37 * DRC configurations are specified with a label and a set of register
38 * values to write (the enable bits will be ignored). At runtime an
39 * enumerated control will be presented for each DRC block allowing
40 * the user to choose the configration to use.
42 * Configurations may be generated by hand or by using the DRC control
43 * panel provided by the WISCE - see http://www.wolfsonmicro.com/wisce/
