This PR appears to be missing crucial information to meet the NuttX requirements. While it lists the files changed, it lacks important details.

Here's a breakdown of what's missing and how to improve it:

Summary:

• Missing "Why": The PR states what was changed (using a small lock), but not why. Is this for performance improvement? Deadlock avoidance? Explain the motivation for the change.
• Missing "How": It's unclear what "small lock" means. What locking mechanism is being used? How does it differ from the previous locking? Provide more technical details.
• Missing Issue References: Are there related NuttX issues this PR addresses? If so, link them.

Impact:

The current impact section simply repeats the list of files. This is insufficient. Address each impact point specifically:

• New Feature/Changed Feature: Clarify if a new feature is introduced or if existing functionality is modified.
• Impact on User: Will the user experience any changes? Likely no, but explicitly state that.
• Impact on Build: Will the build process be affected? Likely no, but explicitly state that.
• Impact on Hardware: This is relevant as it affects specific architecture and boards. Briefly explain why these changes are needed for the imx9.
• Impact on Documentation: Does this change require documentation updates? If not, explicitly state "NO".
• Impact on Security: Does using a smaller lock have security implications? If not, explicitly state "NO".
• Impact on Compatibility: Are there backward compatibility concerns? If not, explicitly state "NO".

Testing:

Simply stating "CI" is not enough.

• Build Host(s): Specify the environment used for testing (OS, CPU, Compiler).
• Target(s): Be specific about the target architecture, board, and configuration used for testing.
• Testing Logs: Provide actual logs demonstrating the behavior before and after the change. Show how the change addresses the original issue or improves performance. If logs are too extensive, provide a summary and link to a separate file or CI run.

Example of an Improved Summary:

This change replaces the existing mutex locks in the specified drivers with smaller, more efficient spinlocks. This is done to improve performance in interrupt context, where the previous mutex implementation could lead to unnecessary context switches. This addresses the performance regression observed in NuttX Issue #XXXX.

By providing these missing details, the PR will be much clearer, easier to review, and more likely to be accepted.
