Before I start, I have a few questions regarding the process of adding the ISP driver for RK3568 and upstreaming it to the Linux Kernel. I greatly appreciate any insights you can provide on the following points: 1. Integration with existing RK3399 ISP driver: Since the ISP driver for RK3399 has already been upstreamed, I would like to understand if the ISP driver for RK3568 will be added to the existing RK3399 ISP driver or if it will be a completely new driver ? 2. Upstreaming process and staging: I would like to know if the upstreaming process for the RK3568 ISP driver will involve starting with the downstream driver and adding it to the staging area. From there, would it be merged into the media subsystem or follow a different process altogether? 3. Permission requirements from Rockchip: To ensure a smooth upstreaming process, I would like to know if I need any permissions or approvals from Rockchip, the manufacturer of the RK3568 chipset. If permissions are required, could you please guide me on how to obtain them? I would also like to mention that while this is my first time upstreaming a full driver, I do have some experience working with the media subsystem. I am willing to devote the necessary time and effort to learn and contribute effectively to the upstreaming process also I have Rock 3A development board, which will be helpful in testing the ISP driver. Thank you very much for considering my request. I eagerly await your responses and any direction you and the mailing list members can provide.
