This PR was entirely generated, committed, and pushed by AI.
Due to the nature of AIGC and a prompt instructing the AI to be as exhaustive as possible, some parts of the documentation may feel redundant.
If you find the generated driver documentation useful, feel free to modify and use it—just please remember to retain my SN. However, if you feel the driver is poorly written, please contact me, and I will remove your specific driver commit from this PR.
I sincerely hope this PR will reduce your workload.
Have a nice day :)
