MLK-15925-3 drm/imx: dpu: kms: Avoid plane src hot migration between 2 disps The DPU fetch units(backing DRM planes) are shared by two displays(a.k.a, CRTCs). Since the shadow trigger/load mechanism of each display(CRTC) is independent from each other, on-the-fly/hot migration of plane source is likely to cause resouce conflict issue when the shadow registers are loaded. This patch changes the way we assign fetch units for each DRM planes so that we may avoid the migrations from happening. Thanks to the DRM atomic check nature, cold migrations still can be supported.
