[PATCH 5/6] modetest: add atomic modeset support
Hyungwon Hwang

Tue Aug 18 17:58:43 PDT 2015
This patch adds support for atomic modeset. Using -a option, user can
make modeset to use DRM_IOCTL_MODE_ATOMIC instead of legacy IOCTLs.
Also, by using -W option, user can set the value of each object's property.
