[PATCH v4 5/5] media: platform: Add jpeg dec/enc feature

Xia Jiang
2019-10-17T08:43:04Z

Add mtk jpeg encode v4l2 driver based on jpeg decode, because that jpeg
decode and encode have great similarities with function operation.

Signed-off-by: Xia Jiang <xia.jiang@mediatek.com>
---
v4: split mtk_jpeg_try_fmt_mplane() to two functions, one for encoder,
one for decoder.
split mtk_jpeg_set_default_params() to two functions, one for
encoder, one for decoder.
add cropping support for encoder in g/s_selection ioctls.
change exif mode support by using V4L2_JPEG_ACTIVE_MARKER_APP1.
change MTK_JPEG_MAX_WIDTH/MTK_JPEG_MAX_HEIGH from 8192 to 65535 by
specification.
move width shifting operation behind aligning operation in
mtk_jpeg_try_enc_fmt_mplane() for bug fix.
fix user abuseing data_offset issue for DMABUF in
mtk_jpeg_set_enc_src().
fix kbuild warings: change MTK_JPEG_MIN_HEIGHT/MTK_JPEG_MAX_HEIGHT
and MTK_JPEG_MIN_WIDTH/MTK_JPEG_MAX_WIDTH from
'int' type to 'unsigned int' type.
fix msleadingly indented of 'else'.

v3: delete Change-Id.
only test once handler->error after the last v4l2_ctrl_new_std().
seperate changes of v4l2-ctrls.c and v4l2-controls.h to new patch.

v2: fix compliance test fail, check created buffer size in driver.
