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

Posted by Hans Zhang 7 months ago

This series standardizes PCIe link speed handling across multiple drivers
by introducing a common conversion macro PCIE_SPEED2LNKCTL2_TLS_ENC. 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.
