This patch series primarily focus on improving type consistency and ensuring proper handling of timeout values. The changes aim to enhance the redability and maintainability of the serial core. Greg, sorry for the confusion. I started the patch series with 3 patches. I submitted improvised patches based on review comments for each patch in the series instead of submitting all the patches at once. This may have caused confusion, as each patch is now at a different version, with one patch at v2 (NACKED) the second one ready for v2, and the third at v4. >From now on, I will increment the version for the whole series instead of for individual patches. I have now submitted the series as v5 to avoid duplicate version numbers. In v5 it has two patches [v4 3/3] and [v2 2/3] while [v2 1/3] discarded.
