The dpsub driver uses the DMA engine API, and thus selects DMA_ENGINE to provide that API. DMA_ENGINE depends on DMADEVICES, which can be deselected by the user, creating a possibly unmet indirect dependency:
WARNING: unmet direct dependencies detected for DMA_ENGINE Depends on [n]: DMADEVICES [=n] Selected by [m]: - DRM_ZYNQMP_DPSUB [=m] && HAS_IOMEM [=y] && (ARCH_ZYNQMP || COMPILE_TEST [=y]) && COMMON_CLK [=y] && DRM [=m] && OF [=y]
Add a dependency on DMADEVICES to fix this.
