Changes in V8:
1. Rebased on tag next-20241220.
2. Use raw_spinlock_t instead of spinlock_t.
3. Remove redundant codes in CTCU driver:
- Eliminate unnecessary parameter validations.
- Correct log level when an error occurs.
- Optimize codes.
4. Correct the subject prefix for DT patch.
5. Collected reviewed-by tag from Konrad Dybcib for DT patch.
