* | [media] s5p-jpeg: exynos3250: fix erroneous reset procedureJacek Anaszewski2015-03-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | The first while loop in the function exynos3250_jpeg_reset had no chance to be executed because the reg variable was initialized to 0. Initialize reg variable to 1 to fix the issue.

* [media] vb2: stop_streaming should return voidHans Verkuil2014-04-231-3/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | The vb2 core ignores any return code from the stop_streaming op. And there really isn't anything it can do anyway in case of an error. So change the return type to void and update any drivers that implement it. The int return gave drivers the idea that this operation could actually fail, but that's really not the case. The pwc amd sdr-msi3101 drivers both had this construction: if (mutex_lock_interruptible(&s->v4l2_lock)) return -ERESTARTSYS; This has been updated to just call mutex_lock(). The stop_streaming op expects this to really stop streaming and I very much doubt this will work reliably if stop_streaming just returns without really stopping the DMA.

* [media] s5p-jpeg: Adjust g_volatile_ctrl callback to Exynos4x12 needsJacek Anaszewski2013-12-181-6/+23
| | | | | | | | | | | | | Whereas S5PC210 device produces decoded JPEG subsampling values that map on V4L2_JPEG_CHROMA_SUBSAMPLNG values, the Exynos4x12 device doesn't. This patch adds helper function s5p_jpeg_to_user_subsampling, which performs suitable translation.

* [media] s5p-jpeg: Ensure setting correct value of the chroma subsampling controlJacek Anaszewski2013-12-181-0/+35
| | | | | | | | | | | | | | | | Exynos4x12 has limitations regarding setting chroma subsampling of an output JPEG image. It cannot be lower than the subsampling of the raw source image. Also in case of V4L2_JPEG_CHROMA_SUBSAMPLING_GRAY option the source image fourcc has to be V4L2_PIX_FMT_GREY. This patch implements try_ctrl callback containing mechanism that prevents setting invalid value of the V4L2_CID_JPEG_CHROMA_SUBSAMPLING control.

| | | | | | | | | | | | | | | | When output queue fourcc is set to any flavour of YUV, the V4L2_CID_JPEG_CHROMA_SUBSAMPLING control value as well as its in-driver cached counterpart have to be updated with the subsampling property of the format so as to be able to provide correct information to the user space and preclude setting an illegal subsampling mode for Exynos4x12 encoder.

| | | | | | | | | | | | | | Adjust capture format to the Exynos4x12 device limitations, according to the subsampling value parsed from the source JPEG image header.

| | | | | | | | | | | | | | | | | | | | | Make s5p_jpeg_parse_hdr function capable of parsing "YCbCr subsampling" field of a jpeg file header. Store the parsed value in the context. The information about source JPEG subsampling is required to make validation of destination format possible, which must be conducted for exynos4x12 device as the decoding process will not succeed if the destination format is set to YUV with subsampling lower than the one of the source JPEG image. With this knowledge the driver can adjust the destination format appropriately.
