X-BeenThere: alsa-devel@alsa-project.org X-Mailman-Version: 2.1.14 Precedence: list List-Id: "Alsa-devel mailing list for ALSA developers - http://www.alsa-project.org" List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: alsa-devel-bounces@alsa-project.org Sender: alsa-devel-bounces@alsa-project.org X-Virus-Scanned: ClamAV using ClamSMTP For most cases the rx_mask and tx_mask params have no use for snd_soc_dai_set_tdm_slot(), because they could be generated by {XXX_ .}of_xlate_tdm_slot_mask(). This patch add snd_soc_dai_set_tdm_slot_xlate() which will replace the snd_soc_dai_set_tdm_slot() in some use cases to simplify the code. And for some CODECs or CPU DAI devices there needed much more work to support the .of_xlate_tdm_slot_mask feature. This patch can be applied to most use case of the current DAI drivers.
