Raw camera sensors connected to parallel or CSI-2 busses need to implement V4L2_CID_LINK_FREQ control so receiver drivers can configure the hardware accordingly. Document this. Also say V4L2_CID_PIXEL_RATE is recommended for such hardware. Signed-off-by:

Compare the received size of the payload size, not the allocated size of the buffer that is page aligned. This way also images that aren't aligned to page size are not warned about. Also wrap a line over 80 characters. Suggested-by:

Add support to read the bus-type for V4L2_MBUS_BT656 and enable BT.656 mode in the sensor if needed. For backward compatibility with older DTS where the bus-type property was not mandatory, assume V4L2_MBUS_PARALLEL as it was the only supported bus at the time. v4l2_fwnode_endpoint_alloc_parse() will not fail if 'bus-type' is not specified.

Earlier it was expected that there would be more variable size endpoint properties and that most if not all drivers would need them. For that reason it was expected also that v4l2_fwnode_endpoint_parse would no longer be needed. What actually happened that not all drivers require "link-frequencies", the only variable size media endpoint property without a small upper limit. Therefore drivers that do not need that information are fine using v4l2_fwnode_endpoint_parse. So don't tell drivers to use v4l2_fwnode_endpoint_alloc_parse in all cases. Signed-off-by:

Document that the caller of v4l2_fwnode_endpoint_parse() must init the fields of struct v4l2_fwnode_endpoint (vep argument) fields. It used to be that the fields were zeroed by v4l2_fwnode_endpoint_parse when bus type was set to V4L2_MBUS_UNKNOWN but with recent changes (Fixes: line below) that no longer makes sense.

The v4l2_fwnode_parse_endpoint() function can make use of defaults in multiple bus types. To use this feature, all callers must zero the rest of the fields of this struct, too. All other drivers appear to do that already apart from this one. Signed-off-by:

Convert to YAML and add generic IP core compatibles "cnm,codadx6", "cnm,codahx4", "cnm,coda7541", and "cnm,coda960" in addition to the SoC specific compatibles. The new generic compatibles are already used in the SoC device trees and replace the free form comments. For example: - compatible : should be "fsl,<chip>-src" for i.MX SoCs: (a) "fsl,imx27-vpu" for CodaDx6 present in i.MX27 turns into: properties: compatible: oneOf: - items: - const: fsl,imx27-vpu - const: cnm,codadx6 This allows to properly specify the secondary JPEG unit interrupt that is only present on cnm,coda960. Also add the missing "fsl,imx6dl-vpu", "cnm,coda960" compatible. The AXI bus connection to the internal SRAM is different between i.MX6Q and i.MX6DL, which requires the driver to load a different firmware depending on the SoC. Further, specify the power-domain property for i.MX6 and change the clock order from "ahb", "per" to "per", "ahb". This order is currently used in all SoC device trees.

Document endpoint properties for the parallel bus type and add them to the example. Specify a few constraints: - If the bus type is BT.656 no hsync or vsync polarities can be specified. - If the bus width is 10 bits, not data-shift can be applied. Reviewed-by:

In order to establish required properties based on the selected bus type, make the 'bus-type' property mandatory. As this change documents an endpoint property, also document the 'remote-endpoint' one now that the 'endpoint' schema has been expanded. Binary compatibility with existing DTB is kept as the driver does not enforce the property to be present, and shall fall-back to default parallel bus configuration, which was the only supported bus type, if the property is not specified.
