[PATCH v2 0/3] PCIe: Refactor link speed configuration with unified macro
From: Hans Zhang
Date: Sat Jun 07 2025 - 11:56:54 EST
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 v2:
- s/PCIE_SPEED2LNKCTL2_TLS_ENC/PCIE_SPEED2LNKCTL2_TLS
- The patch commit message were modified.
