Allow sequential->interlaced interweaving but with top/bottom lines swapped to the output buffer. This can be accomplished by adding one line length to IDMAC output channel address, with a negative line length for the interlace offset. This is to allow the seq-bt -> interlaced-bt transformation, where bottom lines are still dominant (older in time) but with top lines first in the interweaved output buffer. With this support, the CSI can now allow seq-bt at its source pads, e.g. the following transformations are allowed in CSI from sink to source: seq-tb -> seq-bt seq-bt -> seq-bt alternate -> seq-bt Suggested-by:

If caller passes un-initialized field type V4L2_FIELD_ANY to CSI sink pad, the reset CSI crop window would not be correct, because the crop window depends on a valid input field type. To fix move the reset of crop and compose windows to after the call to imx_media_fill_default_mbus_fields(). Signed-off-by:

prepare_vdi_in_buffers() was setting up the dma pointers as if the VDIC is always programmed to receive the fields in bottom-top order, i.e. as if ipu_vdi_set_field_order() only programs BT order in the VDIC. But that's not true, ipu_vdi_set_field_order() is working correctly. So fix prepare_vdi_in_buffers() to give the VDIC the fields in whatever order they were received by the video source, and rely on the VDIC to sort out which is top and which is bottom. Signed-off-by:

If IDMAC interweaving is enabled in a write channel, the channel must write the odd chroma rows for 4:2:0 formats. Skipping writing the odd chroma rows produces corrupted captured 4:2:0 images when interweave is enabled. Reported-by:

If the incoming sink field type is alternate, the reset crop height and crop height bounds must be set to twice the incoming height, because in alternate field mode, upstream will report only the lines for a single field, and the CSI captures the whole frame. Signed-off-by:

IDMAC interlaced scan, a.k.a. interweave, should be enabled in the IDMAC output channels only if the IDMAC output pad field type is 'seq-bt' or 'seq-tb', and field type at the capture interface is 'interlaced*'. V4L2_FIELD_HAS_BOTH() macro should not be used on the input to determine enabling interlaced/interweave scan. That macro includes the 'interlaced' field types, and in those cases the data is already interweaved with top/bottom field lines. The CSI will capture whole frames when the source specifies alternate field mode. So the CSI also enables interweave for alternate input field type and the field type at capture interface is interlaced. Fix the logic for setting field type in try_fmt in CSI entity. The behavior should be: - No restrictions on field type at sink pad. - At the output pads, allow sequential fields in TB order, if the sink pad field type is sequential or alternate. Otherwise passthrough the field type from sink to source pad. Move this logic to new function csi_try_field(). These changes result in the following allowed field transformations from CSI sink -> source pads (all other field types at sink are passed through to source): seq-tb -> seq-tb seq-bt -> seq-tb alternate -> seq-tb In a future patch, the CSI sink -> source will allow: seq-tb -> seq-bt seq-bt -> seq-bt alternate -> seq-bt This will require supporting interweave with top/bottom line swapping. Until then seq-bt is not allowed at the CSI source pad because there is no way to swap top/bottom lines when interweaving to INTERLACED_BT -- note that despite the name, INTERLACED_BT is top-bottom order in memory. The BT in this case refers to field dominance: the bottom lines are older in time than the top lines. The capture interface device allows selecting IDMAC interweave by choosing INTERLACED_TB if the CSI/PRPENCVF source pad is seq-tb and INTERLACED_BT if the source pad is seq-bt (for future support of seq-bt).

To support interlaced scan with planar formats, cpmem SLUV must be programmed with the correct chroma line stride. For full and partial planar 4:2:2 (YUV422P, NV16), chroma line stride must be doubled. For full and partial planar 4:2:0 (YUV420, YVU420, NV12), chroma line stride must _not_ be doubled, since a single chroma line is shared by two luma lines. Signed-off-by:

The function ipu_csi_init_interface() was inverting the F-bit for NTSC case, in the CCIR_CODE_1/2 registers. The result being that for NTSC bottom-top field order, the CSI would swap fields and capture in top-bottom order. Instead, base field swap on the field order of the input to the CSI, and the field order of the requested output. If the input/output fields are sequential but different, swap fields, otherwise do not swap. This requires passing both the input and output mbus frame formats to ipu_csi_init_interface(). Move this code to a new private function ipu_csi_set_bt_interlaced_codes() that programs the CCIR_CODE_1/2 registers for interlaced BT.656 (and possibly interlaced BT.1120 in the future). When detecting input video standard from the input frame width/height, make sure to double height if input field type is alternate, since in that case input height only includes lines for one field.

Adds two helper macros: V4L2_FIELD_IS_SEQUENTIAL: returns true if the given field type is 'sequential', that is a full frame is transmitted, or exists in memory, as all top field lines followed by all bottom field lines, or vice-versa. V4L2_FIELD_IS_INTERLACED: returns true if the given field type is 'interlaced', that is a full frame is transmitted, or exists in memory, as top field lines interlaced with bottom field lines.

There is a block of code in rvin_group_link_notify() that prevents enabling a link to a VIN node if any entity in the media graph is in use. This prevents enabling a VIN link even if there is an in-use entity somewhere in the graph that is independent of the link's pipeline. For example, the code block will prevent enabling a link from the first rcar-csi2 receiver to a VIN node even if there is an enabled link somewhere far upstream on the second independent rcar-csi2 receiver pipeline. If this code block is meant to prevent modifying a link if any entity in the graph is actively involved in streaming (because modifying the CHSEL register fields can disrupt any/all running streams), then the entities stream counts should be checked rather than the use counts. (There is already such a check in __media_entity_setup_link() that verifies the stream_count of the link's source and sink entities are both zero, but that is insufficient, since there should be no running streams in the entire graph). Modify the code block to check the entity stream_count instead of the use_count (and elaborate on the comment). VIN node links can now be enabled even if there are other independent in-use entities that are not streaming. Fixes: c0cc5aef ("media: rcar-vin: add link notify for Gen3") Signed-off-by:
