commit 2cce0bf617358deb2450fee87ab01a8cef7274ea
Author: Jim Paris <[email protected]>

    Support referencing a specific ADC input in DT properties
    
    This lets us do e.g.:
    
       foo {
          compatible = "bar";
          input-adcs = <&adc 4>;
       };
    
    and get DT properties like:
    
      DT_BAR_FOO_INPUT_ADCS_CONTROLLER="ADC_0"
      DT_BAR_FOO_INPUT_ADCS_INPUT=4
    
    similar to existing -gpios and -pwms support.
