From cfacf22e0df2e3db3e90306f830a4f6c08829b05 Mon Sep 17 00:00:00 2001 From: Richard Zhu Date: Thu, 14 Jul 2022 15:31:01 +0800 Subject: [PATCH] PCI: imx6: Call host init function directly in resume Call imx6_pcie_host_init() instead of duplicating codes in resume. Note that this also means we do MPLL setup again during resume, which we didn't do before.
