Hello， When I was adapting my yuv sensor, I encountered a problem. My sensor was output by YUYV82X8, but the data I got after configuring the device tree as follows is in UYVY format. What is the problem?

hello Towe_Roll,

please refer to VI-5 formats.
you may try removing the 1st TEGRA_VIDEO_FORMAT since these two using the same fourcc (i.e. YUYV)
for instance,
$public_sources/kernel_src/kernel/nvidia/drivers/media/platform/tegra/camera/vi/vi5_formats.h

static const struct tegra_video_format vi5_video_formats[] = {
...
         /* YUV422 */
         TEGRA_VIDEO_FORMAT(YUV422, 16, YUYV8_1X16, 2, 1, T_Y8_U8__Y8_V8,
                                 YUV422_8, YUYV, "YUV 4:2:2"),
         TEGRA_VIDEO_FORMAT(YUV422, 16, YUYV8_2X8, 2, 1, T_Y8_U8__Y8_V8,
                                 YUV422_8, YUYV, "YUV 4:2:2 YUYV"),

please also revise camera_common_color_fmts[] within $public_sources/kernel_src/kernel/nvidia/drivers/media/platform/tegra/camera/camera_common.c
