From 1bdf09d91aebbd4aca80fe9ee2a75368662f3dc6 Mon Sep 17 00:00:00 2001 From: David Wu Date: Mon, 25 Oct 2021 11:54:41 +0800 Subject: mb/google/brya/var/kano: Disable unused PCIE root port in devicetree The baseboard enables PCIe RPs 6, 8 and 9, but kano doesn't use these. Having them enabled will occasionally cause suspend attempts to fail, therefore disable them in the overridetree. BUG=b:203389490 b:192370253 TEST=FW_NAME=kano emerge-brya coreboot and verify it builds without error.
