Add debug print statements to print the content of P & B reference lists, to verify that the ordering of the generated reference lists is correct. This is especially important for the field decoding mode, where sorting is more complex. Signed-off-by:

This information, also called picture structure, is required in field decoding mode to construct reference lists. Signed-off-by:

This is to accommodate support for field decoding, which splits the top and the bottom references into the reference list. Signed-off-by:

In preparation for adding field decoding support, convert the byte arrays for reflist into array of struct v4l2_h264_reference. That struct will allow us to mark which field of the reference picture is being referenced. [hverkuil: top_field_order_cnt -> pic_order_count] Signed-off-by:

V4L2 controls initialisation takes up a sizeable portion of the driver's .probe() function. To keep things neat, move it to a dedicated function. Signed-off-by:

The OVTI7251 sensor can be found on x86 laptops with an IPU3, and so needs to be supported by the cio2-bridge. Add it to the table of supported sensors. Signed-off-by:

.probe() is quite busy for this driver; make it cleaner by moving the chip verification to a dedicated function. Signed-off-by:

The OV7251 sensor is used as the IR camera sensor on the Microsoft Surface line of tablets; this provides a 19.2MHz external clock, and the Windows driver for this sensor configures a 319.2MHz link freq to the CSI-2 receiver. Add the ability to support those rate to the driver by defining a new set of PLL configs. Signed-off-by:

Daniel Scally authored
Rather than having the pll settings hidden inside mode blobs, define them in structs and use a dedicated function to set them. This makes it simpler to extend the driver to support other frequencies for both the external clock and desired link frequency. Signed-off-by:
-
Daniel Scally authored
Each of the defined modes in the ov7251 driver uses the same link frequency and pixel rate; just drop those members of the modes and set the controls to read only during initialisation. Add a new table defining the supported pixel rates to substitue for the values hardcoded in the modes. Signed-off-by:

Daniel Scally authored
Move the endpoint checking from .probe() to a dedicated function, and additionally check that the firmware provided link frequencies are a match for those supported by the driver. Store the index to the matching link frequency so it can be easily identified later. Signed-off-by:

We have platforms where a camera sensor transmits Y10 data to the CIO2 device - add support for that (packed) format to the ipu3-cio2 driver. Signed-off-by:
-
Daniel Scally authored
Some platforms with an Intel IPU3 have an IR sensor producing 10 bit greyscale format data that is transmitted over a CSI-2 bus to a CIO2 device - this packs the data into 32 bytes per 25 pixels. Add an entry to the uAPI header defining that format. Signed-off-by:

MWB gain register are used to set gain for each mwb channel mannually. However, it will involve some artifacts if gain cannot be applied to each channel synchronously. Enable global gain control to set digital global gain instead of setting AWB gain separately to fix this issue. Signed-off-by:

ADV7180 has a built-in mechanism to generate some video patterns, which is very useful for debug/bring-up activities. Add support for it. The test_pattern parameter can be one of the following values: 0: "Single color" 1: "Color bars" 2: "Luma ramp" 3: "Boundary box" 4: "Disable" Tested on a imx6q board with an ADV7280. Signed-off-by:

Use get_frame_desc() to get the frame desc from the connected source, and use the provided virtual channel and datatype instead of hardcoded ones. get_frame_desc() can contain multiple streams, but as we don't support multiple streams yet, we will just always use the first stream. If the source doesn't support get_frame_desc(), fall back to the previous method of always capturing virtual channel 0 and any datatype. Signed-off-by:

There is firmware out there that uses "dongwoon,dw9807" compatible string that never made it to upstream as-is. Add it to the driver to make it load on such systems. The chip also has an EEPROM part which is AT24 compatible (for reading purposes) on a separate I²C address. Adding possible support for this in the future is not affected by this change.
