From a71cd51e2aae333dde272ff83661f9ef0fe62a30 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?C=C3=A9dric=20Le=20Goater?= Date: Wed, 12 Jan 2022 11:28:27 +0100 Subject: [PATCH] ppc/pnv: Attach PHB3 root port device when defaults are enabled MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This cleanups the PHB3 model a bit more since the root port is an independent device and it will ease our task when adding user created PHB3s. pnv_phb_attach_root_port() is made public in pnv.c so it can be reused with the pnv_phb4 root port later.
