From 3ba5f74a541f77bfb6904e684e2cf0bfad005106 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 26 Nov 2015 19:51:30 -0700 Subject: dm: pci: Disable PCI compatibility functions by default We eventually need to drop the compatibility functions for driver model. As a first step, create a configuration option to enable them and hide them when the option is disabled.
