Commit f1a81afc ("[media] m2m: fix bad unlock balance") removed the last use of v4l2_m2m_ops.lock and v4l2_m2m_ops.unlock hooks. They are not actually used anymore. Remove them. Signed-off-by:

As per the documentation, job_abort is not required to wait until the current job finishes. It is redundant to do so, as the core will perform the wait operation. Remove the wait infrastructure completely. Signed-off-by:

Currently, rga_buf_start_streaming() is expecting pm_runtime_get_sync to return zero on success, which is wrong. As per the documentation, pm_runtime_get_sync increments the device's usage counter and return its result. This means it will typically return a positive integer on success and a negative error code. Therefore, rockchip-rga driver is currently unusable failing to start_streaming in most cases. Fix it and while here, cleanup the buffer return-to-core logic.

When checking a format for validity, the resolution is reset to 1280x720 whenever the pixel format is not supported. This behavior can mislead user-space into believing that this is the only resolution supported, and looks strange considering that if we try/set the same format with just the pixel format changed to a valid one, the call will this time succeed without altering the resolution. Resolution is managed independently of the pixel format, so remove this reset. Signed-off-by:

The check for a zero retval is redundant as all paths that lead to this point have set retval to an error return value that is non-zero. Remove the redundant check. Detected by CoverityScan, CID#102589 ("Logically dead code") Signed-off-by:Colin Ian King <colin.king@canonical.com> Signed-off-by:

If there is a schedulable job, v4l2_m2m_try_schedule() calls v4l2_m2m_try_run(). This makes the unconditional v4l2_m2m_try_run() called by v4l2_m2m_job_finish superfluous. Remove it. Fixes: 7f98639d ("V4L/DVB: add memory-to-memory device helper framework for videobuf") Signed-off-by:

Use the new renesas-ceu camera driver in ap325rxa board file instead of the soc_camera based sh_mobile_ceu_camera driver. Get rid of soc_camera specific components, and register CEU0 with a single video sensor (ov7725). Memory for the CEU video buffers is now reserved with membocks APIs and need to be declared as dma_coherent during machine initialization to remove that architecture specific part from CEU driver. The ap325rxa board file registers another camera (ncm03j) for which I found no driver in mainline kernel version, and that was configured/probed by sending i2c messages (of 'magic blobs) from the board file itself. I removed the sensor registration from this new version as it used soc_camera components that will be later removed. While at there update license to SPDX header and sort headers alphabetically. Compile tested only. Signed-off-by:

No need to udapte the clock source names, as commit c2f9b05f ("media: arch: sh: ecovec: Use new renesas-ceu camera driver") already updated it to the new ceu driver name for all SH7724 boards (possibly breaking ms7724se before this commit).

Remove soc_camera framework dependencies from rj54n1 sensor driver. - Handle clock - Handle GPIOs (named 'powerup' and 'enable') - Register the async subdevice - Remove g/s_mbus_config as they're deprecated. - Adjust build system - List the driver as maintained for 'Odd Fixes' as I don't have HW to test. This commits does not remove the original soc_camera based driver. Compiled tested only. Signed-off-by:

When starting the VIN capture procedure we are not guaranteed that the first buffer written to is VnMB1 to which we assigned the first buffer queued. This is problematic for two reasons. Buffers might not be dequeued in the same order they where queued for capture. Future features planed for the VIN driver is support for outputting frames in SEQ_TB/BT format and to do that it's important that capture starts from the first buffer slot, VnMB1. We are guaranteed that capturing always happens in sequence (VnMB1 -> VnMB2 -> VnMB3 -> VnMB1). So drop up to two frames when starting capturing so that the driver always returns buffers in the same order they are queued and prepare for SEQ_TB/BT output. Signed-off-by:
