[PATCH v3 0/3] PCIe: Refactor link speed configuration with unified macro

Posted by Hans Zhang 1 month, 2 weeks ago

This series standardizes PCIe link speed handling across multiple drivers
by introducing a common conversion macro PCIE_SPEED2LNKCTL2_TLS(). The
changes eliminate redundant speed-to-register mappings and simplify code
maintenance:

The refactoring improves code consistency and reduces conditional
branching, while maintaining full backward compatibility with existing
speed settings.

Changes for v3:
- Rebase to v6.17-rc1.
- Gentle ping.

Changes for v2:
- s/PCIE_SPEED2LNKCTL2_TLS_ENC/PCIE_SPEED2LNKCTL2_TLS
- The patch commit message were modified.
