The changes include restructuring the DPF configuration handling, improving readability, and adding support for sensor-specific DPF parameters. Support mode selection base on tuning parameters Key changes: - Inlined parseModes into parseConfig for cleaner initialization. - Refactored mode lookup to use a dictionary, facilitating name-based lookup in tuning files. - Introduced ActiveMode as an optional tuning parameter to set the default DPF state. - Improved code structure in prepare() by using helper functions for enabled and disabled states. - Enhanced debug logging for ISP parameter verification. - Provided initial tuning data for IMX219, OV5640. changes since v12: - patch 3: Code format and style improvements: Remove curly braces for single-line if statements. - patch 7: Delete ov5647 tuning file from this series.
