[PATCH 13/16] s5p-jpeg: Allow for wider JPEG subsampling scope for Exynos4x12 encoder

Exynos4x12 supports wider scope of subsampling modes than S5PC210. Adjust corresponding mask accordingly. Signed-off-by: Jacek Anaszewski j.anaszew...@samsung.com Signed-off-by: Kyungmin Park kyungmin.p...@samsung.com --- drivers/media/platform/s5p-jpeg/jpeg-core.c |3 ++- 1 file changed, 2

[PATCH 07/16] s5p-jpeg: Fix lack of spin_lock protection

s5p_jpeg_device_run and s5p_jpeg_runtime_resume callbacks should have spin_lock protection as they alter device registers. Signed-off-by: Jacek Anaszewski j.anaszew...@samsung.com Signed-off-by: Kyungmin Park kyungmin.p...@samsung.com --- drivers/media/platform/s5p-jpeg/jpeg-core.c | 11

[PATCH 09/16] s5p-jpeg: Split jpeg-hw.h to jpeg-hw-s5p.c and jpeg-hw-s5p.c

[PATCH 11/16] s5p-jpeg: Retrieve YCbCr subsampling field from the jpeg header

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. Signed-off-by: Jacek Anaszewski j.anaszew...@samsung.com Signed-off-by: Kyungmin

[PATCH 16/16] s5p-jpeg: Adjust g_volatile_ctrl callback to Exynos4x12 needs

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 decoded_subsampling_to_v4l2, which performs HW - V4L2 translation. Signed-off-by: Jacek Anaszewski j.anaszew

[PATCH 04/16] s5p-jpeg: Remove superfluous call to the jpeg_bound_align_image function

Aligning capture queue image dimensions while enqueuing output queue doesn't make a sense as the S_FMT ioctl might have not been called for the capture queue until that moment, whereas it is required to know capture format as the type of alignment heavily depends on it. Signed-off-by: Jacek

[PATCH] s5p-jpeg: Initialize vfd_decoder-vfl_dir field

which is defined as 0 and uninitialized vfl_dir field is interpreted as such. In effect the unlikely() condition in the v4l_s_fmt function failed for the ioctls that expect is_tx to be false, which prevented the ioctl callbacks registered by the driver from being called. Signed-off-by: Jacek
