/*
 * We need a clock management system that works across unrelated SoCs and
 * devices.  For now, to keep imx development moving, define some barebones
 * functionality that can be shared within the imx family by having each SoC
 * implement functions with a common name.
 *
 * The usb enable functions are best-effort.  They turn on the usb otg, host,
 * and phy clocks in a SoC-specific manner, but it may take a lot more than that
 * to make usb work on a given board.  In particular, it can require specific
 * pinmux setup of gpio pins connected to external phy parts, voltage regulators
 * and overcurrent detectors, and so on.  On such boards, u-boot or other early
 * board setup code has to handle those things.
