clk: add function documentation for clk_hw_round_rate()

}

EXPORT_SYMBOL_GPL(__clk_determine_rate);

/**

 * clk_hw_round_rate() - round the given rate for a hw clk

 * @hw: the hw clk for which we are rounding a rate

 * @rate: the rate which is to be rounded

 *

 * Takes in a rate as input and rounds it to a rate that the clk can actually

 * use.

 *

 * Context: prepare_lock must be held.

 *          For clk providers to call from within clk_ops such as .round_rate,

 *          .determine_rate.

 *

 * Return: returns rounded rate of hw clk if clk supports round_rate operation

 *         else returns the parent rate.
