From d23f3839fe97d8dce03dfc8b5640883ea06050e9 Mon Sep 17 00:00:00 2001 From: Kishon Vijay Abraham I Date: Tue, 8 Aug 2017 11:10:24 +0530 Subject: [PATCH] ARM: dts: DRA7: Add pcie1 dt node for EP mode Add pcie1 dt node in order for the controller to operate in endpoint mode. However since none of the dra7 based boards have slots configured to operate in endpoint mode, keep EP mode disabled.
