The original driver -exists for Davinci VPFE, which is now being changed to Media Controller -Framework. - -Currently the driver has been successfully used on the following -version of Davinci: - - DM365/DM368 - -The driver implements V4L2, Media controller and v4l2_subdev interfaces. Sensor, -lens and flash drivers using the v4l2_subdev interface in the kernel are -supported. - - -Split to subdevs -================ - -The Davinci VPFE is split into V4L2 subdevs, each of the blocks inside the VPFE -having one subdev to represent it. Each of the subdevs provide a V4L2 subdev -interface to userspace. - - DAVINCI ISIF - DAVINCI IPIPEIF - DAVINCI IPIPE - DAVINCI CROP RESIZER - DAVINCI RESIZER A - DAVINCI RESIZER B - -Each possible link in the VPFE is modelled by a link in the Media controller -interface.
