fimc_md_is_isp_available In fimc_md_is_isp_available(), of_get_child_by_name() is called to check if FIMC-IS is available. Current code does not decrement the refcount of the returned device node, which causes an OF node reference leak. Fix it by calling of_node_put() at the end of the variable scope.

Since commit 88785982a19d ("media: vb2: use lock if wait_prepare/finish are NULL") it is no longer needed to set the wait_prepare/finish vb2_ops callbacks as long as the lock field in vb2_queue is set. Since the vb2_ops_wait_prepare/finish callbacks already rely on that field, we can safely drop these callbacks. This simplifies the code and this is a step towards the goal of deleting these callbacks.

Add a 'yuv' flag to the `rzg2l_cru_ip_format` structure to indicate whether a given format is YUV-based and update the `rzg2l_cru_ip_formats` array with this flag appropriately. This change enables a more efficient way to check if the input and output formats use the same colorspace. With this change, we can eliminate the use of `v4l2_format_info()` in `rzg2l_cru_initialize_image_conv()` as the necessary details for the source and destination formats are already available through the `yuv` flag.

`WARN_ON(!fmt)` check in `rzg2l_cru_format_bytesperline()` is unnecessary because the `rzg2l_cru_format_align()` function ensures that a valid `pixelformat` is set before calling `rzg2l_cru_format_bytesperline()`.

Additionally, the return type of `rzg2l_cru_format_bytesperline()` is `u32`, but the code returned `-EINVAL`, a negative value.

The VIN is usually capable of converting from most media bus formats to a range of different pixel formats. However if the input media bus format is a RAW10 format this is not possible so the corresponding pixel output format is forced.

The V4M is the second Gen4 device that is enabled in the rcar-csi2 driver. There is much overlap with the already supported V4H device. The registers that where new on Gen4 and where added with the V4H prefix are retained and only new registers unique to the V4M are added with the new V4M prefix. This follows the style for when V4H was added which had an overlap with Gen3 registers. The V4M CSI-2 receiver supports D-PHY mode only, either in 1-, 2- or 4-lane configuration. The datasheets do not document lane swapping and is left out for now. While the V4M only supports D-PHY the configuration for it is added in such a way that it can be reused for V4H which supports both C-PHY and D-PHY. No known SoC exists to test the D-PHY configuration on V4H so it's not wired-up.
