    1 ZTE TDM DAI driver
    2 
    3 Required 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.
   18 
   19 Example:
   20 
   21         tdm: tdm@1487000 {
   22                 compatible = "zte,zx296718-tdm";
   23                 reg = <0x01487000 0x1000>;
   24                 clocks = <&audiocrm AUDIO_TDM_WCLK>, <&audiocrm AUDIO_TDM_PCLK>;
   25                 clock-names = "wclk", "pclk";
   26                 #clock-cells = <1>;
   27                 pinctrl-names = "default";
   28                 pinctrl-0 = <&tdm_global_pin>;
   29                 zte,tdm-dma-sysctrl = <&sysctrl 0x10c 4>;
   30         };
