5- compatible : should be one of the following.
6       * zte,zx296718-tdm
7- reg : physical base address of the controller and length of memory mapped
8    region.
9- clocks : Pairs of phandle and specifier referencing the controller's clocks.
10- clock-names: "wclk" for the wclk.
11               "pclk" for the pclk.
12-#clock-cells: should be 1.
13- zte,tdm-dma-sysctrl : Reference to the sysctrl controller controlling
14    the dma. includes:
15	phandle of sysctrl.
