From 79d946837c042fba3e9ba2726f3cfa56aa408e16 Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Fri, 26 Jul 2013 10:17:47 -0300 Subject: bus: mvebu-mbus: Add new API for the PCIe memory and IO aperture We add two optional properties to the MBus DT binding, to encode the PCIe memory and IO aperture. This allows such information to be retrieved by -for instance- the pci driver to allocate the MBus decoding windows. Correspondingly, and in order to retrieve this information, we add two new APIs.
