Hi Dave,

this tag contains a single patch to fix a regression introduced by the
atomic modeset conversion, with can occasionally hang the system during
crtc atomic_disable by disabling the display controller module and plane
IDMAC channels in the wrong order.

regards
Philipp

  drm/imx: disable planes before DC (2016-11-09 10:35:50 +0100)

imx-drm: fix possible hangup when disabling crtcs

- only ever disable the display controller (DC) module after all plane
  IDMAC channels are stopped. This fixes a regression introduced by the
  atomic modeset conversion.
