From: Kedareswara rao Appana appana.durga.rao@xilinx.com
Zynqmp DMA driver expects two clocks (main clock and apb clock) For LPDDMA channels the two clocks are missing in the Dma node resulting probe failure.
xilinx-zynqmp-dma ffa80000.dma: main clock not found. xilinx-zynqmp-dma ffa80000.dma: Probing channel failed xilinx-zynqmp-dma: probe of ffa80000.dma failed with error -2
This patch fixes this issue.

Am I missing something? Adding 'clock-names' without 'clocks' doesn't seem right.
