From 5b40516b2f5fb9b2a7d6d3e2e924f12ec9d183a8 Mon Sep 17 00:00:00 2001 From: Mathieu Olivari <mathieu@codeaurora.org> Date: Tue, 21 Apr 2015 19:01:42 -0700 Subject: [PATCH 8/9] ARM: dts: qcom: add pcie nodes to ipq806x platforms qcom-pcie driver now supports version 0 of the controller. This change adds the corresponding entries to the IPQ806x dtsi file and corresponding platform (AP148).
