This Camera Interface is also supported on other Rockchip SoC such as the RK1808, RK3128, RK3288 and RK3288, but for now I've only been able to test it on the PX30, using a PAL format. This driver is mostly based on the driver found in Rockchip's BSP, that has been trimmed down to support the set of features that I was able to test, that is pretty much a very basic one-frame capture and video streaming with GStreamer. This first draft only supports the Parallel interface, although the controller has support for BT656 and CSI2. Finally, this controller has an iommu that could be used in this driver, but as of today I've not been able to get it to work. Any review is welcome.
