3Required properties:
4
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.
16 register offset in sysctrl for control dma.
17 mask of the register that be written to sysctrl.
