2025-05-02media: rcar-isp: Rename base register variableNiklas Söderlund
Prepare for extending the driver to in addition to supporting the channel selector (CS) also support the core ISP. The two different functions have different base addresses so the driver needs to distinguish between them. Prepare for this by marking existing base address variable and read/write functions to make it clear they operate on the CS portion of the driver. There is no functional change.

Fix the following to get RAW10 formats working: In rvin_formats, the bpp is set to 4 for RAW10. As VIN unpacks RAW10 to 16-bit containers, the bpp should be 2. Don't set VNDMR_YC_THR to the VNDMR register. The YC_THR is "YC Data Through Mode", used for YUV formats and should not be set for RAW10.

2025-04-25media: rcar-vin: Simplify the shutdown processNiklas Söderlund
When shutting down capture extra care was needed to try and complete a buffer that was involved in the emulated support for SEQ_{TB,BT}. This was needed as a buffer might be queued once to the driver, but two times to the hardware using different offsets. As support for SEQ_{TB,BT} is now removed this shutdown process can be greatly simplified. And in addition the state keeping of the VIN device can be reduced to a single boolean value instead of keeping track of this SEQ_{TB,BT} stopping dance.

2025-04-25media: rcar-vin: Remove superfluous starting stateNiklas Söderlund
The STARTING state is superfluous and can be replaced with a check of the sequence counter. The design idea is that the first buffer returned from the driver have to come from the first hardware buffer slot. Failing this the first 3 buffers queued to the device can be returned out-of-order. But it's much clearer to check the sequence counter to only return the first buffer if it comes from hardware slot 0 then it is to carry around an extra state just for this. Remove the unneeded state and replace it with a simpler check.

2025-04-25media: rcar-vin: Remove superfluous suspended stateNiklas Söderlund
The VIN state of suspended is superfluous. The logic was that when the device were suspended and in a RUNNING state the state was set to SUSPENDED. And when resuming it checked if the state is SUSPENDED and if so started the device and changed it to RUNNING. This can be avoided by simply checking if the device is in a RUNNING state at both suspend and resume callbacks. Remove the unneeded complexity.

2025-04-25media: rcar-vin: Remove emulated SEQ_{TB,BT}Niklas Söderlund
When the driver was converted from soc_camera software support for V4L2_FIELD_SEQ_TB and V4L2_FIELD_SEQ_BT were added. This was done by capturing twice to the same VB2 buffer, but at different offsets. This turned out to be a bad idea and it never really worked properly in all situations. As the hardware can't support this mode natively remove trying to emulate it in software. It's still possible to capture TOP or BOTTOM fields separately or both ALTERNATING. If user-space wants the same fields in the same buffer the same hack to capture twice to the same buffer can be done. Removing this error prone emulated support pave ways in future work to simplify the internal buffer handling and making it less fragile, while enabling adding support for other features the hardware actually supports.

Later versions of the V4H datasheet adds documentation for the line order register needed to support all possible configurations. Extend the driver to take the line order for each data line into account when configuring the device. Unfortunately not all registers initially thought to be involved in line order configuration where directly related. One magic value is still in the driver and left as-is, but it is not related to line order as that procedure have now been documented.

2024-10-28media: platform: drop vb2_ops_wait_prepare/finishHans Verkuil
Since commit 88785982a19d ("media: vb2: use lock if wait_prepare/finish are NULL") it is no longer needed to set the wait_prepare/finish vb2_ops callbacks as long as the lock field in vb2_queue is set. Since the vb2_ops_wait_prepare/finish callbacks already rely on that field, we can safely drop these callbacks. This simplifies the code and this is a step towards the goal of deleting these callbacks.

2024-10-22media: renesas: rzg2l-cru: Add 'yuv' flag to IP format structureLad Prabhakar
Add a 'yuv' flag to the `rzg2l_cru_ip_format` structure to indicate whether a given format is YUV-based and update the `rzg2l_cru_ip_formats` array with this flag appropriately. This change enables a more efficient way to check if the input and output formats use the same colorspace. With this change, we can eliminate the use of `v4l2_format_info()` in `rzg2l_cru_initialize_image_conv()` as the necessary details for the source and destination formats are already available through the `yuv` flag.
