2024-06-28media: vivid: vidioc_g_edid: do not change the original input EDIDHans Verkuil
Returning an EDID for a connected output would modify the original input EDID with the physical address of the output. That causes problems, and it should just update the physical address of the output EDID. Update vivid_hdmi_edid to set the physical address to 0.0.0.0.

2024-06-27Revert "media: stm32: dcmipp: correct error handling in dcmipp_create_subdevs"Hans Verkuil
This reverts commit 77d32b7e2a7b2e5389b67363d25371b4b8cad140. This patch is obviously wrong (causes array accesses at index -1), and I caught that just too late.
2024-06-27media: imx-mipi-csis: Use v4l2_subdev_enable_streams()Laurent Pinchart
To support sources that implement the .enable_streams() and .disable_streams() operations, replace the manual calls to the subdev .s_stream() operation with the v4l2_subdev_enable_streams() and v4l2_subdev_disable_streams() helpers. The helpers fall back to .s_stream() if the source doesn't implement the new operations, so backward compatibility is preserved.

2024-06-26media: vimc: scaler: Use subdev active stateLaurent Pinchart
Store the active formats and crop rectangle in the subdevice active state. This simplifies implementation of the format and selection accessors, and allows using the v4l2_subdev_get_fmt() helper to implement the .get_fmt() operation. The active configuration that is used in the .process_frame() handler is still stored in the vimc_scaler_device structure. The driver could instead access the active state in the .process_frame() handler, but the required locking could interfere with the real time constraints of the frame processing. This data would be stored in registers in the .s_stream() handler for real hardware, storing it in dedicated storage thus mimics a real driver. To differentiate them from the rest of the device private data, move the corresponding fields to a sub-structure of vimc_scaler_device named hw.

The reason this always worked is that this function is called to write just 6 bytes (a MAC address) to the USB device, and so in practice there is only a single chunk written. If we ever would need to write more than one chunk, this function would fail since each chunk would read from or write to the same buf address. Rewrite the function to properly handle this.

2024-06-24media: dt-bindings: Add Imagination E5010 JPEG EncoderDevarsh Thakkar
Add dt-bindings for Imagination E5010 JPEG Encoder [1] which is implemented as stateful V4L2 M2M driver. The device supports baseline encoding with two different quantization tables and compression ratio as demanded. Minimum resolution supported is 64x64 and Maximum resolution supported is 8192x8192.

2024-06-21media: chips-media: wave5: support Wave515 decoderIvan Bornyakov
Add initial support for the Wave515 multi-decoder IP. For now it is only able to decode HEVC Main/Main10 profile videos into YUV420. This was tested on FPGA prototype, so wave5_dt_ids[] was not expanded. Users of the real hardware with Wave515 IP will have to * provide firmware specific to their SoC * add struct wave5_match_data like this: static const struct wave5_match_data platform_name_wave515_data = { .flags = WAVE5_IS_DEC, .fw_name = "cnm/wave515_platform_name_fw.bin", .sram_size = (71 * 1024), }; * add item to wave5_dt_ids[] like this: { .compatible = "vendor,soc-wave515", .data = &platform_name_wave515_data, }, * describe new compatible in Documentation/devicetree/bindings/media/cnm,wave521c.yaml Signed-off-by: Ivan Bornyakov <brnkv.i1@gmail.com> Signed-off-by: Sebastian Fricke <sebastian.fricke@collabora.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl>
2024-06-21media: chips-media: wave5: drop "sram-size" DT propertyIvan Bornyakov
Move the excessive "sram-size" device-tree property to the device match data. Also change the SRAM memory allocation strategy, instead of allocating exactly sram_size bytes, allocate all available SRAM memory up to sram_size. Add the placeholders wave5_vpu_dec_validate_sec_axi() and wave5_vpu_enc_validate_sec_axi() to validate that the allocated SRAM memory is sufficient to decode/encode bitstream with a given resolution.

Implement a separate setup routine for interrupts to reduce code duplication. Also enable interrupts based on vpu_attr->support_encoders and vpu_attr->support_decoders fields to facilitate support for other Wave5xx IPs, because not all of them are both encoders and decoders.
