Merge arlied/drm-next into drm-misc-next
We need to pull 66660d4cf21b (drm: add connector info/property for non-desktop displays [v2]) into drm-misc-next to continue the development of the display rotation series. Effectively this also pulls 4.15-r2 into drm-misc-next. Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.com>

+Non-Transparent Bridge (NTB) Driver
+===================================

+An NTB driver is provided for the switchtec hardware in switchtec_ntb.
+Currently, it only supports switches configured with exactly 2
+partitions. It also requires the following configuration settings:

+* Both partitions must be able to access each other's GAS spaces.
+ Thus, the bits in the GAS Access Vector under Management Settings
+ must be set to support this.
