2022-06-20media: imx-jpeg: Don't fill the description field in struct v4l2_fmtdescMing Qian
The core will fill this in v4l_fill_fmtdesc(), ensuring consistent format description names. Signed-off-by: Ming Qian <ming.qian@nxp.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
2022-05-13media: imx-jpeg: Support dynamic resolution changeMing Qian
To support dynamic resolution change, driver should meet the following conditions: 1. the previous pictures are all decoded before source change event. 2. prevent decoding new resolution pictures with incorrect capture buffer, until user handle source change event and setup capture. 3. report correct fmt and resolution during source change.

2022-05-13media: imx-jpeg: Propagate the output frame size to the capture sideMing Qian
The GStreamer v4l2videodec only ever calls S_FMT on the output side and then expects G_FMT on the capture side to return a valid format.

2022-05-13media: imx-jpeg: Identify and handle precision correctlyMing Qian
The decoder will save the precision that was detected from jpeg header and use it later, when choosing the pixel format and also calculate bytesperline according to precision. The 12bit jpeg is not supported yet, but driver shouldn't led to serious problem if user enqueue a 12 bit jpeg. And the 12bit jpeg is supported by hardware, driver may support it later.

2022-04-24media: imx-jpeg: don't change byteused of queued bufferMing Qian
Don't change the output buffer's bytesused set by user. Drop allow_zero_bytesused, since it's deprecated. This should also guarantee it's the application's responsibility to set bytesused for the output buffer.

2022-04-24media: imx-jpeg: Correct the pixel format of rgbMing Qian
The hardware is capable of encoding/decoding RGB and ARGB formats in whatever order the color components are, but the resulting jpegs look good if we start with raw data in BGR/ABGR order, so we will further only support V4L2_PIX_FMT_BGR24 and V4L2_PIX_FMT_ABGR32.

2022-04-24media: v4l: ioctl: Set bus_info in v4l_querycap()Sakari Ailus
The bus_info field is set by most drivers based on the type of the device bus as well as the name of the device. Do this in v4l_querycap() so drivers don't need to. This keeps compatibility with non-default and silly bus_info.
