Again sorry for the delay and thanks for your patience. Some general comments: 1) The metadata format FourCC should be added in a separate patch, together with documentation for it. 2) Control IDs, structs used by the userspace, etc. should be defined in a header under include/uapi/linux. Please also check my replies to particular patches for further comments. Best regards, Tomasz
