To obtain this information, the .get_frame_desc() routine is implemented. This routine, in turn, calls .get_frame_desc() on the remote sensor connected to the CSI2 bridge.

As a result, `rzg2l_cru_format_from_pixel()` is guaranteed to return a non-NULL value, making the check redundant. Additionally, the return type of `rzg2l_cru_format_bytesperline()` is `u32`, but the code returned `-EINVAL`, a negative value. This mismatch is now resolved by removing the invalid error return path.

New helper functions, `rzg2l_cru_ip_format_to_fmt()` and `rzg2l_cru_ip_index_to_fmt()`, are added to retrieve format information based on 4CC format and index, respectively. These helpers allow the removal of the now redundant `rzg2l_cru_format_from_pixel()` function. The new helpers are used in `rzg2l_cru_format_bytesperline()`, `rzg2l_cru_format_align()`, and `rzg2l_cru_enum_fmt_vid_cap()`, streamlining the handling of supported formats and improving code maintainability.

This simplifies the code by removing an unnecessary function call and directly multiplying the image width by the `bpp` (bytes per pixel) from the format structure.

This change allows the removal of `rzg2l_cru_mc_validate_format()`. Note, the fmt.format.code and fmt.format.field checks have be dropped as the subdev .set_fmt() handler ensures that those fields always hold valid values.

linux-media@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 From: Lad Prabhakar 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.
