     33 * struct omap_opp_def - OMAP OPP Definition
     34 * @hwmod_name:	Name of the hwmod for this domain
     35 * @freq:	Frequency in hertz corresponding to this OPP
     36 * @u_volt:	Nominal voltage in microvolts corresponding to this OPP
     37 * @default_available:	True/false - is this OPP available by default
     38 *
     39 * OMAP SOCs have a standard set of tuples consisting of frequency and voltage
     40 * pairs that the device will support per voltage domain. This is called
     41 * Operating Points or OPP. The actual definitions of OMAP Operating Points
     42 * varies over silicon within the same family of devices. For a specific
     43 * domain, you can have a set of {frequency, voltage} pairs and this is denoted
     44 * by an array of omap_opp_def. As the kernel boots and more information is
     45 * available, a set of these are activated based on the precise nature of
     46 * device the kernel boots up on. It is interesting to remember that each IP
     47 * which belongs to a voltage domain may define their own set of OPPs on top
     48 * of this - but this is handled by the appropriate driver.
