    3 Binding for keystone PLLs. The main PLL IP typically has a multiplier,
    4 a divider and a post divider. The additional PLL IPs like ARMPLL, DDRPLL
    5 and PAPLL are controlled by the memory mapped register where as the Main
    6 PLL is controlled by a PLL controller registers along with memory mapped
    7 registers.
    8 
    9 This binding uses the common clock binding[1].

   12 
   13 Required properties:
   14 - #clock-cells : from common clock binding; shall be set to 0.
   15 - compatible : shall be "ti,keystone,main-pll-clock" or "ti,keystone,pll-clock"
   16 - clocks : parent clock phandle
   17 - reg - pll control0 and pll multipler registers
   18 - reg-names : control, multiplier and post-divider. The multiplier and
   19                 post-divider registers are applicable only for main pll clock
   20 - fixed-postdiv : fixed post divider value. If absent, use clkod register bits
   21                 for postdiv
   22 
   23 Example:
   24         mainpllclk: mainpllclk@2310110 {
   25                 #clock-cells = <0>;
   26                 compatible = "ti,keystone,main-pll-clock";
   27                 clocks = <&refclksys>;
   28                 reg = <0x02620350 4>, <0x02310110 4>, <0x02310108 4>;
   29                 reg-names = "control", "multiplier", "post-divider";
   30                 fixed-postdiv = <2>;
   31         };
   32 
   33         papllclk: papllclk@2620358 {

   39                 reg-names = "control";
   40         };
   41 
   42 Required properties:
   43 - #clock-cells : from common clock binding; shall be set to 0.
   44 - compatible : shall be "ti,keystone,pll-mux-clock"
   45 - clocks : link phandles of parent clocks
   46 - reg - pll mux register
   47 - bit-shift : number of bits to shift the bit-mask
   48 - bit-mask : arbitrary bitmask for programming the mux
   49 
   50 Optional properties:
   51 - clock-output-names : From common clock binding.

   53 Example:
   54         mainmuxclk: mainmuxclk@2310108 {
   55                 #clock-cells = <0>;
   56                 compatible = "ti,keystone,pll-mux-clock";
   57                 clocks = <&mainpllclk>, <&refclkmain>;
   58                 reg = <0x02310108 4>;
   59                 bit-shift = <23>;
   60                 bit-mask = <1>;
   61                 clock-output-names = "mainmuxclk";
   62         };
   63 
   64 Required properties:
   65 - #clock-cells : from common clock binding; shall be set to 0.
   66 - compatible : shall be "ti,keystone,pll-divider-clock"
   67 - clocks : parent clock phandle
   68 - reg - pll mux register
   69 - bit-shift : number of bits to shift the bit-mask
   70 - bit-mask : arbitrary bitmask for programming the divider
   71 
   72 Optional properties:
   73 - clock-output-names : From common clock binding.
   74 
   75 Example:
   76         gemtraceclk: gemtraceclk@2310120 {
