Subject: [PATCH v11 4/6] media: platform: visconti: add streaming interface for ISP parameters and status
Add support to Image Signal Processors of Visconti's Video Input Interface.
This patch adds two streaming interfaces;
one for passing parameters to the signal processor,
the other for receiving status.
Signed-off-by: Yuji Ishikawa <yuji2.ishikawa@...hiba.co.jp>
---
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; moved to userland library
Changelog v11:
- remove feature VB2_USERPTR from viif_params and viif_stats
- fix strange indents at initializations
- remove a redundant default setting of the ISP: L2_ROI
- update copyright year
