ZTE TDM DAI driver
Required properties:
- compatible : should be one of the following.
* zte,zx296718-tdm
- reg : physical base address of the controller and length of memory mapped
region.
- clocks : Pairs of phandle and specifier referencing the controller's clocks.
- clock-names: "wclk" for the wclk.
"pclk" for the pclk.
-#clock-cells: should be 1.
- zte,tdm-dma-sysctrl : Reference to the sysctrl controller controlling
the dma. includes:
phandle of sysctrl.
register offset in sysctrl for control dma.
