From 7d6ec0ce7a11ff7ce25d4e1a8b23903f92489fde Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Wed, 25 Mar 2020 16:29:05 -0500 Subject: [PATCH] ASoC: rt1308-sdw: use slot and rx_mask to configure stream If the DAI was configured with a set_tdm_slots() call, use the information. A platform or machine driver may configure each amplifier to extract different bitSlots from the frame, or extract the same data and use processing to generate the relevant output. The latter case is easier to handle in case of orientation changes.
