This does not fix any bug - this is just a code simplification. As np is not used after passing it to v4l2_fwnode_endpoint_parse() its refcount can be decremented immediately and at one location. Signed-off-by:

The endpoint allocated by of_graph_get_next_endpoint() needs an of_node_put() in both error and success path. As ep is not used the refcount decrement can be right after the last use of ep. Fixes: commit 37404f91 ("[media] stm32-dcmi: STM32 DCMI camera interface driver") 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).

Use the new renesas-ceu camera driver in kfr2r09 board file instead of the soc_camera based sh_mobile_ceu_camera driver.

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:

The omap media driver can be built-in while the v4l2 core is a loadable module. This is a mistake and leads to link errors: drivers/media/platform/omap/omap_vout.o: In function `omap_vout_remove': omap_vout.c:(.text+0xec): undefined reference to `v4l2_device_unregister' omap_vout.c:(.text+0x140): undefined reference to `video_device_release' omap_vout.c:(.text+0x150): undefined reference to `video_unregister_device' omap_vout.c:(.text+0x15c): undefined reference to `v4l2_ctrl_handler_free' An explicit Kconfig dependency on VIDEO_V4L2 avoids the problem.

The Renesas Fine Display Processor driver is used on Renesas R-Car SoCs only. Since commit 9b5ba0df ("ARM: shmobile: Introduce ARCH_RENESAS") is ARCH_RENESAS a more appropriate platform dependency than the legacy ARCH_SHMOBILE, hence use the former. This will allow to drop ARCH_SHMOBILE on ARM and ARM64 in the near future. Signed-off-by:
