Expand description

@brief Helper function to find the maximum possible duty resolution in bits for ledc_timer_config()

@param src_clk_freq LEDC timer source clock frequency (Hz) (See doxygen comments of ledc_clk_cfg_t or get from esp_clk_tree_src_get_freq_hz) @param timer_freq Desired LEDC timer frequency (Hz)

@return - 0 The timer frequency cannot be achieved - Others The largest duty resolution value to be set
