     * Palmas 32KHz clocks *
     
     Palmas device has two clock output pins for 32KHz, KG and KG_AUDIO.
     
     This binding uses the common clock binding ./clock-bindings.txt.
     
     Required properties:
     - compatible :  "ti,palmas-clk32kg" for clk32kg clock
                     "ti,palmas-clk32kgaudio" for clk32kgaudio clock
    - #clock-cells : shall be set to 0.
    
    Optional property:
    - ti,external-sleep-control: The external enable input pins controlled the
            enable/disable of clocks.  The external enable input pins ENABLE1,
            ENABLE2 and NSLEEP. The valid values for the external pins are:
                    PALMAS_EXT_CONTROL_PIN_ENABLE1 for ENABLE1 pin
                    PALMAS_EXT_CONTROL_PIN_ENABLE2 for ENABLE2 pin
                    PALMAS_EXT_CONTROL_PIN_NSLEEP for NSLEEP pin
            Option 0 or missing this property means the clock is enabled/disabled
            via register access and these pins do not have any control.
            The macros of external control pins for DTS is defined at
            dt-bindings/mfd/palmas.h
    
    Example:
            #include <dt-bindings/mfd/palmas.h>
            ...
            palmas: tps65913@58 {
                    ...
                    clk32kg: palmas_clk32k@0 {
                            compatible = "ti,palmas-clk32kg";
                            #clock-cells = <0>;
                            ti,external-sleep-control = <PALMAS_EXT_CONTROL_PIN_NSLEEP>;
                    };
                    ...
            };
