Hi all This is the first early draft of the soc-camera conversion to the videobuf2 API. For this RFC I've trivially split the conversion into core and driver, which, actually, we shouldn't do, because after the core is converted all the soc-camera host drivers are broken. Ideally, we should be adding videobuf2 support in parallel to the existing videobuf1 support, then converting each driver individually, and then removing videobuf1, but I'm not sure, how easy this is going to be... Although, I think, some drivers will be more difficult, than sh-ceu, e.g., pxa270 and omap1 with their support for dma-sg. Also, at least sh.ceu and pxa270 support planar formats, so far I've just put all three buffers in one vb2 plane on sh-ceu, not sure, which disadvantages this has. So far sh_mobile_camera_ceu.c is the only driver I've converted and tested, but it too might need more care, e.g., to properly support the multi-planar configurations. I'mm CC-ing individual driver maintainers / authors with a request to try to comvert their respective drivers to vb2 too. I will be attempting that myself too, as the time permits, but at least someone will have to test that - I don't have all the hardware.
