Hello,

This patch series addresses an issue in the Xilixn ZynqMP DPDMA driver
that causes a display freeze after 65536 frames. The first three patches
include a small compilation breakage issue (1/4) and enhancements to the
messages logged by the driver (2/4 and 3/4). The last patch fixes the
freeze bug. Please see individual patches for details.

Laurent Pinchart (4):
  dmaengine: xilinx: dpdma: Add missing dependencies to Kconfig
  dmaengine: xilinx: dpdma: Print channel number in kernel log messages
  dmaengine: xilinx: dpdma: Print debug message when losing vsync race
  dmaengine: xilinx: dpdma: Limit descriptor IDs to 16 bits
