This patch adds two streaming interfaces; one for passing parameters to the signal processor, the other for receiving status. Signed-off-by: Yuji Ishikawa --- Changelog v2: - Resend v1 because a patch exceeds size limit. Changelog v3: - Adapted to media control framework - Introduced ISP subdevice, capture device - Remove private IOCTLs and add vendor specific V4L2 controls - Change function name avoiding camelcase and uppercase letters Changelog v4: - Split patches because the v3 patch exceeds size limit - Stop using ID number to identify driver instance: - Use dynamically allocated structure to hold HW specific context, instead of static one. - Call HW layer functions with the context structure instead of ID number Changelog v5: - no change Changelog v6: - remove unused macros - removed hwd_ and HWD_ prefix - update source code documentation - Suggestion from Hans Verkuil - pointer to userland memory is removed from uAPI arguments - style of structure is now "nested" instead of "chained by pointer"; - use div64_u64 for 64bit division - vendor specific controls support TRY_EXT_CTRLS - add READ_ONLY flag to GET_CALIBRATION_STATUS control and similar ones - human friendry control names for vendor specific controls - add initial value to each vendor specific control - GET_LAST_CAPTURE_STATUS control is updated asyncnously from workqueue - remove EXECUTE_ON_WRITE flag of vendor specific control - uAPI: return value of GET_CALIBRATION_STATUS follows common rules of error codes - applied v4l2-compliance - Suggestion from Sakari Ailus - use div64_u64 for 64bit division - update copyright's year - remove redandunt cast - use bool instead of HWD_VIIF_ENABLE/DISABLE - simplify comparison to 0 - simplify statements with trigram operator - remove redundant local variables - use general integer types instead of u32/s32 - Suggestion from Laurent Pinchart - moved VIIF driver to driver/platform/toshiba/visconti - change register access: struct-style to macro-style - remove unused type definitions - define enums instead of successive macro constants - remove redundant parenthesis of macro constant - embed struct hwd_res into struct viif_device - use xxx_dma instead of xxx_paddr for variable names of IOVA - literal value: just 0 instead of 0x0 - use literal 1 or 0 instead of HWD_VIIF_ENABLE, DISABLE for register access - use true or false instead of HWD_VIIF_ENABLE, DISABLE for function calls - uAPI: return value of GET_CALIBRATION_STATUS follows common rules of error codes Changelog v7: - remove unused variables - split long statements which have multiple logical-OR and trigram operators Changelog v8: - define constant V4L2_CTRL_TYPE_VISCONTI_ISP for datatype of Visconti specific controls - Suggestion from Hans Verkuil - remove pr_info() - use pm_runtime_get_if_in_use() to get power status Changelog v9: - fix warning for cast between ptr and dma_addr_t Changelog v10: - use parameter buffer instead of vendor specific compound controls - add viif_params interface for passing ISP parameters - add viif_stats interface for passing ISP status - remove parameter validation routine;
