing functionality in the current v4l2 subsystem. Namely video bus configuration and data format negotiation. And from the progress of respective RFCs it looks like this could take a while to get them into the mainline, which is also understandable, given the amount of work. So, the question is - can we work out a way to finalise the porting yet before the final versions of those RFCs make it upstream? OTOH, we certainly do not want to have to create a solution, which will have to be thrown away completely later. We could decide to 1. make bus configuration optional. If no data provided - use defaults. 2. use something like the proposed imagebus API for data format negotiation. Even if it will be eventually strongly modified for new "Media Controller & Co." APIs, it already exists, so, the time has already been spent on it, and mainlining it will not require much more time. But I'm open to other ideas too. OR 3. use some intermediate solution - something, that we think will later allow an easy enough extension to the new APIs when they appear. Opinions?
