2025-07-08media: cec: core: add rx-no-low-drive settingHans Verkuil
If rx-no-low-drive is set, then the CEC pin framework will disable the detection of situations where a Low Drive has to be generated. So if this is set, then we will never generate Low Drives. This helps testing whether other CEC devices generate Low Drive pulses by ensuring it is not us that is generating them.

2025-07-08media: cec: core: add glitch error injectionHans Verkuil
This adds support for inserting 'glitches' after a falling and/or rising edge. This tests what happens when there are little voltage spikes after falling or rising edges, which can be caused due to noise or reflections on the CEC line. A proper CEC implementation will deglitch this, but a poor implementation can create a Low Drive pulse in response, effectively making CEC unusable.

2025-07-08media: i2c: adv7604/tc358743/tda1997x: HPD low for HZ / 7Hans Verkuil
When the EDID is updated, the hotplug detect signal must remain low for 100 ms minimum. Currently these three drivers use that exact minimum, but some HDMI transmitters need the HPD to be low for a bit longer before they detect that they need to read the EDID again. Experience shows that HZ / 7 (= 143 ms) is a good value. So change HZ / 10 to HZ / 7. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

2025-07-03media: staging/ipu7: add IPU7 input system device driverBingbu Cao
The main input system driver mainly cover the basic hardware setup, v4l2 devices registration, firmware stream interfaces and interrupt handling. Input system CSI2 receiver is exposed as a v4l2 sub-device. Each CSI2 sub-device represent one single CSI2 hardware port which be linked with external sub-device such camera sensor by linked with ISYS CSI2's sink pad. The CSI2 source pad is linked to the sink pad of video capture device. Register V4L2 video device and setup the VB2 queues to support video capture. Video streaming callback will trigger the input system driver to construct a input system stream configuration for firmware based on data type and stream ID and then queue buffers to firmware to do capture. IPU7 CSI-2 D-PHY hardware is a Synopsys DWC MIPI CSI2 Rx IP, the driver program the DPHY to receive MIPI data from camera sensors.

2025-07-03media: staging/ipu7: add firmware parse, syscom interface and bootBingbu Cao
IPU7 irmware is generated and released as signed Code Partition Directory (CPD) format file which is aligned with the SPI flash code partition definition. The driver parses the CPD based on the layout. Syscom is an inter-process(or) communication mechanism between an IPU and host. Syscom uses message queues for message exchange between IPU and host. Each message queue has its consumer and producer, host queue messages to firmware as the producer and then firmware to dequeue the messages as consumer and vice versa. IPU and host use shared registers or memory to reside the read and write indices which are updated by consumer and producer. IPU7 firmware defined its boot sequence, driver setup the boot configuration and program the boot parameters to start and run the firmware.

2025-07-03media: iris: Add codec specific check for VP9 decoder drain handlingDikshita Agarwal
Add a codec specific for the VP9 decoder to ensure that a non-null buffer is sent to the firmware during drain. The firmware enforces a check for VP9 decoder that the number of buffers queued and dequeued on the output plane should match. When a null buffer is sent, the firmware does not return a response for it, leading to a count mismatch and an assertion failure from the firmware.

Firmware sends capture buffers with 0 filled length which are not to be displayed and should be dropped by client. To achieve the same, add V4L2_BUF_FLAG_ERROR to such buffers by making sure: - These 0 length buffers are not returned as result of flush. - Its not a buffer with LAST flag enabled which will also have 0 filled length.

2025-07-03media: iris: Fix buffer preparation failure during resolution changeDikshita Agarwal
When the resolution changes, the driver internally updates the width and height, but the client continue to queue buffers with the older resolution until the last flag is received. This results in a mismatch when the buffers are prepared, causing failure due to outdated size. Introduce a check to prevent size validation during buffer preparation if a resolution reconfiguration is in progress, to handle this.

2025-07-03media: iris: Track flush responses to prevent premature completionDikshita Agarwal
Currently, two types of flush commands are queued to the firmware, the first flush queued as part of sequence change, does not wait for a response, while the second flush queued as part of stop, expects a completion response before proceeding further. Due to timing issue, the flush response corresponding to the first command could arrive after the second flush is issued. This casuses the driver to incorrectly assume that the second flush has completed, leading to the premature signaling of flush_completion. To address this, introduce a counter to track the number of pending flush responses and signal flush completion only when all expected responses are received.

The current check only considers the core error state before allowing writes to the HFI queues. However, the core can also transition to the deinit state due to a system error triggered by the response thread. In such cases, writing to the HFI queues should not be allowed. Fix this by adding a check for the core deinit state, ensuring that writes are rejected when core is not in a valid state.

During reconfig, the firmware sends the resolution aligned to 8 bytes. If the driver sends the same resolution back to the firmware the resolution will be aligned to 16 bytes not 8.
