Acked-by: Helen Koike Signed-off-by: Nícolas F. R. A. Prado --- Changes in v3: - Make loop in vimc_mbus_code_by_index() clearer by using break instead of if - Use VIMC_PIX_FMT_MAX_CODES define instead of hardcoded value for the size of code array in struct vimc_pix_map Changes in v2: - Fix vimc_mbus_code_by_index not checking code array bounds - Fix array formatting - Rename variables - Change code array size - Add comment about vimc_mbus_code_by_index return value drivers/media/test-drivers/vimc/vimc-common.c | 71 ++++++++++++------- drivers/media/test-drivers/vimc/vimc-common.h | 13 +++- drivers/media/test-drivers/vimc/vimc-scaler.c | 10 ++- drivers/media/test-drivers/vimc/vimc-sensor.c | 6 +- 4 files changed, 68 insertions(+), 32 deletions(-) diff --git a/drivers/media/test-drivers/vimc/vimc-common.c b/drivers/media/test-drivers/vimc/vimc-common.c index c95c17c048f2..e11107e4796c 100644 --- a/drivers/media/test-drivers/vimc/vimc-common.c +++ b/drivers/media/test-drivers/vimc/vimc-common.c @@ -19,19 +19,19 @@ static const struct vimc_pix_map vimc_pix_map_list[] = { /* RGB formats */ { - .code = MEDIA_BUS_FMT_BGR888_1X24, + .code = { MEDIA_BUS_FMT_BGR888_1X24 }, .pixelformat = V4L2_PIX_FMT_BGR24, .bpp = 3, .bayer = false, }, { - .code = MEDIA_BUS_FMT_RGB888_1X24, + .code = { MEDIA_BUS_FMT_RGB888_1X24 }, .pixelformat = V4L2_PIX_FMT_RGB24, .bpp = 3, .bayer = false, }, { - .code = MEDIA_BUS_FMT_ARGB8888_1X32, + .code = { MEDIA_BUS_FMT_ARGB8888_1X32 }, .pixelformat = V4L2_PIX_FMT_ARGB32, .bpp = 4, .bayer = false, @@ -39,49 +39,49 @@ static const struct vimc_pix_map vimc_pix_map_list[] = { /* Bayer formats */ { - .code = MEDIA_BUS_FMT_SBGGR8_1X8, + .code = { MEDIA_BUS_FMT_SBGGR8_1X8 }, .pixelformat = V4L2_PIX_FMT_SBGGR8, .bpp = 1, .bayer = true, }, { - .code = MEDIA_BUS_FMT_SGBRG8_1X8, + .code = { MEDIA_BUS_FMT_SGBRG8_1X8 }, .pixelformat = V4L2_PIX_FMT_SGBRG8, .bpp = 1, .bayer = true, }, { - .code = MEDIA_BUS_FMT_SGRBG8_1X8, + .code = { MEDIA_BUS_FMT_SGRBG8_1X8 }, .pixelformat = V4L2_PIX_FMT_SGRBG8, .bpp = 1, .bayer = true, }, { - .code = MEDIA_BUS_FMT_SRGGB8_1X8, + .code = { MEDIA_BUS_FMT_SRGGB8_1X8 }, .pixelformat = V4L2_PIX_FMT_SRGGB8, .bpp = 1, .bayer = true, }, { - .code = MEDIA_BUS_FMT_SBGGR10_1X10, + .code = { MEDIA_BUS_FMT_SBGGR10_1X10 }, .pixelformat = V4L2_PIX_FMT_SBGGR10, .bpp = 2, .bayer = true, }, { - .code = MEDIA_BUS_FMT_SGBRG10_1X10, + .code = { MEDIA_BUS_FMT_SGBRG10_1X10 }, .pixelformat = V4L2_PIX_FMT_SGBRG10, .bpp = 2, .bayer = true, }, { - .code = MEDIA_BUS_FMT_SGRBG10_1X10, + .code = { MEDIA_BUS_FMT_SGRBG10_1X10 }, .pixelformat = V4L2_PIX_FMT_SGRBG10, .bpp = 2, .bayer = true, }, { - .code = MEDIA_BUS_FMT_SRGGB10_1X10, + .code = { MEDIA_BUS_FMT_SRGGB10_1X10 }, .pixelformat = V4L2_PIX_FMT_SRGGB10, .bpp = 2, .bayer = true, @@ -89,25 +89,25 @@ static const struct vimc_pix_map vimc_pix_map_list[] = { /* 10bit raw bayer a-law compressed to 8 bits */ { - .code = MEDIA_BUS_FMT_SBGGR10_ALAW8_1X8, + .code = { MEDIA_BUS_FMT_SBGGR10_ALAW8_1X8 }, .pixelformat = V4L2_PIX_FMT_SBGGR10ALAW8, .bpp = 1, .bayer = true, }, { - .code = MEDIA_BUS_FMT_SGBRG10_ALAW8_1X8, + .code = { MEDIA_BUS_FMT_SGBRG10_ALAW8_1X8 }, .pixelformat = V4L2_PIX_FMT_SGBRG10ALAW8, .bpp = 1, .bayer = true, }, { - .code = MEDIA_BUS_FMT_SGRBG10_ALAW8_1X8, + .code = { MEDIA_BUS_FMT_SGRBG10_ALAW8_1X8 }, .pixelformat = V4L2_PIX_FMT_SGRBG10ALAW8, .bpp = 1, .bayer = true, }, { - .code = MEDIA_BUS_FMT_SRGGB10_ALAW8_1X8, + .code = { MEDIA_BUS_FMT_SRGGB10_ALAW8_1X8 }, .pixelformat = V4L2_PIX_FMT_SRGGB10ALAW8, .bpp = 1, .bayer = true, @@ -115,49 +115,49 @@ static const struct vimc_pix_map vimc_pix_map_list[] = { /* 10bit raw bayer DPCM compressed to 8 bits */ { - .code = MEDIA_BUS_FMT_SBGGR10_DPCM8_1X8, + .code = { MEDIA_BUS_FMT_SBGGR10_DPCM8_1X8 }, .pixelformat = V4L2_PIX_FMT_SBGGR10DPCM8, .bpp = 1, .bayer = true, }, { - .code = MEDIA_BUS_FMT_SGBRG10_DPCM8_1X8, + .code = { MEDIA_BUS_FMT_SGBRG10_DPCM8_1X8 }, .pixelformat = V4L2_PIX_FMT_SGBRG10DPCM8, .bpp = 1, .bayer = true, }, { - .code = MEDIA_BUS_FMT_SGRBG10_DPCM8_1X8, + .code = { MEDIA_BUS_FMT_SGRBG10_DPCM8_1X8 }, .pixelformat = V4L2_PIX_FMT_SGRBG10DPCM8, .bpp = 1, .bayer = true, }, { - .code = MEDIA_BUS_FMT_SRGGB10_DPCM8_1X8, + .code = { MEDIA_BUS_FMT_SRGGB10_DPCM8_1X8 }, .pixelformat = V4L2_PIX_FMT_SRGGB10DPCM8, .bpp = 1, .bayer = true, }, { - .code = MEDIA_BUS_FMT_SBGGR12_1X12, + .code = { MEDIA_BUS_FMT_SBGGR12_1X12 }, .pixelformat = V4L2_PIX_FMT_SBGGR12, .bpp = 2, .bayer = true, }, { - .code = MEDIA_BUS_FMT_SGBRG12_1X12, + .code = { MEDIA_BUS_FMT_SGBRG12_1X12 }, .pixelformat = V4L2_PIX_FMT_SGBRG12, .bpp = 2, .bayer = true, }, { - .code = MEDIA_BUS_FMT_SGRBG12_1X12, + .code = { MEDIA_BUS_FMT_SGRBG12_1X12 }, .pixelformat = V4L2_PIX_FMT_SGRBG12, .bpp = 2, .bayer = true, }, { - .code = MEDIA_BUS_FMT_SRGGB12_1X12, + .code = { MEDIA_BUS_FMT_SRGGB12_1X12 }, .pixelformat = V4L2_PIX_FMT_SRGGB12, .bpp = 2, .bayer = true, @@ -182,13 +182,32 @@ const struct vimc_pix_map *vimc_pix_map_by_index(unsigned int i) return &vimc_pix_map_list[i];
