From e921911f1008169d236c4d2bd3e169a176cdf45c Mon Sep 17 00:00:00 2001 From: Usha P Date: Mon, 3 Feb 2020 18:54:19 +0530 Subject: mb/intel/jasperlake_rvp: Enable only required PCIE root ports Jasper Lake SOC has 8 PCIe root ports. Cleaning up the root ports as per Jasper Lake. This patch updates the devicetree to enable WLAN and NVME for jasperlake_rvp and removes the other root port configurations which are not required.
