+ * struct clk_ops - Callback operations for hardware clocks; these are to
+ * be provided by the clock implementation, and will be called by drivers
+ * through the clk_* api.
+ *
+ * @prepare: Prepare the clock for enabling. This must not return until
+ * the clock is fully prepared, and it's safe to call clk_enable.
+ * This callback is intended to allow clock implementations to
+ * do any initialisation that may sleep. Called with
+ * prepare_lock held.
+ *
+ * @unprepare: Release the clock from its prepared state. This will typically
+ * undo any work done in the @prepare callback. Called with
+ * prepare_lock held.
+ *
+ * @enable: Enable the clock atomically. This must not return until the
+ * clock is generating a valid clock signal, usable by consumer
+ * devices. Called with enable_lock held. This function must not
+ * sleep.
+ *
+ * @disable: Disable the clock atomically. Called with enable_lock held.
+ * This function must not sleep.
+ *
+ * @recalc_rate Recalculate the rate of this clock, by quering hardware. The
+ * parent rate is an input parameter. It is up to the caller to
+ * insure that the prepare_mutex is held across this call.
+ * Returns the calculated rate. Optional, but recommended - if
+ * this op is not set then clock rate will be initialized to 0.
+ *
+ * @round_rate: Given a target rate as input, returns the closest rate actually
+ * supported by the clock.
+ *
+ * @get_parent: Queries the hardware to determine the parent of a clock. The
+ * return value is a u8 which specifies the index corresponding to
+ * the parent clock. This index can be applied to either the
+ * .parent_names or .parents arrays. In short, this function
+ * translates the parent value read from hardware into an array
+ * index. Currently only called when the clock is initialized by
+ * __clk_init. This callback is mandatory for clocks with
+ * multiple parents. It is optional (and unnecessary) for clocks
+ * with 0 or 1 parents.
+ *
+ * @set_parent: Change the input source of this clock; for clocks with multiple
+ * possible parents specify a new parent by passing in the index
+ * as a u8 corresponding to the parent in either the .parent_names
+ * or .parents arrays. This function in affect translates an
+ * array index into the value programmed into the hardware.
+ * Returns 0 on success, -EERROR otherwise.
+ *
+ * @set_rate: Change the rate of this clock. If this callback returns
+ * CLK_SET_RATE_PARENT, the rate change will be propagated to the
+ * parent clock (which may propagate again if the parent clock
+ * also sets this flag). The requested rate of the parent is
+ * passed back from the callback in the second 'unsigned long *'
+ * argument. Note that it is up to the hardware clock's set_rate
+ * implementation to insure that clocks do not run out of spec
+ * when propgating the call to set_rate up to the parent. One way
+ * to do this is to gate the clock (via clk_disable and/or
+ * clk_unprepare) before calling clk_set_rate, then ungating it
+ * afterward. If your clock also has the CLK_GATE_SET_RATE flag
+ * set then this will insure safety. Returns 0 on success,
+ * -EERROR otherwise.
+ *
+ * The clk_enable/clk_disable and clk_prepare/clk_unprepare pairs allow
+ * implementations to split any work between atomic (enable) and sleepable
+ * (prepare) contexts. If enabling a clock requires code that might sleep,
+ * this must be done in clk_prepare. Clock enable code that will never be
+ * called in a sleepable context may be implement in clk_enable.
+ *
+ * Typically, drivers will call clk_prepare when a clock may be needed later
+ * (eg. when a device is opened), and clk_enable when the clock is actually
+ * required (eg. from an interrupt). Note that clk_prepare MUST have been
+ * called before clk_enable.
