From ee73b781c1e13daee67e149f1828d7166e5ea627 Mon Sep 17 00:00:00 2001 From: Dimitri Staessens Date: Mon, 1 Oct 2018 17:35:31 +0200 Subject: ipcpd: Merge dt_pci into dt source This merges the dt_pci code into the dt source. It simplifies the code base, and allows inline compilation. Removes unnecessary includes.
