From 6ab11462c68499933bd9b5d52a710f4e18a9e43e Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Fri, 16 Jun 2023 17:39:13 -0300 Subject: [PATCH] ASoC: fsl-asoc-card: Allow passing the number of slots in use Currently, fsl-asoc-card supports passing the width of the TDM slot, but not the number of slots in use, as it harcodes it as two slots. Add support for passing the number of slots in use.
