Signed-off-by: Xia Jiang --- v8:jpeg encoder and decoder use separate callbacks instead of repeating the if/else in every callback. improve vidioc_try_fmt() implementation that can be shared by jpeg encoder and decoder. fix the bug of jpeg encoder s_selection implementation. cancel the state of the jpeg encoder. improve jpeg encoder and decoder set default params flow. put the clock names and other datas in a match_data struct. fix the bug of geting correctly quality value. do the all the bits' settings of one register in one function. move the code of mtk_jpeg_enc_reg.h to mtk_jpeg_enc_hw.h and delete mtk_jpeg_enc_reg.h. v7: reverse spin lock and unlock operation in device run function for multi-instance. v6: add space to arounding '+'. alignment 'struct mtk_jpeg_fmt *fmt' match open parenthesis. change 'mtk_jpeg_enc_set_encFormat' to 'mtk_jpeg_enc_set_enc_format'. make 'mtk_jpeg_ctrls_setup' to static prototype. delete unused variables 'jpeg'/'align_h'/'align_w'/'flags'. initialize 'yuv_format'/'enc_quality' variables. v5: support crop for encoder and compose for decoder in s_selection and g_selection function. use clamp() to replace mtk_jpeg_bound_align_image() and round_up() to replace mtk_jpeg_align(). delete jpeg_enc_param/mtk_jpeg_enc_param structure and mtk_jpeg_set_param(), program the registers directly based on the original V4L2 values. move macro definition about hw to mtk_jpeg_enc_reg.h. delete unnecessary V4L2 logs in driver. cancel spin lock and unlock operation in deviec run function. change jpeg enc register offset hex numberals from upercase to lowercase. 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. --- drivers/media/platform/mtk-jpeg/Makefile | 5 +- .../media/platform/mtk-jpeg/mtk_jpeg_core.c | 1038 +++++++++++++---- .../media/platform/mtk-jpeg/mtk_jpeg_core.h | 51
