media: cadence: cdns-csi2rx: Support multiple pixels per clock cycle

2025-08-25T13:40:42Z

The output pixel interface is a parallel bus (32 bits), which supports sending multiple pixels (1, 2 or 4) per clock cycle for smaller pixel widths like RAW8-RAW16. Dual-pixel and Quad-pixel modes can be a requirement if the export rate of the Cadence IP in Single-pixel mode maxes out before the maximum supported DPHY-RX frequency, which is the case with TI's integration of this IP [1]. So, we export a function that lets the downstream hardware block request a higher pixel-per-clock on a particular output pad. We check if we can support the requested pixels per clock given the known maximum for the currently configured format. If not, we set it to the highest feasible value and return this value to the caller.

Enable the csi2rx_err_irq interrupt to record any errors during streaming and also add support for VIDIOC_LOG_STATUS ioctl. This allows users to retrieve detailed error information during streaming, including FIFO overflow, packet errors, and ECC errors.

media: v4l: Convert the users of v4l2_get_link_freq to call it on a pad

2025-02-15T14:22:58Z

Call v4l2_get_link_freq() on a pad, instead of a control handler. This way we can soon convert v4l2_get_link_freq() to be callable only on a pad and remove the compatibility code.

media: Switch back to struct platform_driver::remove()

2024-10-12T14:28:25Z

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/media to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

media: cadence: csi2rx: configure DPHY before starting source stream

2024-04-22T09:41:04Z

When the source device is operating above 1.5 Gbps per lane, it needs to send the Skew Calibration Sequence before sending any HS data. If the DPHY is initialized after the source stream is started, then it might miss the sequence and not be able to receive data properly. Move the start of source subdev to the end of the sequence to make sure everything is ready to receive data before the source starts streaming.
