From 5b302b2ed213b8cfbeb901aaed650bf73c3742fc Mon Sep 17 00:00:00 2001 From: Eric Lai Date: Sat, 5 Dec 2020 16:49:43 +0800 Subject: soc/intel/alderlake: Refactor PCIE port config Refactor PCIE port config structure. Make it easier to map from schematic. We don't have to convert the PCIE ports RP number and CLK source in devicetree. All the convert will be done by SoC level.
