+ * _add_hwmod_clocks_clkdev - Add clkdev entry for hwmod optional clocks
+ * and main clock
+ * @od: struct omap_device *od
+ * @oh: struct omap_hwmod *oh
+ *
+ * For the main clock and every optional clock present per hwmod per
+ * omap_device, this function adds an entry in the clkdev table of the
+ * form <dev-id=dev_name, con-id=role> if it does not exist already.
+ *
+ * The function is called from inside omap_device_build_ss(), after
+ * omap_device_register.
+ *
+ * This allows drivers to get a pointer to its optional clocks based on its role
+ * by calling clk_get(<dev*>, <role>).
+ * In the case of the main clock, a "fck" alias is used.
+ *
+ * No return value.
