The V4L2_PIX_FMT_S5C_YUYV_JPG image formats consists of 2 planes, the first containing interleaved JPEG/YUYV data and the second containing meta data describing the interleaving method. The image data is transferred with MIPI-CSI "User Defined Byte-Based Data 1" type and is captured to memory by FIMC DMA engine. The meta data is transferred using MIPI-CSI2 "Embedded 8-bit non Image Data" and it is captured in the MIPI-CSI slave device and copied to the bridge provided buffer. To make sure the size of allocated buffers is correct for the subdevs configuration when VIDIOC_STREAMON ioctl is invoked, an additional check is added at the video pipeline validation function. Flag FMT_FLAGS_COMPRESSED indicates the buffer size must be retrieved from a sensor subdev. Signed-off-by:

MIPI-CSI has internal memory mapped buffers for the frame embedded (non-image) data. There are two buffers, for even and odd frames which need to be saved after an interrupt is raised. The packet data buffers size is 4 KiB and there is no status register in the hardware where the actual non-image data size can be read from. Hence the driver copies whole packet data buffer into a buffer provided by the FIMC driver. This will form a separate plane in the user buffer. When FIMC DMA engine is stopped by the driver due the to user space not keeping up with buffer de-queuing the MIPI-CSIS will still run, however it must discard data which is not captured by FIMC. Which frames are actually capture by MIPI-CSIS is determined by means of the s_tx_buffer subdev callback. When it is not called after a single embedded data frame has been captured and copied and before next embedded data frame interrupt occurrs, subsequent embedded data frames will be dropped.

This patch adds definition of the Samsung S5C73M3 camera specific image format. V4L2_PIX_FMT_S5C_UYVY_JPG is a two-planar format, the first plane contains interleaved UYVY and JPEG data followed by meta-data. The second plane contains additional meta-data needed for extracting JPEG and UYVY data stream from the first plane. Signed-off-by:

This patch adds media bus pixel code for the interleaved JPEG/UYVY image format used by S5C73MX Samsung cameras. This interleaved image data is transferred on MIPI-CSI2 bus as User Defined Byte-based Data. It also defines an experimental vendor and device specific media bus formats section and adds related DocBook documentation. Signed-off-by:

Add subdev callbacks for setting up parameters of the frame on media bus that are not exposed to user space directly. This is just an initial, mostly stub implementation. struct v4l2_mbus_frame_desc is intended to be extended with sub-structures specific to a particular hardware media bus. For now these new callbacks are used only to query or specify maximum size of a compressed or hybrid (container) media bus frame in octets. Signed-off-by:

The s_rx_buffer callback allows the host to set buffer for a data being received by the subdev, e.g. non-image frame (meta) data. This callback can be implemented by subdevice like a MIPI CSI2 receiver, allowing the host driver to gather additional data into frame buffer passed to user space. Signed-off-by:

As spotted by Dan Carpenter <dan.carpenter@oracle.com> (thanks!), we have improperly used an unsigned variable in a calculation that may result in a negative number. This may cause an unintended underflow if the interface frequency of the tuner is > approx. 40MHz. This patch should resolve the issue, following an approach similar to what is used in af9013.c.

As em28xx-dvb will always be initialized asynchronously, there's no need anymore for a separate thread to load the DRX-K firmware. Fixes a known regression with kernel 3.6 with tda18271 driver and asynchronous DRX-K firmware load. Antti tested it with the following hardware: Hauppauge WinTV HVR 930C MaxMedia UB425-TC PCTV QuatroStick nano (520e) Tested-by: -

Due to udev-182, the firmware load was changed to be async, as otherwise udev would give up of loading a firmware. Add an option to return to the previous behaviour, async firmware loads cause failures with the tda18271 driver.

em28xx-dvb, em28xx-alsa and em28xx-ir are typically initialized asyncrhronously. The exception for it is when those modules are loaded before em28xx (or before an em28xx card insertion) or when they're built in. Make the extentions to always load asynchronously. That allows having all DVB firmwares loaded synchronously with udev-182.

if the configuration option 'delay_cal' is set, delay both IR & RF calibration until init() is called. both module option 'cal' or configuration option 'rf_cal_on_startup' will override this delay. it makes no sense to mix 'delay_cal' with 'rf_cal_on_startup' as these options conflict with each other.

The mixer video node supports only multi-planar API so the driver should not be setting V4L2_CAP_VIDEO_OUTPUT flags. Fix this and also switch to device_caps. Additionally fix the VIDIOC_ENUM_FMT ioctl handler which now works for V4L2_BUF_TYPE_CAPTURE, rather than expected V4L2_BUF_TYPE_CAPTURE_MPLANE. Signed-off-by:

Make sure __s5k6aa_get_crop_rect() always returns valid pointer, as it is assumed at the callers. crop->which is already validated when subdev set_crop and get_crop callbacks are called from within the v4l2-core. If it ever happens the crop operations are called directly for some reason in kernel space, with incorrect crop->which argument, just log it with WARN and return reference to the TRY crop.
