From 27a18e9e673f03b48a881e133a532c1619b711c7 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.
