120                mode, the driver will set the maximum clock frequency to a high

122                it was already opened by another process). The driver will set
123                the max clock frequency to a low value when there are no user
124                processes that are opened on the device's file. In "manual"
125                mode, the user sets the maximum clock frequency by writing to
