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.

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.

The host will have atmost one KVP transaction outstanding at any + * given point in time. The host side iteration stops when the guest returns + * an error.

The + * kernel and user-level daemon communicate using a connector channel. + * + * The user mode component first registers with the + * the kernel component. Subsequently, the kernel component requests, data + * for the specified keys. In response to this message the user mode component + * fills in the value corresponding to the specified key. We overload the + * sequence field in the cn_msg header to define our KVP message types. + * + * + * The kernel component simply acts as a conduit for communication between the + * Windows host and the user-level daemon. The kernel component passes up the + * index received from the Host to the user-level daemon.
