[PATCH 1/3] PCI: dw-rockchip: Remove unused PCIE_CLIENT_GENERAL_DEBUG
Posted by Hans Zhang 9 months, 3 weeks ago
The PCIE_CLIENT_GENERAL_DEBUG register offset is defined but never
used in the driver. Its presence adds noise to the register map and
may mislead future developers.

Remove this redundant definition to keep the register list minimal
and aligned with actual hardware usage.
