charset="utf-8" From: Lad Prabhakar Refactor the handling of supported formats in the RZ/G2L CRU driver by moving the `rzg2l_cru_ip_format` struct to the common header to allow reuse across multiple files and adding pixelformat and bpp members to it. This change centralizes format handling, making it easier to manage and extend. - Moved the `rzg2l_cru_ip_format` struct to `rzg2l-cru.h` for better accessibility. - Added format, datatype and bpp members to `rzg2l_cru_ip_format` struct - Dropped rzg2l_cru_formats - Introduced helper functions `rzg2l_cru_ip_code_to_fmt()`, `rzg2l_cru_ip_pix_fmt_to_bpp()`, and `rzg2l_cru_ip_index_to_pix_fmt()` to streamline format lookups. - Refactored the `rzg2l_cru_csi2_setup` and format alignment functions to utilize the new helpers.
