Call mtk_jpeg_try_fmt_mplane() to replace the original computation of sizeimage and bytesperline, because that mtk_jpeg_try_fmt_mplane() already did it. Reviewed-by:

Jpeg doesn't support colorspace conversion, so it shouldn't accept any other colorspace in S_FMT. Change the colorspace of jpeg to the fixed value. Reviewed-by:

Delete the unused ctx parameter. Using mtk_jpeg_formats and num_formats parameters is more generic, because that jpeg enc will also use it. Delete the macro definition of MTK_JPEG_FMT_TYPE_OUTPUT and MTK_JPEG_FMT_TYPE_CAPTURE, because that MTK_JPEG_FMT_FLAG_DEC_OUTPUT and MTK_JPEG_FMT_FLAG_DEC_CAPTURE are enough. Reviewed-by:

The function of mtk_jpeg_adjust_fmt_mplane() equals mtk_jpeg_g_fmt_vid_mplane(), so use mtk_jpeg_g_fmt_vid_mplane() to replace it . Delete the unused ctx parameter. Using fourcc to distinguish between different formats is more generic, because that jpeg enc will also use it. Reviewed-by:

There is a delayed work scheduled before starting the hardware and canceled in the interrupt handler. If the delayed work is executed, it resets the hardware and reports the failure to V4L2, so that the execution can continue from next frames. Reviewed-by:

Add v4l2_m2m_suspend() function call in mtk_jpeg_suspend() to make sure that the current frame is processed completely before suspend. Add v4l2_m2m_resume() function call in mtk_jpeg_resume() to unblock the driver from scheduling next frame. Reviewed-by:

Add two functions that can be used to stop new jobs from being queued / continue running queued job. This can be used while a driver using m2m helper is going to suspend / wake up from resume, and can ensure that there's no job running in suspend process. Signed-off-by:

The driver can be instantiated multiple times, e.g. for a decoder and an encoder. Moreover, other drivers could coexist on the same system. This makes the static video node number assignment pointless, so switch to automatic assignment instead. Reviewed-by:

Settle time determines the number of cil clock cyles to wait after LP00 when moving from LP to HS. This patch computes T-CLK-SETTLE and T-HS-SETTLE times based on cil clock rate and pixel rate from the sensor and programs them during streaming. T-CLK-SETTLE time is the interval during which receiver will ignore any HS transitions on clock lane starting from the beginning of T-CLK-PREPARE. T-HS-SETTLE time is the interval during which recevier will ignore any HS transitions on data lane starting from the beginning of T-HS-PREPARE. Signed-off-by:

CSI MIPI pads need to be enabled and calibrated for capturing from the external sensor or transmitter. MIPI CAL unit calibrates MIPI pads pull-up, pull-down and termination impedances. Calibration is done by co-work of MIPI BIAS pad and MIPI CAL control unit. Triggering calibration start can happen any time after MIPI pads are enabled but calibration results will be latched and applied to MIPI pads by MIPI CAL unit only when the link is in LP11 state and then calibration status register gets updated. This patch enables CSI MIPI pads and calibrates them during streaming. Tegra CSI receiver is able to catch the very first clock transition. So, CSI receiver is always enabled prior to sensor streaming and trigger of calibration start is done during CSI subdev streaming and status of calibration is verified after sensor stream on.

With the split of MIPI calibration into tegra_mipi_calibrate() and tegra_mipi_wait(), MIPI clock is not kept enabled and mutex is not locked till the calibration is done. So, this patch keeps MIPI clock enabled and mutex locked after triggering start of calibration till its done. To let calibration process go through its finite sequence codes before calibration logic waiting for pads idle state added wait time of 75usec to make sure it sees idle state to apply the results. This patch renames tegra_mipi_calibrate() as tegra_mipi_start_calibration() and tegra_mipi_wait() as tegra_mipi_finish_calibration() to be inline with their usage. Reviewed-by:

This patch adds selection v4l2 ioctl operations to allow configuring a selection rectangle in the sensor through the Tegra video device node. Some sensor drivers supporting crop uses try_crop rectangle from v4l2_subdev_pad_config during try format for computing binning. So with selection ops support, this patch also updates try format to use try crop rectangle either from subdev frame size enumeration or from subdev crop boundary. Signed-off-by:

This patch adds support to capture from the external sensor based on device graph in the device tree. Driver walks through the device graph to create media links between the entities and registers and unregisters video devices when the corresponding sub-devices are bound and unbound. Channel formats are enumerated based on available formats from the sensor and the corresponding matched formats from the Tegra supported video formats list. Each Tegra CSI instance can be configured as 4-lane or 2-lane based on supported lane configuration from the sensor through the device tree. Currently this driver supports V4L2 video node centric only. [hverkuil: changed video_unregister_device to vb2_video_unregister_device] Signed-off-by:

Tegra VI supported video formats are more for non TPG and there can be multiple pixel formats for the same media bus format. This patch updates the helper function for format lookup based on mbus code from pre-defined Tegra supported format list to look from the specified list index offset. Offset based look up is used with sensor device graph (non TPG) where format enumeration can list all supported formats for the specific sensor mbus codes. Signed-off-by:

Tegra internal TPG mode is only for Tegra vi and csi testing without a real sensor and driver should default support real sensor. So, This patch adds CONFIG_VIDEO_TEGRA_TPG and enables Tegra internal TPG mode only when this config is selected. Signed-off-by:

Pixel format width is mistakenly aligned to surface align bytes and altering width to aligned value may force sensor mode change other than the requested one and also cause mismatch in width programmed between sensor and vi which can lead to capture errors. This patch removes width alignment and clamps width as per Tegra minimum and maximum limits. Signed-off-by:

This is only needed for drivers that do not use vb2_fop_release(). Note that vb2_queue_release() is *not* the counterpart of vb2_queue_init() as some drivers here seem to think. Also use vb2_video_unregister_device() to automatically stop streaming at unregister time for those drivers that set vdev->queue. Signed-off-by:

If a driver calls (_)vb2_fop_release(), then such a driver should also call vb2_video_unregister_device() instead of video_unregister_device(). This helper will call vb2_queue_release() if a filehandle is marked as owner of the queue. This ensures that at unregister time any streaming is cancelled and all buffers are returned to userspace. This is very useful for complex drivers since this stops all streaming in all subdevs in the pipeline controlled by this video device. Otherwise this would be delayed until the owner filehandle is closed, which can be quite some time later. Bonus points for ordering the includes :-) Signed-off-by:
