84  * snd_soc_tdm_params_to_bclk - calculate bclk from params and tdm slot info.
86  * Calculate the bclk from the params sample rate, the tdm slot count and the
87  * tdm slot width. Optionally round-up the slot count to a given multiple.
95  * I2S mode, which has a left and right phase so the number of slots is always
102  * @tdm_width:     Width in bits of the tdm slots. Must be >= 0.
103  * @tdm_slots:     Number of tdm slots per frame. Must be >= 0.
