* [media] v4l: vsp1: wpf: Implement rotation supportLaurent Pinchart2017-04-14
| | | | | | | | | Some WPF instances, on Gen3 devices, can perform 90° rotation when writing frames to memory. Implement support for this using the V4L2_CID_ROTATE control.

* [media] v4l: vsp1: Disable cropping on WPF sink padLaurent Pinchart2016-09-19
| | | | | | | | | | Cropping on the WPF sink pad restricts the left and top coordinates to 0-255. The same result can be obtained by cropping on the RPF without any such restriction, this feature isn't useful. Disable it.

* [media] v4l: vsp1: Don't configure RPF memory buffers before calculating offsetsLaurent Pinchart2016-04-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | The RPF source memory pointers need to be offset to take the crop rectangle into account. Offsets are computed in the RPF stream start, which can happen (when using the DRM pipeline) after calling the RPF .set_memory() operation that programs the buffer addresses. The .set_memory() operation tries to guard against the problem by skipping programming of the registers when the module isn't streaming. This will however only protect the first use of an RPF in a DRM pipeline, as in all subsequent uses the module streaming flag will be set and the .set_memory() operation will use potentially incorrect offsets. Fix this by allowing the caller to decide whether to program the hardware immediately or just cache the addresses. While at it refactor the memory set code and create a new vsp1_rwpf_set_memory() that cache addresses and calls the .set_memory() operation to apply them to the hardware. As a side effect the driver now writes all three DMA address registers regardless of the number of planes, and initializes unused addresses to zero.

* [media] v4l: vsp1: rwpf: Don't program alpha value in control set handlerLaurent Pinchart2016-04-13
| | | | | | | | | | | | | | The datasheet clearly states that all but a few registers can't be modified when the device is running. Programming the alpha value in the control set handler is thus prohibited. Program it when starting the module instead. This requires storing the alpha value internally as the module can be started from the frame completion interrupt handler, and accessing control values requires taking a mutex.

* [media] v4l: vsp1: Align crop rectangle to even boundary for YUV formatsDamian Hobson-Garcia2015-07-06
| | | | | | | | | | | | | Make sure that there are valid values in the crop rectangle to ensure that the color plane doesn't get shifted when cropping. Since there is no distinction between 12bit and 16bit YUV formats in at the subdev level, use the more restrictive 12bit limits for all YUV formats.

* [media] v4l2-subdev: replace v4l2_subdev_fh by v4l2_subdev_pad_configHans Verkuil2015-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a subdevice pad op is called from a bridge driver, then there is no v4l2_subdev_fh struct that can be passed to the subdevice. This made it hard to use such subdevs from a bridge driver. This patch replaces the v4l2_subdev_fh pointer by a v4l2_subdev_pad_config pointer in the pad ops. This allows bridge drivers to use the various try_ pad ops by creating a v4l2_subdev_pad_config struct and passing it along to the pad op. The v4l2_subdev_get_try_* macros had to be changed because of this, so I also took the opportunity to use the full name of the v4l2_subdev_get_try_* functions in the __V4L2_SUBDEV_MK_GET_TRY macro arguments: if you now do 'git grep v4l2_subdev_get_try_format' you will actually find the header where it is defined. One remark regarding the drivers/staging/media/davinci_vpfe patches: the *_init_formats() functions assumed that fh could be NULL. However, that's not true for this driver, it's always set. This is almost certainly a copy and paste from the omap3isp driver. I've updated the code to reflect the fact that fh is never NULL.

* [media] v4l: Renesas R-Car VSP1 driverLaurent Pinchart2013-08-18
The VSP1 is a video processing engine that includes a blender, scalers, filters and statistics computation. Configurable data path routing logic allows ordering the internal blocks in a flexible way. Due to the configurable nature of the pipeline the driver implements the media controller API and doesn't use the V4L2 mem-to-mem framework, even though the device usually operates in memory to memory mode. Only the read pixel formatters, up/down scalers, write pixel formatters and LCDC interface are supported at this stage.
