From e68ce7c4937f4e747238d42514a78812c3f2d38a Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Tue, 21 Nov 2017 20:50:01 -0200 Subject: [PATCH] ARM: dts: imx6sx: Fix the PCI representation Currently the imx pci driver fails to probe on i.MX6SX. Fix the PCI representation so that the driver can be probed and PCI devices can be detected.
