The driver uses the media controller API and in this initial support implements both of the ISP's capture pipelines allowing a range of output formats plus downscaling and cropping. The capture pipelines are named "Full resolution" and "Downscale" and so abbreviated FR and DS throughout the driver. The driver exposes 4 V4L2 subdevices: - mali-c55 isp: input data formatting - mali-c55 tpg: test pattern generator (modeled as a camera sensor entity) - mali-c55 resizer fr: downscale / crop and format setting for the FR pipe - mali-c55 resizer ds: downscale / crop and format setting for the DS pipe Conspicuously missing from the list are subdevices for the ISP's statistics and parameters; work is progressing in these areas and we plan on introducing them in later series on top of this one.
