From d5d89c8a55ee3a57fb30a7bca346076269266cab Mon Sep 17 00:00:00 2001 From: Lijian Zhao Date: Tue, 7 May 2019 14:05:33 -0700 Subject: soc/intel/cannonlake: Fix pcie clock number Cannonlake PCH LP have total 6 pcie clocks and Cannonlake PCH H have total 16 pcie clocks. It is different with pcie root port numbers. BUG=CID 1381814 TEST=Build and boot up fine on sarien platform.
